Let's put this in monetary terms. 100 ft of 12/2 with ground is $56 at Home Depot. 100 ft of 10/3 with ground is $138.
If you pay an electrician to do the work, the difference won't be 10% of the bill. If you do it yourself, following code and getting it signed off by an electrician and inspected of course so your insurance won't deny coverage, and you value your time, and there is a chance you may want extra 120 V in the future, it will save hours of replacing it later. I would go with the 10/3 with ground, but that's just me. When you sell your house and the next owner wants to put something else there, you may get more for the property. For example, the previous owner of our house installed a 20A RV power outlet. And yes, it came from one side of a 20A 240V feed with a neutral and ground. That was worth hundreds more to us. I would still put in 20A breakers. They protect the wires and if all you need is 20A for the load, it seems sensible to be more protective. I have heard of inspectors seeing 20A breakers and AWG10 wire and questioning it, but it seems you could explain it was done for an extra safety factor, etc. Breakers are quick to change. Good luck with whatever you do. 73, Mark W7MLG ______________________________________________________________ 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]
