how are you wiring to get 110 Volts power out from 220 volts source?

Question

I want to get 110 v power out from a 220 v source

how to rewire the outlet in order to get a 110 VAC out from a 220 VAC source

Answer 1

You can only do this if there is a neutral inside the box as well. If there is then use either the black or the red with the neutral(white) cap the other unused wire, and wire in your new receptacle. But now you need to replace the two pole breaker in the panel with two single pole breakers. They are usually around $12 each. and make sure the neutral has been landed on the neutral bus bar.
I received your email and would like to further help but you need to confirm your email with yahoo or simply use my email address. Warning!!! If you are getting 278v to ground first off DONT use the ground, and second it sounds like you have an electrical problem on your hands. 277/480v is commercial and actually should be wires colored Brown,Orange, Yellow, and Grey as neutral. You mentioned an emergency light that would tell me that we are talking about commercial applications here. The good news is that commercial is generally designed for modifications and upgrading. Feel free to email me with further details.

Answer 2

the 220 will have 3 wires, white, black and maybe white with bllack streamer, or maybe another white wire, or red. Basically with 220, you are running 2 110 circuits through it, so you need to remove one of the 110 circuits. ENSURE you remove the source of power before beginning any electrical work, and tag the circuit or lock the box if it is distant from where you are working to ensure it is not energized by someone else. Now all you have to do it remove the dual breaker from the box, and get a 110 single pole breaker, run the white wire to the common side of the breaker, and run one of the black or white/other wires to the other side, and put a wire nut on the other unused wire, or install 2 110 breakers. once you hook it up, use a multimeter to ensure your really getting at least 108 volts out of the circut, then turn it off and continue with your installation.

Answer 3

get the plug that fits the 220 outlet and wire it with one hot one neutral and the ground leave off the second hot. On the other end wire a standard 110 female end as you normally would. Plug what ever you want into the 110 end and all is well. you do not need to mess with the wall outlet

Answer 4

If you put two wire that are 110 volts together they may add to 220 if they are 180 degrees out of phase. A typically house has two hot wires and a neutral the two hots are 180 degrees out of phase and add to 220 volts. The output of the CB's in slots 1,3,5 are from one phase and the CB's in slots 2,4,6 are from the other phase.If you take voltage from CB's 1 and 2 you'll have 220 volts limited by the smallest CB typically 15 amps. If you attempt to measure two outlet in your house the hots will not necessary be 220 the hots may actually be in phase. If the hots are out of phase you will have a 220 volt 15 amp.

Answer 5

You will have 4 wires in the box. ? you did turn off the power? 1 bare copper ground 1 white nuetural and then a black and a red . Just put some tape on one of those wires along with a wire nut. the black and the red are both hot, so the 2 of them make your 220, just cap on of them and connect a standard outlet and youll have 110.

Answer 6

find the wiring in the breaker box. Disconnect one leg and tie it to the neutral bar. Tie the other leg to a single pole breaker. Wa La. you now have 110 vac power.

Answer 7

you need a tester (set to measure 220v AC or higher) & a convenience outlet near a grounded metal (like a deepwell water pipe). place one of the probes on one line & the other on the grounded metal (use a length of wire properly connected if necessary). if you're lucky you'll get 110v on both lines with respect to ground, sometimes it's 120v on one & 90v on the other but if it's straight 220v on one & 0v then you have no choice but use a stepdown transformer.
