leg one, leg two question

[jvicars4]

I am trying to understand how leg one and leg two work in the coach. I
looked at the guages and leg one and leg two both have 120plus voltages
but I only notice amps being used on leg one when under normal
operation (one air, chargers). I have not noticed leg two showing amp
draw. I would expect some of the items on the coach would be on leg two
but I have not seen it drawing amps. Please let me know what to
expect. Thanks.
