Installing PV and AC Circuit Breakers and GFDI

Figure 19

Circuit Breakers

To mount circuit breakers:

1.

It may be necessary to remove the knockout from the
location where the circuit breaker is to be placed to
make room for the circuit breaker to be installed. Be
sure to remove any debris that may occur from
removing the knockout.

2.

Place each circuit breaker behind the premounted
rail. Center the device so that the raised area around
the switch protrudes through the bracket. It may be
necessary to hold the device in place by hand.

2.

When the circuit breaker is in place, insert the screws
included with each breaker through the holes in the
mounting rail.

3.

Tighten the screws until secure, but do not
over-tighten.

NOTES
 Although there are no specific designations, the upper end of the mounting rail is generally used for AC

devices (including the maintenance bypass). The lower end is generally used for DC devices, including the
GFDI. The preassembled GSLC models follow this convention.

 A PV ground-fault device may be required. The OutBack GFDI is pre-installed on some models. With other

models it can be purchased separately for manual installation. (See page 11.) The GFDI mounts the same
way as other circuit breakers. Once mounted, see page 27 and the GFDI manual for wiring instructions.
(Note that the GFCI usually requires multiple rail slots.)

 Some installations may require an AC maintenance bypass. This is referred to as the Input-Output Bypass or

IOB. The bypass comes prewired for a single Radian inverter in some GSLC versions. It can also be purchased
separately. See page 29 and the GS-IOB manual for mounting and wiring instructions.
