The following considerations should be made to select wiring for connecting the load to the power supply:

Current carrying capacity of the wire (refer to Section 3.9.2)

∗

Insulation rating of the wire should be at least equivalent to the maximum output voltage of

∗

the power supply.

Maximum wire length and voltage drop (refer to Section 3.9.2)

∗

Noise and impedance effects of the load wiring (refer to Section 3.9.4).

∗

3.9.2 Current Carrying Capacity

Two factors must be considered when selecting the wire size:

1. Wires should be at least heavy enough not to overheat while carrying the power supply

load current at the rated load, or the current that would flow in the event the load wires were shorted, whichever is greater.

2. Wire size should be selected to enable voltage drop per lead to be less than 1.0V at the

rated current. Although units will compensate for up to 5V in each load wire, it is recom-
