AC Disconnect and Over-Current Protection Device

To meet CSA, UL, and electrical code requirements, and to protect system wiring, the AC inputs and outputs of the inverter/charger must be provided with over-current protection on both the AC input and output. This protection may be a circuit breaker or a fuse with a disconnect device (for simplicity the following refers to breakers). Refer to your applicable installation codes and the following requirements:

AC Input Protection

The breakers protecting the AC input of the Freedom SW 3000 must be approved for use on 120 VAC branch circuits, and must be located in each Line. The breakers must be rated as shown below:

•Split-phase input: No more than 30 amps max in each line.

•Dual input: The neutral current in a dual-input system is the sum of the two line currents, and must be limited to 60A maximum to protect the transfer relay in the Freedom SW 3000. Each breaker must not exceed 30A, and the total (sum) of the ratings of the two breakers must not exceed 60A.

AC Output Protection

The breaker between the Freedom SW 3000 AC output and the AC loads must be rated to protect the AC output wire size used. If the AC output wiring is based on the full 30A pass-through rating, then a 30A output breaker is acceptable. If the AC output wiring is smaller, then the breaker size will have to be smaller as well, in accordance with applicable electrical installation codes.

GFCI Requirements

A GFCI (ground fault circuit interrupter) is a device that deenergizes 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 requires GFCI protection of certain branch circuits. Consult all applicable codes.

Tested GFCIs

Compliance with UL standards requires that Xantrex test and recommend specific GFCIs for use on the output of the inverter. Table 1 lists models that have been tested and will function properly when connected to the AC output of the Freedom SW 3000.

Disconnect Devices

Each system requires a method of disconnecting the AC circuits. If the over-current 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.
