The UL listing is only good for 12 or 24 volts, the manufacturer listing carries no weight if the defecation hits the rotary oscillator. UL is the one that counts. If you're using an MPPT controller unless the panels are wired as single panels you can't use the QO breakers. I have always run

Who was the inverter manufacturer? Please respond off list, I just had to ask. I would have sent it off list but it came as a bounced message. Thanks, Bob From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Kurt Albershardt

The QO breaker I saw fail was a disconnect switch for an Air 303. The run from the battery bank was substantial, and the wire was number 10. At the time, I calculated the amperage available (I -V/R) and the short circuit current available was not close to the 5000 amp AIC of the breaker

HI Drake I don't know if this could apply to your situation, but I've seen the QO/QOU fail from debris getting into the breaker itself. Around here there are insects that deposit mud into small openings, like on those breakers. I've seen this cause the breakers to fail. jay peltz power On May

I've also seen failures/ nuisance tripping due to loose connections at the breaker. The heat then wreaks havoc on the breaker internals. R. Walters r...@solarray.com Solar Engineer On May 17, 2010, at 8:23 AM, jay peltz wrote: HI Drake I don't know if this could apply to your situation,

Quick poll- how many inspectors/utilities out there require the live on both sides label for AC Disconnects, even after you explain to them this only applies to DC disconnects? Even though it's inaccurate, I feel that it at least gives unqualified personnel pause before they open up a switch

I only use this signage, when its true. Gridtie inverters interrupt output in milliseconds, so I don't use it on AC. My understanding is that it does apply to array disconnects, as the inverter capacitors could still have a charge, that would render the live on both sides idea true on DC. I

Without any word, they have stopped taking orders.! Not only could they not fulfill an immediate need, they refused to even take a pretty nice order for future delivery. Who is still getting Kyocera? Whats the deal.? Are they dumping the small accounts?  If you are still doing business
