Have an electrician install a sub panel, with an appropriate breaker in the main panel so you don't burn your house down.

1 foot of good wire beats hell out of a mile of firehose.
Mississippi Steve Reviewed by Mississippi Steve 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
