Charge rate will be what ever "house battery" requires to equalize its self with starter battery.... Current inrush may be as high as 40-50 amps initially and reduce its self to mere trickle as batteries equalize, and depends on how much "house battery" is discharged.... MY Chevy PU has 10 gauge wire from fuse block and 40 amp fuse in line to 7 pin connector... Only negative to Chevys concept to put 12 volt power to 7 pin connector is there is no relay in circuit to protect start battery from draining along with "house battery"....

I have a waeco 12v fridge, the compressor won't start if it senses low voltage. With the battery fully charged, it wouldn't start with 12g wire because the voltage dropped . with 10g it works fine. Charging the battery works the same way, the charge line has to carry the amperage at a voltage above the TD battery, or charging won't happen.
