http://www.cooperindustries.com/con...ntal/pv-fuses/solar-pv-fuse-14x51mm.htmlBussman shows 10,000 Amps as the interrupting rating. Never forget: PV cells saturate current flow with a bolted short at much lower levels than rotary induction devices. 15, 20, 25 & 32A Notably, these fuses are designed towards the European standard; hence the 32A type.

I have a little question.
Has anything in the box actually ignited?
Sure it looks pretty black in there, but I'm wondering if that isn't because of transmitted smoke/heat that may have come in through one of the conduits.

Trumpy:
I have no details/info that is 'firm'.
It appeared that there was some damage in one combiner box that was not soot/heat, but meltdown. An adjacent box looked like transmitted heat/smoke/soot. Keep in mind I am not the forensic party that is looking into this.
Most of the damaged area has been removed, grid identified, boxed up & transported to an interior location to be investigated. Could ba a long haul for an answer.

Littlefuse KLKD-15 on another jobsite is 100K AIC for AC and 50K AIC for DC at 600 volts.
I have not been back to the problem site yet, but probably by middle of next week.

I'm getting the gut feeling that either it's going to be a long time, or kept hush-hush as to a cause.
Can't share what I don't know.

Just a bump & update.
This array is now replaced and requested a inspection be scheduled.
No cause has been mentioned to me as of today, although there have been a lot of comments.
Coincidently, there was a large fire in an adjacent Twp yesterday (Mon), ao a large whse bldg, that also has a solar panel install. The cause is not determined, either a roof fire that ignited the panels, or a panel fire that ignited the roof.
The fire chief of that Twp only heard of the fire in this thread about an hour after his fire.

Thanks for the follow up Hotline. Any determination of cause should be shared with the industry for all to learn I would hope. I know NJ had a solar boom for awhile there and I would think that some installations were not done properly. We have a solar boom here in Mass now.
