adding a 110 to a 220?

hi, I need to pull a 220 line for an air conditioner and I also needed a

110 line for a light that's 5 feet away from it all the walls are finished and it's an old house with the plaster and lath walls. I was wondering if i can make a splice at the 220 outlet and take the 110 from there because the panel box is far,(about 40 ft)away. can someone please help me? thanks in advance,

Sounds like a bad idea to me, simply because the A/C will probably be

30A (or more!) so you will have to maintain the wire size required by the breaker for everything connected to it. I'd just pull two separate cables and be done with it. 40' of 14/2 is not that expensive.

run 2 seperate cables, or use a close by supply for the light.....

You did not provide much information for anyone to give you precise instructions. Where is the electrical panel in relation to the air conditioner? Is the panel in the basement and the A/C on the second floor? Will the light be wall mounted or on the ceiling? Will the light have a wall switch?

Some older houses were built using balloon framing which allows a clear passage through the walls from the basement to the attic. Try pushing a fishtape up the wall from the basement to confirm this. There could be a brick or masonry firestop at the bottom, but you may be able to sneak past it. If it is not a concern another possibility is to run conduit up the outside of the house.

There was a detailed posting/discussion about cutting into wood lathe and plaster walls for electrical boxes in this newsgroup a few months ago. It provided good information and I recommend that you do a search to find it.

Connecting a 110 volt circuit off of a 220 A/C circuit is not an acceptable practice. Even if it was the light would dim every time the compressor kicked in.

"Every fall, when we turn off the breaker for the AC, the light goes dead. Honey, what's going on? Can't you fix that?"

the a/c wont have a nuetral, and its just a hokey hook up you should just pull another wire

first of all, the ac will have power all i got to do to achieve that is to use 12-3, and second, my whole point of asking was not to have to pull another wire. but thanks for your time anyways, good luck next time,

You could use a small transformer to get floating 110v from the 220 circuit w/o a neutral. Enough for a light bulb, anyway. The transformers get expensive pretty fast at higher volt-amp ratings.

Run 220v to the lamp and put the transformer in the lamp fixture, so someone doesn't think they can plug a coffeemaker or hairdryer into the transformer outlet.

You should not try and splice the line. The best thing to do is to run the 220 to the AC and the 110 to the light separately from the power box in your house. Pay attention to your amperage ratings too so you don't run a 30 amp line on 14 gauge wire.
