I can imagine the conversation in the chat room: Reno: I wonder .... The administrator: Don't even think it! The other mods: We dare you!

If there's a main breaker rather than a main fuse I always thought the main is supposed to be slow enough never to trip in case of a short unless the branch circuit breaker fails (that's why type E main breakers in Germany are 15 times the cost of regular B or C branch circuit breakers).]]> Fri, 03 Jul 2009 12:21:10 MDT http://www.electrical-contractor.net/forums/ubbthreads.php/topics/187583/Re_shed_on_a_GFCI#Post187583 Posted by SteveFehr:
If you plan on putting any receptacles in the shed, it's going to have to have GFCI protection. The code does not require lighting circuits to be on GFCI, but it does not prohibit it, either. One point of considering I didn't see brought up is the exception in NEC that allows a 20A GFCI-protecte]]> Thu, 02 Jul 2009 11:40:55 MDT http://www.electrical-contractor.net/forums/ubbthreads.php/topics/187552/Re_13_Things#Post187552 Posted by Alan Belson:

Check out anything from Sandia National Laboritories. They have a "Handbooks of Recommended Design Practices" and reprints of many well written articles.

They do bless some totally off grid systems. I have a question open as we speak with the folks who certify systems asking why they won't encourage the pool pump system. It is the simplest PV system you can get. No batteries, no inverters, no grid ties. Just collectors spinning a motor when the su]]> Tue, 30 Jun 2009 01:10:55 MDT
