Hi Allan;
I with you, I normally downsize the interconnects in parallel strings to 2/0,
but keep them the same as the main cables on anything that carries full
current, as Phil made clear.
On golf cart batteries for instance, two 4/0 parallel lugs won't fit under one
battery post, now that most
Peter, you're certainly barking up the right tree with thin-film or
amorphous solar products in a hot climate, although I have no direct
experience with the First Solar products. Amorphous silicon PV in general
suffers about half the temperature fade of crystalline PV products. This
often makes the
I would think the UL listing would means it s a safe tool to use for the
crimps. But with anything use common sense.

William,
I also have found your calculator to be a real timesaver.
Thank you.

I like the field description where you enter the current at "the end of the
cable run," as if that is different than the current anywhere else in the run!

Thanks Drake.
The original article was called Wire Sizing and Voltage Drop in Low
Voltage Power Systems". It was in two parts, in HP issues #13 and 14.
