Ac Power Distribution Panel
Branch rated over current protection for the AC output circuit is to be provided at the time of
installation.
A branch circuit at the ac power distribution panel can be used to supply the ac input to the
inverter for bypass operation. This circuit should use a 15-amp or 20-amp circuit breaker. The ac
output from the inverter can feed a separate section in the same panel, such as the WF-7923-S
or WF-7925-S, to supply multiple circuits that can be powered by the inverter. Alternatively, a
second panel can be used for the inverter-powered circuit distribution, if more than one circuit is
to be powered by the inverter. Refer to Figure 6 for a wiring example.
The wire gauge needed for the ac wiring should follow NEC requirements for ampacity and circuit
protection. Strain relief should be provided near the inverter for the ac cables.
