@ Matt
two meters, two coils
one on each leg
just add them together for the total
works for both 30 and 50 amp power
power will never be exactly the same on each leg
and you measure the power thru each hot leg
neutral NOT in the calculations
neutral only carries the 'difference' between the two hots when on 50a service
you have too measure both legs to get the amount of power used
on 30a neutral and hot are the same, but the load will be split between the two legs in the rv
i built a portable one with a 100a meter and 30a plugs
so i can monitor the generator with A/C loads
or 30amp shore
great for testing loads and measuring PF watts and voltage, have to calculate the VA using the other numbers, even counts KW hours
no this is NOT a K-A-W
this is a home built good for 100 amps and uses 30amp RV plugs
Designed to be plugged into shore power or generator
one could be built for 50amp, but i built this one for 30amp
mainly for generator use/monitor
PICTURES NOT TAKEN TODAY
they are from an earlier post about the meter build
