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.
- Since the entire sub panel is protected, do I need any GFCI protection in these two lines, or is the sub panel protection good enough?
- 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...
