DC Cabling
Definition DC cabling includes all of the cables and connectors between the batteries, the DC
disconnect and over-current protection device, and the inverter/charger.
Type All installations require multi-strand insulated cables. The DC cables must be
copper and must be rated 105 °C minimum.
Size and Length See Table 3 for required DC cable length, cable size and required fuse size for the
RS3000. Wire size is usually marked on the cables.
DC Grounding
The inverter/charger DC (chassis) ground terminal needs to be connected to the
vehicle chassis by a minimum No. 8 AWG copper conductor that is either
insulated (green) wire rated 90 °C or bare copper.
Important:
Using a smaller gauge cable or a longer cable may cause the inverter to
shut down under heavy load.
