I take what code requires as the minimum wire gauge. For shorter runs it's fine. But measure the run length, multiply by 2 (two wires) and calculate IR voltage drop. It's not a big expense when you're installing to use 10 instead of 12 awg if it would make a noticeable difference.
Seems like it wouldn't need to be said... but never let them cheap out and use aluminum wire. I actually had an electrician try that for a bigger gauge run. Fortunately I noticed before it was enclosed. Cut it out of the wall and left it coiled for him with a friendly :) note. 73 Josh W6XU ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
