GFCI Requirements
A GFCI (ground fault circuit interrupter) is a device that de- energizes a circuit when a current to ground exceeds a specified value that is less than that required to open the circuit breaker. GFCIs are intended to protect people from electric shocks and are usually required in wet or damp locations.
Installation in recreational vehicles may require GFCI protection of certain branch circuits. Consult all applicable codes.
Disconnect Devices
Each system requires a method of disconnecting the AC circuits. If the overcurrent protection device is a circuit breaker, it will also serve as the disconnect. If fuses are used, separate AC disconnect switches will be needed between the source and the fuses.

Distribution Panels
Some systems incorporate distribution panels both ahead of the |

inverter/charger (the AC source panel) and between the inverter/ |
| |
charger and the loads (the AC load panel). The AC source panel |
| |
includes a main circuit breaker, which serves as overcurrent |
| |
protection for the panel. Additional circuit breakers serve individual | only. | |
