[RE-wrenches] DC wire sizing

[Erika M. Weliczko]

To my understanding the 156% on PV source and output circuits is related to
the ability of PV to deliver more than rated and be continuous.

Therefore, the wire has to be able to carry this current, so now the
temperature and fill corrections are applied to find the wire capable of the
156%.

 

I am in a debate where the question is why correct for temp and fill on 156%
of ISC and spend all that extra money when the normal operating is at Imp.
Or why correct the 156% but why not correct the Isc or Imp.

 

I am going to stick to the fact that the circuit has to carry the 156% under
all conditions.

Thoughts?
