Answer for USA, Canada and countries running a 60 Hz supply serviceCommon 120 volt residential outlets have a wire size of 14 or 12 gage. In general an outlet is made for a wide range of wire sizes. Each of the outlets has a different arrangement of pin slots so that only the correct plug can fit into the matching outlet. The outlets are given names by National Electrical Manufacturers Association (NEMA).

<><><>

NEC or NFPA 70

residential

duplex receptacle circuits SHALL be 20A ( #12)

kitchens SHALL have a minimum of 2 20A circuits

each receptacle SHALL be considered a 350VA load for load calculations

(more than 6 receptacles on one circuit and you better add another circuit)

fixed appliances Shall have their own circuit

Stove, oven, range, garbage disposal, refrigerator,freezer

are sometimes built in and sometimes have a plug and cord if built in

its not good karma to put a toaster on top of the refrigerator and plug it in the same socket.

laundry appliances ( Washer dryer ) have their own circuits

(always considered fixed appliances)

lighting circuits may be 15a depending on lighting load

--------------<><>---------------

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.

If you do this 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.

Usualy 14 guage if you're using a 15 amp breaker. If you use a 20 amp breaker you can use a 12 guage wire.

Your electric stove has a 3 prong plug your new stove has a 4 prong stove you bought a new 4 prong outlet but on your old outlet it oly has 3 wires no ground wire how do you ground it?

Look in the back of the range receptacle box that is in the wall. The three wires coming in should have a bare ground wire in the cable set. It wasn't brought to the receptacle because there was no place for it on the three wire receptacle If you find it back there under a screw terminal just add another short piece of wire under the screw and then connect the other end of the short wire to the new ground terminal on the new four position receptacle The wire should be equal in size to the size of the wire that exists around the ground terminal now. If the house is so old that the range cable did not have a ground wire in it the code allows a separate green ground #10 wire to be taken from the breaker panel box to the existing range receptacle This wire is to be bonded on each end. At the panel end to the ground buss and at the receptacle end around the ground screw at the back of the box unbroken and then to the new four position receptacle ground lug.


Is American Wire Gauge a standard used to describe the size of a wire?

Yes. It is abbreviated as AWG. For example, in residential wiring the size wire to use on a 15 Amp circuit would be 14 gauge or 14 AWG.


Is there an adapter for a NEMA 14-30 male plug to a NEMA 10-30 female receptacle?

No there is no adapter. Change your old dryer receptacle NEMA 10-30 to a new NEMA 14-30. This will allow you to plug the new dryer cord into the old wiring.Answer for USA, Canada and countries running a 60 Hz supply service.Range receptacle three to fourLook in the back of the dryer receptacle box that is in the wall.

How do you rewire a 220 volt receptacle to produce 110 volts?

A 220 volt receptacle is a receptacle which has 2 wires carrying 110 volts...it has two "hot" wires at 110 and a neutral or common leg which has no voltage. A 110 volt receptacle is a receptacle which has 1 wire which carries 110 volts and a common wire. The wiring in the USA is almost standardized now to where the two "hot" (carrying 110 volts) wires are colored black and red, and the common or neutral is white. To change a receptacle to 110 volts..you remove the red or black wire from the old receptacle and wire nut it off...leaving the other red or black to attach to the new receptacle (right side of receptacle usually, looking at it from the grounding hole on the receptacle ON THE BOTTOM). You then connect the white wire to the left side of the receptacle. This will provide only 110 volts now. If the wires are not black, red, and white..they may be black, black, and white. In most cases, the white wire is always the neutral or common wire. When in doubt, buy a voltmeter and check each wire to the metal box in the wall...the wires carrying the 110 volts will usually read 110 on the voltmeter (or 115, 118..etc). Good luck!


Do you need 15A MCB for 15A socket outlet?

A 15 amp circuit breaker is used to protect a # 14 copper wire which is the minimum size wire that can be connected to a 15 amp receptacle.

How do you add a 240 volt receptacle to 100 amp supply?

The 240 volt receptacle has to have an amperage rating. It is this rating that governs the wire size and breaker size to feed the circuit. The new two pole breaker will be inserted in the 100 amp distribution if space is available and connected to the new wiring that terminates at the new receptacle.

Which one of the folling types of wire can be used with the pressure terminals of a duplex receptacle?

The types of wire you can use on duplex receptacle with pressure terminal are labeled on the receptacle, next to the holes. AWG 14 and AWG 12 are the typical wire gauges used in this application.

Can you use one length of 3-wire cable to provide electricity to 2 separate circuits?

In countries that use a single phase split secondary service you can. In modern homes this is the type of circuitry that is used for kitchen split receptacles. On the receptacle the tie bar is removed from the "hot" side of the receptacle. A red wire of the three wire cable is placed on the upper terminal of the receptacle. A black wire of the three wire cable is placed on the lower terminal of the receptacle. The white wire is placed on the opposite side of the receptacle under the silver coloured screw. This will give you a full 15 amps capacity on the top portion of the receptacle and a full 15 amp capacity on the bottom half of the receptacle.

How do you wire a 4 prong dryer cord to a 3 wire receptacle?

Using a red wire nut hook the 3 wires (of the same color) together with a short piece of wire of the same color. You now have 4 wires tied together. Now take the other end of the short wire and attach it to the outlet on the correct screw Do the same with the other 2 wires Please keep in mind to make sure the wire nut has securely fastened the wires. Loose connections cause heat which cause fire If you do not completely understand this answer please contact a qualified electrician


What do you do with the green wire from a light if the receptacle doesn't have one?

Green typically represents a ground so you would connect to the bare wire at receptacle or look for a green headed screw.


Can you change outlet to fit old 3 prong outlet?

An old 2 hole receptacle can be changed to a 3 hole receptacle that will accept a 3 prong plug, provided a ground wire is available at the box and connected to the ground (green) lug on the new receptacle. A 2 hole receptacle has a hot and neutral wire, while a 3 hole receptacle will require a ground wire connection -- in addition to the hot and neutral wires.
