WIRE SELECTION
Care must be taken to properly size all conductors for the input and
output of the power supply. This section provides guidance in the
selection of wire size. Note that cables with Class B or C stranding should
be used. Fine stranded cables should not be used unless crimp-on lugs
or ferrules are used that are approved for fine stranded cables.
2.5.1 WIRE SIZE
The tables below will assist in determining the appropriate wire size for
both the input and output connections Table 2–4 below gives
minimum
recommended wire size. This table is derived from the National Electrical
Code; it is for reference only. Local laws and conditions may have
different requirements. Note that these recommendations are for copper
wire only. For higher ratings, wires can be paralleled; refer to the National
Electrical Code.
