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.
2.6.1 WIRE SIZE
The tables below will assist in determining the appropriate wire size for
both the input and output connections Table 2-7 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.
