Can you install two 220v receptacles for a welder in two different areas of your shop on the same circuit?
Technically no. In the USA the NFPA electrical code requires a separate circuit for each large appliance receptacle- there are a few exceptions (such as a heater and AC on same circuit) - I don't think the welder is one of the exceptions. In practice, as long as only one receptacle is used at a time, it will work fine Make sure that the wire size is correct for the current (amp) draw. This is taken off of the welder nameplate. Size the breaker to protect the wire size. If more that one welder gets plugged in the breaker will trip.
How will an electrical circuit behave if there is an open circuit?
The circuit is incomplete, you will have no continuity, no flow of current to the load or other components. The voltage across every component in the circuit is zero. No part of the circuit stores or dissipates any energy. In short, the circuit doesn't work.
Can you use a 15amp outlet on a 20amp circuit?
No. You aren't allowed to install a device rated greater than the circuit is rated.The 20 amp receptacle would allow you to plug in 20 amp loads (which is why it is different than a 15 amp receptacle), and plugging a 20 amp load into a 15 amp circuit would cause an overload and the 15 amp circuit breaker would trip.ADDITIONThis may still be open for discussion. According an electrician from RKO Electric, you can in fact install a 20 Amp GFCI receptacle on a 15 Amp breaker. Apparently, the breaker will trip well before the receptacle is able to pull 20 Amps of current into the line. Please see the following link from another website: http://en.allexperts.com/q/Electrical-Wiring-Home-1734/20-amp-GFCI-outlets.htm2003 NEC Code Book says:210-21(b)(1), p.70-42: A single receptacle on an individual branch circuit shall have an ampere rating of not less than that of the branch circuit. To me this indicates that if there's only one receptacle on the circuit, you can't have an outlet rated for less than the circuit, but it neither mentions nor prohibits oversizing the receptacle.210-21(3), p.70-42: Where connected to a branch circuit supplying two or more receptacles or outlets, receptacle ratings shall conform to the values listed in table 210-21(b)(3)... which says: 15amp circuit, not over15amp receptacle (
In what type of circuit does electricity travel when it does work?
Electricity travels in a closed circuit when it does work.
Is it necessary to ground an outlet?
If the receptacle has a ground terminal (green screw) and has three prongs, you must connect a ground wire if it is a new installation. There is one exception to this: if the three prong receptacle is fed from the LOAD side of a GFCI receptacle, it is not required to have a grounding conductor. This is because the receptacle is considered to be protected by the GFCI's function. In addition the GFCI itself is not required to have a ground connected. In these cases the receptacle needs to be labeled "no equipment ground" on the wallplate. If this is existing, you are usually not required to correct things that were not originally done to code. However a three prong receptacle should not be used as such if it does not have a grounding conductor connected. This would lead to a false sense of grounding and safety.
How can all breakers be live and outlets not work?
The very first outlet in the circuit has a break, probably where the wires enter the receptacle.
What is wrong if you installed a gfci in the bathroom according to instructions and when the test button is pushed the lamp plugged into the adjacent bedroom socket goes off?
The "TEST" button is there for you to check the GFCI is operating correctly. When you test the GFCI using its Test button it should trip to break the circuit. Then anything connected to that circuit will have no power. It sounds like the light in the other room is wired to the same circuit as the one you are working on, so, if the GFCI is tripped - such as when you press the Test button - no outlet in that circuit will be able to work until you reset the GFCI using its "RESET" button.If what happens is as was just described then your GFCI is working as it was designed to do. If you are talking about a GFCI receptacle, and wired the receptacle as it shows you how to on the instruction sheet, then everything down stream from the receptacle is protected, along with the actual receptacle that you just installed. The bottom set of terminals on the receptacle that states the word "load", is where the wires leaving the receptacle box should be connected to. Incoming power to the top terminals of the receptacle outgoing power to the next receptacle to the bottom terminals. This allows the GFCI receptacle to protect every other receptacle that is connected down stream on that circuit. If you check closely to the other receptacles that are connected, you will find that they also will be off when you push the test button. ----- 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.

What cause other than circuit breakers which are okay would result in electricity failure?
Most commonly, a loss of circuit continuity by: A) Disconnected phase wire. B) Disconnected neutral wire. These wires can become disconnected or loose when jarring faulty receptacles, wire nut connections, etc. The way we usually troubleshoot these issues is to attempt to check each receptacle in sequence. The circuit is broken when we get to the first receptacle that does not work. The problem usually lies in the actual receptacle not working, or the working one immediately previous to the faulty one.
How do you repair short circuit when all appliances are tested to work properly?
If the appliances all test out and are found to have no short circuits in them then the next step is to check the supply conductors that feed the appliances. This can be easily done by unplugging the appliances and turn on its circuit breaker. When voltage to the appliance circuit causes the breaker to trip. this is the circuit with a fault on it. The most likely place is at the receptacle where the appliance plugs into the power supply. Turn the circuit off at the breaker and inspect the receptacle. If it looks suspicious change it out with a new one.

Does the code state how many receptacles are allowed on a 20 amp circuit?
Answer for USA, Canada and countries running a 60 Hz supply service.Allow for 1 amp per receptacle and then load the circuit to 80% of maximum.In the US and in every building except homes, code limits you to 13 receptacles per 20 amp circuit. In a home there is no limit because it is assumed that even if you put a receptacle on every stud, you couldn't possibly use them all.Further informationIn the United States in non-dwellings a circuit is limited to the number of receptacles a circuit can handle, calculating 180watts per duplex. This places a 13 receptacle limit on 20 amp / 120v circuits and a 10 receptacle limit on 15 amp / 120v circuits.In dwellings there is no limit on the number of receptacles that may be placed on one circuit since it is highly improbable that you could overload a residential circuit under normal circumstances.In dwelling kitchens, while there is still no limit in the number of receptacles, there is a requirement that counter tops be served by AT LEAST 2 SMALL APPLIANCE CIRCUITS RATED 20 AMPS.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.
Why does electric plugs in the wall not work when light switch is on?
Some custom homes were wired with with the receptacles that were switched. The receptacle was in a circuit with a switch controlling the the voltage to the receptacle. These circuits were mostly installed in living rooms. Table lamps were plugged into them so that when a person comes into the room, one switch would turn all of the table lamps. It could be that this switch has been replaced and installed up side down. So that when the switch was turned to the up position it was really turning the receptacle circuit off.
How do you convert a 120V receptacle to a 240V receptacle for a European stereo system that uses 230V if the Stereo has no toggle switch to 110V like some units on the market?
You can't "convert" a 120V receptacle into a 240V receptacle.A proper new 240V branch circuit complete with correctly sized circuit breakers, wiring and socket outlet is required.For more information see the Related Question shown below.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.
Why would only one plug-in work in a two plug-in outlet?
Two reasons. In older wiring or possibly new depending on the region, it was common place to split a receptacle especially in kitchens so that the top half was on one circuit and one was on the other. You may have a tripped breaker. Otherwise, the receptacle was cut to be a split receptacle and never wired that way. If you feel safe doing so, pull the receptacle out of the wall with the POWER OFF. Look at the sides where the wires are screwed down and see if the metal tab that runs between the two screw per side is still intact. If its not and you want the receptacle on a single circuit, replace the receptacle, but this time, don't cut the tab.
How do you wire a remote switch to a socket outlet with no switch?
You must route a wire 12/2 or 14/2 to the receptacle from the switch in order for the switch to break the circuit. Always switch the black wire at the receptacle, not the white (neutral). 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.
What is the proper way to test a receptacle?
The simplest way to test a receptacle is to use a plug-in type receptacle tester. This tester indicates either proper operation or common miswirings of the receptacle. If the receptacle is a GFCI, there is a special type of plug-in tester that has a GFCI trip button on top. This tester indicates the same things as the other one. In addition, you can press the test button to create a small ground fault, which will trip a properly operating GFCI. ---- IF YOU'RE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.If you do any work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work and always use a meter or voltage indicator to insure the circuit is, in fact, de-energized.
