Wrenches,
Like a few other of the most progressive states in terms of renewables, New
Mexico has an involved state government. Ryan Helton of our state's Energy
Conservation and Management Division (handles RE) sent this request out
today. I'm forwarding it to the list because it seems to be a per

I think you are right, the weakest link in the chain was a compression
fitting. Maybe one that was not properly tightened. An EMT connector
will thread right into a RMC coupling and it doesn't look like it would
interfere with the expansion joint motion, so I still think the

Kent,
I looked at the photo of that expansion coupling and initially thought, "That'll
work". But if the conduit was RMC OR IMC all the joints would have been
THREADED into couplings, and even if by mistake they were not wrench tight, they

Thanks for posting the info on the Target fire. We all need to learn
some lessons from it. I'm sure that it is going to lead to changes in

buildings with very large flat roofs. The problem is the structural engineer
says the roofs can only support less than 4 pounds per square foot
additional load. Penetrations are a secondary issue, but weight is a

The DC disco coming off the PV breaker box might be a good idea. With this
case showing that. We know that we can open the box and kill all the
breakers but few others do or would have the the time and thought to do it

Would it be a 1 armed bandit or would a big dc rated breaker

Thanks for the analysis report, hopefully, we can all benefit from this
experience. Attention to detail matters.
What impressed me was the "timely" report, barely a month since the incident.
Not to say the defense lawyers won't find another paid expert to
For the record, another equivalent of the Ilsco and Burndy lugs already
