We recently ran a 10-3 line from our house panel to a sub panel in our
barn, using a 30-amp GFCI circuit breaker.
I have since run two separate 12-2 cable lines from the barn's sub
panel to outdoor outlets.
I was planning on putting in two 15-amp GFCI circuit breakers to
protect the lines. I realize I could also use GFCI outlets (putting
them first in line), but went with the breakers instead.
1. Since the entire sub panel is protected, do I need any GFCI
protection in these two lines, or is the sub panel protection good
2. Is there any issue with using GFCI breakers in a panel protected by
a GFCI breaker? In other words, since the main line to the barn's sub
panel is protected, can I use GFCI breakers in the barn's sub panel?
THANKS in advance...
