Installing Additional Breakers

If additional AC circuit breakers are to be installed for specific AC loads or a

generator disconnect, then install them per the manufacturer’s instructions on the

DIN Rail in the space to the left of the factory-installed AC Bypass Breaker. The

Long AC Conduit Box DIN Rail supports Square-D™, Type QOU, circuit

breakers.

To install additional Square-D™, Type QOU, circuit breakers in the Long

AC Conduit Box:

1. Remove the top cover as described on page 2–6.

2. Loosen the screw in the DIN Rail End Clamp and slide the clamp away from

the existing breaker.

3. Install the circuit breaker(s) on the DIN Rail to the right of the factory-

installed AC Bypass Switch. Be sure to align them to fit into the spaces made

by the knockouts that were removed on the top cover.

4. Slide the clamp tight against the last circuit breaker on the right and tighten

the screw to secure the clamp on the DIN Rail.

If creating an ACCB-L-L2 using the ACCB-L2-PCK add-on package, install the

second AC Bypass Switch to the right of the factory-installed AC Bypass Switch.

See the instructions provided with the package. Ensure the DIN Rail End clamp is

tight against the last breaker installed.
