Introduction
The ACCB connects to the AC side of a Sine Wave Plus inverter and
accepts AC conduit runs. It protects the cable connections to the inverter
and provides an inverter bypass (for a single AC source) and AC
disconnect breakers.
Additional circuit breakers may be added to the ACCB. Use Square D,
Type QOU, DIN rail mounted breakers which can be readily purchased
from most electrical suppliers.
Square D filler plates (QOFP) may be used to refill a knockout panel if
the knockout is no longer used or removed in error.
The ACCB comes pre-wired for connection to a Sine Wave Plus inverter;
You must provide wires for connection from the AC distribution panel
and from a generator and/or utility to the ACCB. This guide provides
instructions for installing additional circuit breakers into the ACCB and
for connecting the ACCB to the inverter and other system components
(i.e., utility panel, AC distribution panel, grounding, and generator).
