3.4 Wire Sizing and Lug Size
The DC output is available from a set of copper bus bars, one for the positive terminal, out for the
negative terminal. Each bus bar has two screw studs, (Penn Engineering, HFHB-0518-24, see
www.pennfast.com
) to which a set of two nuts and lock washers are attached. The
recommended ring-lug size that mates with these 5/16-18 thread studs for connecting output
wiring is 5/16” (standard) or 8M (metric). The wire gauge and ring-lug crimp size must be
matched. Crimp ring lugs are generally available from Tyco/AMP and catalog vendors like
Mouser, Digikey etc. See paragraph 3.5 for AC input wire lug size.
Figure 3-2: DC Output bus bar studs.
Care must be taken to properly size all conductors for the input and output of the power supply.
Table 3-7 bellow 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.
