737NG TR1 and TR2

[KriVa]

Hi guys,

A pretty basic question from me this time:
During flight, do TR1 and TR2 carry the same amount of amps, or do they differ? I can't put my head around the FCOM 100%

And, as a little side question: Does the GND PWR setting on the Electric Panel have an Amp rating or not?

Thanks for taking the time to answer!
