Jesse,
You may want to check out the new(ish) line from GE and Eaton. Both have 600VDC listings, Eaton's newer line has 3 and 6 pole versions available. I have the Eaton disconnects specified for an upcoming job but I haven't used either as of yet. http://www.geindustrial.com/cwc/Dispatcher?REQUEST=PRODUCTS <http://www.geindustrial.com/cwc/Dispatcher?REQUEST=PRODUCTS&pnlid=5&famid=3 9&catid=62&id=Solar-SD> &pnlid=5&famid=39&catid=62&id=Solar-SD http://www.eaton.com/Eaton/ProductsServices/Electrical/ProductsandServices/E lectricalDistribution/SwitchesandDisconnects/SolarDisconnects/index.htm Ryan From: [email protected] [mailto:[email protected]] On Behalf Of Jesse Dahl Sent: Friday, August 24, 2012 6:43 PM To: RE-wrenches Subject: [RE-wrenches] Disconnets Hello, I've been having a long conversation with a local guy about disconnects that are usable in DC PV circuits. From what I have seen, GE, Eaton... they are usable up to the 250VDC it has listed on the labels, or more if poles are wired in series. The squared D 600Vac/dc is self tested to 600VDC/pole. The disconnects in question are not the "solar disconnects" on the market now. What are people using for the GDI systems? I seem to think that if if says 250VDC on the label, that is its rating unless you wire pole in series and the manufacturer has literature saying that that is acceptable. Thoughts on the square D self listing? Jesse
