I'm definitely interested in being involved too. I really respect how difficult the language crafting can be, and the frustration to have certain intent be misconstrued by an AHJ some where else later. R.Ray Walters CTO, Solarray, Inc Nabcep Certified PV Installer, Licensed Master Electrician

Thanks for the correction on that sedona fire Bill; I had only seen the incorrect fire dept report. I wish there was a clearinghouse for information on RE incidents and close calls as they are all teachable moments for both RE professionals and firefighters. I ditto the need for more NEC guidance

William and John, A "320" as it is affectionately called is a 400-amp panel with a 320-amp continuous duty. This is identical to two 200-amp panels that each has a 160-amp continuous duty-that we put 40-amp breakers into on a routine basis. The "busbars" are rated for 200-amps each, just like a

I would think this would be fine, so maybe I am missing the issue. Does CA have a state-specific rule on this? What you're asking is whether you can safely install a 40A inverter circuit in each of your interior [200-225A] panelboards fed from this meter main, right? This is two separate load-s

Has anyone tried to connect one 40 amp inverter output circuit to each of the two breakers on a 2 x 200AMP single meter main panel in California? This would yield 80 amps of solar feed into the panel and the meter using two discreet circuits. It would stay under the 120% rule for each 200 amp

Jeffrey and Ray, Batteries can off-gas hydrogen-sulfide gas when under heavy charge or overcharge. It is the nasty rotten egg smelling gas. Definitely not to be inhaled since when it hits your lungs it turns back into sulfuric acid. To address Ray’s point, the new 690.12 regulation that has

Ray-- What poisonous fumes do lead-acid batteries off-gas? I know they off-gas hydrogen, which can be an explosion hazard -- but hydrogen isn't poisonous. Or were you thinking about a different type of battery. Jeffrey Quackenbush On Thursday, January 23, 2014 8:19 PM, Ray Walters wrote:

I must jump on my soap box, as I have so many time in the past, and follow up Glenn's comment here. We worry so much about details of PV arrays, while batteries are serious safety hazards that no one (including the NEC) ever wants to address. Not only can they not be de-energized, they have a

"They can safely shut down any electrical system in a building—except for PV systems." Not completely true, as batteries are stored energy systems and while they may be disconnected, are still energized regardless of the state of other systems. -Original Message- From: "David Brearley"
