I talked/emailed with Forrest about this some time ago, but my memory is
fuzzy.
I think what I recall is that each shunt can go over the rated amps by
some percentage, but I can't remember what that was. I think it
something like 110% or 120% or somewhere in that neighborhood. Don't
quote me on that.
Most of our sites are less than 2 amps in total draw; maybe 100 watts or
less on a 48VDC system.
However, some of the battery chargers that we use can theoretically
charge at up to 15 amps or in that neighborhood. So I would have
serious concerns about using a 10 amp shunt on something that could be
running at 15 amps.

Guys,
Its been a few years since I looked at the shunts that we use. So, I
have dumb questions on which of Forrest�s shunts to use �
If a tower typically draws 3 to 4 AMPs� we should use a 5 AMP shunt?
And, a tower that even sometimes draws over 5 AMPs, we should use a 10
AMP shunt?
