Installation

The following illustration shows the complete wiring for the ACCB-L-L1, TX Autotransformer, and a SW Plus Inverter for a Step-down Configuration to use a 240 Vac-Only Generator. This configuration uses the ACCB-L-L1 as the sub panel.

Note: Because there is only one circuit breaker installed (other than the AC Bypass Switch), the output for the ACCB-L doesn’t not need to be connected to the L1 HOT Bus Bar. It can be connected to the line side of the field-installed circuit breaker.
