Wire Size Selection

FIRE HAZARD Select a wire size large enough to carry short-circuit current without overheating. Two factors must be considered when selecting wire size for load connections: conductor temperature and voltage drop. To satisfy safety requirements, load wires must be heavy enough not to overheat while carrying the short-circuit output current of the unit. Table 4-1 lists the current-carrying capacity (ampacity) for various sizes of stranded wire.

Note that the minimum wire size required to prevent overheating may not be large enough to prevent OV trip and to maintain good regulation. Under most conditions, the load wires should be heavy enough to limit the voltage drop to no more than l.0 V total (see Figure 4-6). With remote sensing, load regulation is degraded ImV per 200 mV in the -V output load lead (see page 50). On the 40 W low voltage outputs, when the output voltage is set to 7 V, there is no voltage drop
