Re: [RE-wrenches] Rooftop wiring methods between multiple subarrays

Hello guys... I believe (but I can be wrong) that the code is pretty clear on this. . No problem with the metal conduit. . Use bonding bushing on the ends (to be sure that the conduit is bonded) . No problem with the ground wire touching the conduit - in fact the b

William - I agree with you about a no-shortcuts and full workmanship plan of attack. That is how we will all stay in business and continue to make local scale PV a success. However, when we dissect the details of running between multiple array sections I still don't see a good solution. I'm gla

I deal with New Mexico/ Colorado/ Texas for my inland experience, and Hawaii/ Mexico for my coastal experience. Hawaii is hard core enough that many main service boxes are Stainless. New Mexico requires the wet loc fittings for EMT with the integrated plastic seals. We use our old stock of reg

Hi Ray - What coastal region or regions are you familiar with? I'm really only familiar with the San Francisco Bay Area but thoroughly painted EMT seems to hold up through the long haul even just a few blocks from the ocean. If it isn't painted the straps and fittings start rusting in less than

Wrenches, U.S. electricians have different rooftop wiring and conduit options that worked successfully before PV and work well with PV. The same holds true for Europe. I've seen bad and sloppy work on both sides of the pond. John Berdner and others familiar with European wiring practices and do

Colleagues, What are folks thoughts on how IMC conduit weathers near the coast? Is this an upgrade that might be a better alternative than plastic? Jeff C. Village Power Design EMT needs to be "pickled" with vinegar or acid, to get the paint to hold. I love it for inland work, but near t
