[RE-wrenches] Battery Conductors and the NEC

[Sam Haraldson]

Are your ears burning, Chris?  Because I was not more than one hour ago
standing in front of a newly installed system that is tripping 250A
breakers.  As we were trying to determine the best way to replace the
single 250 with a pair of 175s combed together but maintaining the single
run of 4/0.  The manufacturer's ampacity spec would allow that and we have
a combination of free-air and well-ventilated raceway between the battery
and combiner which is giving us pause in how to best proceed.

Cheers,
Sam
