I am not going to name names or firms on this one to protect the guilty, but
recently I was called in to commission two different newly constructed bank
buildings for a major bank that I am sure you all would know, that recently
installed two large solar pv systems. After commissioning the interio
I just sent a post about people not understanding the dangers of fire in the
array strings between the modules and before the combiner because its high
voltage DC and there are no fuses or circuit breakers to shut down the power
source (at least not until the next code requires arc-fault sensing!).

Most local codes, have granted a delay on implementing arc fault
protection. Also, the code only requires series faults to be cleared.

I mentioned this because arc fault is already in the 2011 NEC whether it
is adopted or not.
