3.8. Load Connections

Cable Size Considerations

The dc load cable(s) should be sized to limit the voltage drop from the dc power plant to the loads per system design requirements. The cable(s) must also carry the full load current during battery operation. During battery operation the voltage will be lower and for constant power loads, the current will typically be higher. If assistance is required to determine the necessary cables for the application, contact your sales representative or APC.

Circuit Breaker Protected Load Connections (30 or 60 A)

The circuit breaker lug landing connection provides a pair of #10-32 studs on 5/8” centers for mounting two-hole lugs. A ring size of 6 mm may also be used. A right angle bus bar with two studs is provided to land the lugs. Load Connections should be made as shown in. Cover connections with heat shrink after assembly.

GMT Fuse protected Load Connections

Connections for ¼ to 14-A loads require a ring terminal with a 0.170 in (4.3 mm) clearance hole and are located at the rear of the unit. Load connections should be made as shown in Figure 3.8-2 and Figure 3.8-3
