Garage outlets

In reply to GFCI Breakers by Mike on February 14th, 2000 03:29 PM [Go to top of thread]

Mike, the sub-panel referred to is much like your
main panel, but usually smaller, and with a smaller
ampacity. It makes sense to use a sub-panel if you
have to run several circuits that are a fair distance
from the main panel, or if you have a limited number
of breaker slots available.
If you want to go that way, you will need to get a
book and do some studying since there are a number
of details to be taken into account. (e-mail me if
you need a book recomendation).
The general purpose receptacles in the garage are
usually required to be GFCI protected. GFCI breakers
will do the job, but they are very expensive and
have a reletivly short life expectance compared to
regular breakers. If it were me I'd just make the
first outlet of each circuit a GFCI and use normal
breakers. If the first outlet is a GFCI, and if
subsequent breakers are connected to it's load side,
the whole circuit will be protected.
PS. When you get around to that compressor, keep in
mind that motor circuits are sized differently than
regular circuits, for instance, a true 5hp compressor
would require a dedicated 35 A. circuit breaker and
8 AWG NM cable.
