Therefore, the longer a cable is, the more important it is that the wire’s diameter be large.
Alternatively, a cable can have multiple pairs of wires to achieve a larger “effective wire diameter”.
This second approach gives a more flexible cable. For 10 ft long cables, SynQor recommends that
for the UPS-1500 Series:
• The AC INPUT cable have 3 wires (one for the ground) of 12 AWG
• The DC INPUT cable have 6 wires (three for each DC pole connection) of 12 AWG
• The AC OUTPUT cable have 3 wires (one for ground) of 12 AWG
• The DC1 OUTPUT cable have 4 wires (two for each DC Pole connection) of 12 AWG
• The DC2 OUTPUT cable have 6 wires (three for each DC Pole connection) of 12 AWG
Additional details about the effects of a resistance-related voltage drop are included in
