It sounds like you're trying to wire up a dryer or an oven. Your old appliance has an old 3 wire cord and your home has a 4 wire plug. If you downgrade that plug your home no longer meets code. Put the new outlet back and install a modern cord on the appliance. New 4 prong plugs are required for new work. What you're suggesting is dangerous and violates the National Electrical Code and can cause you some serious problems with the insurance company, building department and fire department if the house catches fire and you're caught. Use the proper wire, breakers, plugs and outlets for the application. It's not that much more expensive and everything will work properly when you're done.

How do you wire up 2 120V strands into a 240V if the 3 prong receptacle has 2 hots and a neutral but no place for the grounds and should you just wirenut the grounds and tuck them in the box?

On the three prong 240 v receptacle there shouldn't be a neutral because it's not needed. Should be two hots and the ground and tuck neutrals in box.


How do you wire a ceiling light fixture to a receptacle that has two black wires and two white wires?

Black is Hot and White is Neutral and there should also be a bare ground wire. One black/white/bare cable is supply for receptacle and the other is connected in parallel and goes to another outlet. You need your ceiling fixture connected to one of the wires coming into the receptacle box, Black to Black, White to White and Bare to Bare. However, assume you want to be able to switch the ceiling light with a wall switch unless there is to be a pull chain on ceiling light. To connect switch run a new wired from the receptacle to a switch and run a wire from switch to ceiling fixture. At original outlet connect as described above. At switch connect White wires together with a wirenut, then do the same for the bare wires. Connect Black wire going to ceiling to one side or switch and Black wire coming from original receptacle to other side of switch.


Is there a wiring diagram for a light switch pdf?

A light switch wiring is simple. You just need to contend with three wires. For typical home wiring you would have a hot wire (black), a neutral wire (white) and a ground wire (bare or green). You switch only the hot wire. The hot wire from the supply side is connected to one terminal of the switch. Connect the hot wire for the load to the other side of the switch. Connect the white wires together with a wirenut. The ground wire is connected to the ground terminal of the switch. This is often connected to the supply and load grounds via a pigtail wire and a wirenut connecting three wires together.


How do you wire an outdoor light to a light switch?

All a switch does is separate the hot side of a voltage source from the light. This means you put the switch "in series" with the black wire going to the light fixture. The black wire from supply goes into one terminal of the switch and the black wire going to the light goes on the other terminal. The switch is grounded with the bare wire from supply and the white wires coming from supply and going to light are connected with a wirenut. The bare wire grounds are also connected with a wirenut.


Can you run 3 pigtails off of 1 hot feed?

Yes. Make sure you have a good twist on wires with pliers before the wirenut. Make sure wirenut is sized for 4 wires of the proper size. All pigtails should be same gauge as hot.


What is the most widely used splice or joint in interior wiring installation to extend the length of wire from one point to another?

Most modern electricians simply use a wirenut to join two wires. If a wirenut is impractical a "lineman's splice" is probably the next most common as it has minimum diameter and very high strength.


How do you wire a new light with an on-off switch using wires coming from another light?

If you have unswitched supply from a light you need to route the supply through the new switch to the new light. You want to switch the black wire and just connect the white wires together with a wirenut and connect the bare ground wires together by a separate wirenut.


How do you wire a new light with an on off switch using wires coming from an outlet?

Continue black, white and bare wires from outlet to switch box. Run light black, white and bare wires from light to switch box. Connect wire from light to one attachment on switch and black from outlet onto other switch attachment. Connect white wires together with a wirenut. Connect bare wires together with a wirenut and include a third piece of bare wire to this same wirenut. Connect the other end of this third bare wire to green screw on switch. Make sure all wires are 14 AWG if you have a 15A circuit and 12 AWG if a 20A circuit.


How do you use wire nuts?

First twist together the wires to be joined. For larger wire use lineman's pliers to apply twist. Make the twist clockwise. Then twist on the wirenut clockwise on the wires. Wirenuts are rated as to how many wires of a certain size they can hold but in general twist by hand until you can twist no more and then about 1/2 twist with pliers. If the wirenut does not get tight it is too big or internal metal portion could be clogged in some way.


How do you disconnect electrical outlet from the light switch?

If the switch just controls the outlet you would remove the switch and just wirenut the wires that went to each side of the switch together. Put a blank switch plate to cover the box. If the switch controls outlet and something else you need to determine if there is a seperate direct connection to each and then remove the outlet connection and wirenut the black lead to the outlet directly to the black lead on the supply side of the switch.


What are the splices of electrical wiring?

Always splice electric wiring in an approved junction box. Typically use a wirenut of the correct size. Specialized connectors are also available where you push the wires into a slicing device.


How do you wire a light switch to the light then an outlet?

Assuming that you want the light switched and the outlet unswitched and the supply voltage is in the switch box you do the following. Run the supply directly from the input of the switch to the outlet. Black goes to the copper colored terminal on outlet, white to silver colored terminal and ground to green screw. The white wires for outlet and light can all be wired together using a wirenut. Do the same for the grounds. Then one side of the switch is connected to the black supply and the other side of the switch to the black wire on the light.


How do you connect a switch where the power is at the light?

Run a wire from the light to the switch. At the light connect the black power wire to the black wire to the switch. Not wrap some black electric tape at each end of the white wire going to the switch (This indicates that the wire is potentially hot and not a common wire). At the switch connect the black wire to one side of the switch and the taped wire to the other side of the switch. Connect the ground (bare) wire to the green screw on the switch. Now at the light connect the taped white wire to the black wire feeding the light and connect all grounds together with a wirenut.


What might cause outlet problems without a gfci?

You need to describe the problem you are having with outlet. Most common problems are loose wires at a screw or push type connector, a wirenut coming loose, screws on side touching metal or nicks in wires causing shorts. Occasionally the outlet itself is bad internally. I have seen this after lightning strikes.


How do you find a wiring diagram of wiring a light with an on-off switch using wires coming from an outlet?

First you need to make sure that you are not overloading the existing circuit. Typically lights and outlets are on separate circuits. Check local electric codes. Basically you have three wires in outlet (black = hot, White = neutral and bare wire is ground). The wire must be rated for the protecting breaker. AWG 14 for 15 A breaker and AWG 12 for 20 A breaker. Extend all three wires to a switch box by using wirenut splices or by extending using the extra screws on outlet if there are any. At the switch box run another wire to light. (Black, White and Bare). Now at the switch connect black wire from light to one side of switch and black wire from outlet to the other side of switch. Connect two white wires together using a wirenut. Connect the bare wire to ground lug on switch and create a pigtail to connect the light bare wire to pigtail. Now connect the light. Black to Black, White to white and bare to bare wires. If light has two black wires and no white, connect one of the black light wires to white wire from switch.


How to connect electricity wire to three wired out ceiling fan?

Some ceiling fans have a black, white and sometimes blue wire. The blue wire in this case is so you can switch a light separate from fan. If your fan doesn't have a light just put a wirenut on extra wire and ignore it. If you do have a light and want it switched you'll need an extra wire run to fan, and switch that wire for light.


Can your bathroom light switch be modified so that it does not need to be on in order for the GFI outlet on the opposing wall to work?

(LIFE SAFETY WARNING! [Disclaimer]Electricity is dangerous!You can be injured or killed!Improper installations can cause fire, injury and death!Should you be doing this yourself?)GFI receptacles are now installed on what is known as a small appliance branch circuitYours is old or an add-on.If the power for the receptacle comes from the switch box directly then you can make it work all the time by moving the hot wire feeding the GFI from the 'load' side of the switch to the 'hot' - permanently live - side of the switch.Remember that you only put one wire under a screw, so you will have to make up or change splices. [wirenut connections]If you aren't up to this, get an electrician. Actually, the most likely situation is that you have a receptacle under a light over the sink at the other side of the room from the switch.They did this to get a receptacle without doing the hard job.If that is the case, you are stuck unless you want to rewire the outlet from another source: a new 20 amp circuit like it SHOULD be - tear up your bathroom and run it to the switch like the people who put it in didn't want to! Or tear up something else and get power from somewhere else that is hot all the time. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work ANDalways use an electrician's test meter having metal-tipped probes(not a simple proximity voltage indicator)to insure the circuit is, in fact, de-energized.


How do you install a pull chain switch in a fluorescent light fixture?

You have both a mechanical and electrical issue. From a mechanical standpoint you need the switch mounted securely in the fixture. The switch will have two black wires or two terminals. You need to insert the switch in series with the black wire going to the fixture. Let's say that the black wire from a supply is connected to the black wire in the fixture with a wirenut. Undo the two wires and connect each wire to a wire on the switch.


How do you hook up a live wire into two switches?

First turn off the power. You can do it a couple of ways. Take your black hot wire and connect two black pigtail wires of the correct gauge to the wire via a wirenut. Then connect each of the two pigtails to each switch. Another way if the supply wire is long enough you can strip about 1/2 inch off about 4 inches from the end. Make a "U-shaped" bend in the stripped area and put that around one switch and strip the end and connect to the other switch.


How do you disconnect an electrical outlet from a light switch?

Basically you need to connect the black supply wire directly to the outlet rather than have it go through switch. You can have two possible conditions. The first condition is that the supply comes to the switch box and connects to one side of the switch. The other side of the switch goes to the outlet. In this case just remove each black wire from the switch and connect them together with a wirenut. If the black supply wire goes to the outlet and there is another black wire going to the switch then there will also be a wire coming back from the switch. Just disconnect the wire coming from the switch to the outlet and connect the black supply wire directly to the outlet.


Is there a diagram of wiring two lights to one switch with the power at the light?

At the lights there is a black, white and bare wire from the supply. With power off you would break the black (Hot) connection at wirenut. Then you just need to run a wire to and from the switch. Assume you use standard Romex with black, white and bare wires. Connect the black wire to the black wire from supply. Connect the white wire going to the switch to the black wire going to lights. Wrap black electric tape around each end of white wire to show it is HOT. At the switch end connect the white wire to one lug on switch and black to the other. Connect the bare wire to ground on switch and at light to other bare wires.


How do you add a separate fixture along with a separate switch from an existing switch which has only 2 hot wires coming from the wall that are attached to the 1st switch?

Answer for USA, Canada and countries running a 60 Hz supply service.Most times you can't feed your load only from the switch because it doesn't have a neutral. If there are no existing power outlet branch circuits nearby you'd have to consider connecting into the existing light fixture, which is where the hot feed and neutral wires should be.If you are lucky - and by lucky I mean the cable to the switch isn't stapled in the wall (which is very unlikely) - you can use the old cable to pull through a new piece of 14-3 cable to get the neutral in the box that you will need to be able to power a new switched outlet.A new cable is needed because, as well as the "unswitched hot" and the "switched-hot return" to the light fixture, the box must have a full power service including Hot (Black), Neutral (White) and Ground (Bare Wire).However, to do this job safely, there are several things you must first check:Do your local wiring codes allow you to fit a new socket outlet in the intended place?Is the breaker protecting the lighting circuit not already overloaded by its existing lights and any extra outlets that are already in place?Will the load to be applied to the new outlet be no more than 5 amps?Even if the new outlet is to be the normal 15 amp size, a higher load current (amperage) than 5 amps could dangerously overload the existing wire size of the lighting circuit.Such overloading is a common cause of house fires!Do the following:1. Turn off the breaker controlling the switch.2. Remove the switch from the box.3. Identify the supply Hot Black Wire (Call it B1)4. Remove B1 from switch and label in some way so you'll remember what it is.5. Undo the wirenut in the box which will typically have two white wires unless the box is also being used as a junction box and there may be more than 2 white wires.6. Get a piece of the same gauge white wire long enough to reach the new outlet to make a new pigtail - strip about 3/4 in from each end - and add it to the bundle of white wires connected together. (You may need a bigger wire nut.) Make sure that all wires are solidly connected.7. Make two black wire pigtails long enough to reach the new switch and outlet and connect one end of one of them to wire B1 using a wirenut.8. Connect that black wire pigtail to one terminal of the new switch and the other black wire pigtail to the terminal on the outlet that has a brass-colored screw.9. Connect the new white wire pigtail to the terminal with the silver-colored screw on the outlet.10. Connect the black wire from the new outlet to the terminal on the other side of the new switch.11. Make a new ground pigtail and connect it from the bare wire in the box to the green screw on the new outlet.WarningsMake sure all connections are tight and no bare wires are exposed.Make sure you have identified the supply B1 wire correctly. If not you will create a switched outlet as well as whatever you were switching before.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.


How do I wire a home switch with the power running through and a leg for a light?

This is quite simple, and there is probably a diagram with the switch. Turn off the power at the main breaker panel. There is a cable with black (H=Hot, white (N=Neutral) and green (G=Ground) wires coming into the box to supply the power, and a similar cable going to the light. Connect the two G wires together and connect them also to the G (green) terminal on the switch (if it has one, it may not) and to the ground terminal on the box (if it has one, it may not). Use a wire nut to tie all the green wires together. Connect the two N wires with a wirenut. The switch has two terminals. Connect one of the hot wires to each. Asking this type of question usually means you aren't ready to do this yourself.If you get any detailed "how to do it" answer here, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or their life.

How do you convert a wall switch into an outlet with a wall switch?

Answer for USA, Canada and countries running a 60 Hz supply service.If the box containing the switch already has a full powerservices including, Hot (Black), Neutral (White) and Ground (Bare Wire) it may be possible for you to do this conversion. See below for more information on what you must check before you do it. If there are only two wires in the box - a hot unswitched "feed" wire and a "switched hot return" wire and if you are lucky - by lucky I mean the cable with the wires to the switch isn't stapled in the wall (which is very unlikely) - you may be able to use the old switch cable to pull through a new piece of 14-3 cable to get the neutral you need to power your new load in the box containing the switch. This is needed because, as well as the switched-hot return to the light fixture, the box must have a full powerservice including Hot ( Black), Neutral (White) and Ground (Bare Wire).However, to do this job safely, there are several things you must first check:Do your local wiring codes allow you to fit a new socket outlet in the intended place?Is the breaker protecting the lighting circuit not already overloaded by its existing lights and any extra outlets that are already in place?Will the load to be applied to the new outlet be no more than 5 amps?Even if the new outlet is to be the normal 15 amp size, a higher load current (amperage) than 5 amps could dangerously overload the existing wire size of the lighting circuit.Such overloading is a common cause of house fires!Do the following:1.

How do you change a 240V dedicated circuit for an electric stove to a 120V dedicated circuit for a gas stove?

For USA, Canada and countries running a 60 Hz supply service.It is best to install a new 120 volt branch circuit for the gas stove using properly sized cable and breaker and the correct type of GFCI-protected 120 volt socket outlet for use in a kitchen area. As the existing wire size is sufficient to handle 220 volts you can use it to carry 110 volts. You will need to change the receptacle and also change from a double pole breaker to a single pole breaker at the fuse panel. Unless you know what you are doing, I would suggest you hire an electrician. A very simple job that should not be too expensive.I would do nothing more than trip the breaker at the fuse panel. Out of sight out of mind.[That is not good practice! Why not provide a properly connected and protected 120 volt socket outlet near to the gas stove?]You'll want to perform what is known as a "burial".Carefully remove the wires from the main service panel and tuck them away OUTSIDE the panel. Before tucking them away snip off the bare ends, put on a wire-nut, and wrap it with electrical tape. At the kitchen outlet, snip off the bare ends and put wirenut on and tape. But leave everything INSIDE the junction box.This method allows for the unit to be hooked back up if need be.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
