A couple of notes
You DID get the CMC 175 amp BLUE Spare that was in the Bottom of the
PINK shipping box?
I try like heck to ship chargers with the AMPS knob set to straight up
gives 1/2 the max current read from the AC line. So straight up will
suck 25 amps +- .5 amps. This should help in the How much am I sucking
question?
Yea I bet The 50s will suck 5 amps more than the beakers are rated for
and nobody will notice. I have yet to open the 50 amp breakers here,
except for those... Ummm testing incidents. I never opened a breaker at
Woodburn, I pulled full amps for LONG time chunks.
Wanna Know how TO make the open???? Ummm better not.
