If you had a wall AC unit that ran on 240V and you got a new one that runs on 120V how do you change the wall receptacle outlet wiring to be able to run 120V instead of 240V and how about the breaker?

There are several factors: the outlet configuration and connection, the supply wiring, and the breaker. It has been suggested that: :The 240v gauge wire may be thicker than the 120 volt gauge. The 120 is 12 gauge and the 240 is probably at least 10 gauge. The wire itself will probably be okay. The outlet will have to be changed to a regular receptacle. The breaker for that circuit will have to changed to a 20 amp instead of the 30amp or so that it is now. I hope this helps you some. However, this ignores the fact that you can deliver twice as much power at 240v than 120v using the same rating wire and breakers. P= v x i; double the voltage, double the power for the same number of rated amperes. In any event, the cable into the breaker box will have to be disconnected from the two-pole breaker and the black (hot) wire connected to a single-pole breaker (say, 20A), and the neutral (white) wire connected to the neutral bar. There should also be a bare or green grounding wire connected to the grounding (or neutral) bar. The supply wiring must be at least 12 AWG or larger diameter (i.e., a lower number is larger diameter). In an ordinary north American receptacle, the black "hot" wire goes to the narrow slot, the white "neutral" goes to the larger slot, and the bare "grounding" wire goes to the third prong, often via the green screw marked "ground". Local code may dictate exactly how grounding connections are made (i.e., directly from the cable or with green pigtail from metal outlet box connected to the supply ground and the device ground). If possible, install a GFCI for added safety. Needless to say, any necessary rewiring of breakers and outlets should be done carefully by a qualified electrician, and you may need a permit, if not an inspection. It is also possible that someone illegally connected more than one outlet to the same circuit, so you should make sure there are none before any conversion project is undertaken, and account for any "extra" wires in the outlet box.

If your wall receptacle has tripped but not at the circuit breaker how can this problem be repaired?
If it's a GFCI receptacle and the button is not resetting then change the GFCI outlet.
Can you wire an electric kiln into an electric stove outlet with a NEMA 14-50R recepticle and a 40A breaker?
Yes. Since you want your breaker to be less than the maximum rating of the receptacle this would be fine.
How do you find the circuit breaker switch that controls a damaged outlet?
If the damaged receptacle faulted the breaker would have tripped. All that needs to be done is turn the breaker to the full off position. This will take the breaker out of the trip position and the circuit is truly off. It should not be hard to find the faulted receptacle as it will have some major damage to it and that is what made it short out in the first place. Change it out for a new one and test the circuit by plugging a lamp into it to confirm that the wiring was done properly. When removing the faulted receptacle check the wire colours and positions and install the new one with the exactly the same wire position configuration. If the damaged receptacle is just worn out and they do wear out, plug a light fixture into the worn receptacle. With the lamp turned on start switching the individual breakers off in the distribution panel one at a time. Just switch the breaker off and on and see if the lamp goes out and comes back on. You will probably need help with this part if you can not see the lamp from the distribution panel. When you locate the breaker that controls the lamp, leave it off and change out the receptacle just as they were connected to the old worn out one.
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.
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.
If your wall receptacle has tripped but not at the circuit breaker how can this problem be repaired?
If it's a GFCI receptacle and the button is not resetting then change the GFCI outlet.
Do you need a gfci outlet if you have a gfci breaker?
Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
EXPLAIN WHAT WIRES DO IN A RECEPTACLE?
Wires bring the voltage source to the junction box of the receptacle. At this point they are terminated under the screws of the receptacle. With the receptacle screwed to the junction box and the cover plate installed the outlet is ready to be used. The last thing to do is turn the breaker back on to energize the receptacle.
Can you wire an electric kiln into an electric stove outlet with a NEMA 14-50R recepticle and a 40A breaker?
Yes. Since you want your breaker to be less than the maximum rating of the receptacle this would be fine.
What if you did get paint inside an electrical outlet inside the slot and that outlet is no longer working?
The simple fix is turn the power to the receptacle off, change the receptacle out for a new one. Re energize the circuit and you are good to go.
Why would plugging in an AC unit in a wall receptacle cause the fuse to blow or breaker to trip?
Is the receptacle a 110 or a 220 outlet? If it's a 110, it needs to be a 220. Are there other appliances, lights, etc. wired on the same outlet? If so, you may have to re-wire so that no other appliances, lights, etc. are wired into the same breaker. Usually the larger appliances such as air conditioners, central heat systems are wired to a separate breaker or fuse.

How can you determine if you have 110 or 220 volts?
Most residential service in USA has both. In the USA 110 to 120 volts is a given and it would be very unusual not to have 220 to 240 volts. It can be easily tested at main panel with a volt meter. Or as an alternative call your power company.
How can you wire a 110V plug outlet from a 240V plug outlet not speaking of a converter but actually changing the plug outlet so that there are no long term effects on the 120V appliance?
Assuming the wiring to the outlet has 2 loads and one neutral, isolate one load from the outlet and use the neutral as the common. be sure to ground from the receptacle to your conduit or ground lead. You should also replace the corresponding breaker with a 120 volt single breaker.
How do you change a 110 socket outlet into a 210 socket outlet?
You probably mean to change it to a 240 V outlet... either case, you'll need to run a new wire and install a new breaker.
Can you change outlet to fit old 3 prong outlet?

Can I replace a 50 amp 240v dryer outlet with a std 15 amp 240 volt outlet?
Theoretically yes if you remove the two pole 50 amp breaker and replace it with a 2 pole 15 amp breaker. This has to be done because the new receptacle is only rated at 15 amps and can not be protected by a breaker any larger than 15 amps.Physically this is not going to happen due to the fact that you will not be able to connect the existing #6 conductor, which fed the 50 amp dryer receptacle, under the terminals of the new 2 pole 15 amp breaker.
