I have a sub panel in my attached garage. It has a small heat pump/air
conditioner on it for a bonus room (I believe 50 amp) and a 50 amp
welder plug that rarely gets used.

I built a detached garage /shop with a 100 amp panel. Can I run my sub
panel in my detached garage to the sub panel in my attached garage?

I have the capability to attach it to the main panel but it would be
alot of work and would have to move 2 circuits.

It is possible to attach this to a sub panel but you still need to
keep the neutral isolated from ground. AND you will have to limit the
100 amp panel to a 50 amp breaker from the 50 amp subpanel. And maybe
not even 50 amp since your AHJ may have further limitations on the
current loading of your 100 amp panel.

Sorry for the confusion, both sub panels are 100 amp.


Look for a maximum branch circuit breaker size printed on the tag in the
panel you intend to feed from. That is the highest you can go. Guessing
that you can't go over 70 or 80 amps if you want to feed out of the 100 amp
garage panel.
