Neither Tony or I suggested making a 120v circuit from the two wire 240v line using the ground as the neutral. Yes you can run three conductor Romex and have a 120v and 240v outlet but I do not see this as a good plan as it could easily exceed 20 amps on one leg. Upgrading to higher amperage circuit and you'll exceed the amperage rating for a standard 120v outlet. Two separate circuits are much easier to manage.

The ground wire should never carry current. An inspector would never approve it, and if you value your insurance coverage, don't try it - it will be found after the fire! 73, Don W3FPR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
