Sure, the fuse disconnect from the meter was replaced by circuit
breakers, but the sub panels themselves have no main, lugs only. So
the circuit goes from the main panel breaker to the sub lug only.
Just curious if the replacements subs need mains or main lugs are fine
as a replacement....
Thanks for the feedback.
