2.4 WIRE SIZING
Care must be taken to properly size all conductors for the input and output of the power
supply. Table 2-5 below gives
minimum recommended wire size for the input. This
table is derived from the National Electrical Code and is for reference only. Local laws
and conditions may have different requirements. The table is for copper wire only.
