What gauge wire should I use to power a new receptacle at about 40' from the service-box with 30 amps (110v)?
Question:I just want to mount the receptacle box and run the wire, I assure you I'll have an electrician do the hookup, but just didn't want to go to the trouble and use too light of gauge wire.
Answers:
Not to be rude John but, according to article 310.16 of the National Electrical Code.you actually are going to need to run # 10 awg (american wire gauge). There are certain stipulations where #12 would work but trust me..being an electrician, you want to run #10's. Then for the romex, you would need to check with your local municipal electrical codes as to whether you can run romex or if it has to be in conduit. Hope this answers all your questions.
not being a electrician but able to do my own elect. work I would run 12-2 romex wire
For a 30 amp circuit you need at least number 10 gauge Copper. If using Aluminum you need to go a size bigger.
Jsparky is correct.
Hondu - you can't use aluminum wire for branch circuits, only for services and feeders. Please don't answer electrical questions that could lead people astray. It could be dangerous in some cases.
John - same thing. An over heated 12 ga wire can burn the house down. Your house is one thing but don't give advise that could burn someone else's down.
outdoor romax at 10 or 12 gauge wire would be sufficient
