Simplest way to do it and probably the best is to find the wire that goes into the fuse pannel and set it up so its 120v, u can either tap into an existing 120v fuse or u can pick one up at homedepot and wire up a new one. Since your swapping the voltage at the source your likely to have the best results. Then you can buy a 120v wall socket and wire that up. I never liked the idea of using adapters and such since your going to be running a decent amount of power. You can use the wiring that is already in place. It's pretty strait forward, if u have any problems do a search on how to wire a new fuse in the panel and the wall socket should come with instructions if u dont know how to do it already, worse case have some one do it for you.
JackdaWack Reviewed by JackdaWack on . How should I convert 220 volt to 110? After many delays, we're finally making progress on our new grow room. The framing is just about done and soon we'll be ready to wire it. We have an un-used 220 volt outlet next to the new room. We'd like to convert this to two seperate 110 volt outlets so we can run the window Air Conditioner on one and lighting/fans on the other. A quick search on-line showed that we can either have it re-wired into two 110 circuits or buy an adapter. Durn if we can't find the adapter. Everything Rating: 5
