Chassis Ground Wire Sizing
Output Conductor Selection for Hardwire Installation

2. Once you have determined the total short-circuit current rating of
your batteries, select a fuse or circuit breaker that has:
•
a short-circuit interrupting capacity at least equal to the total
short-circuit current rating of your battery bank, and
•
a DC voltage rating of at least 16Vdc, and
•
a current rating no more than the values given above.
3. If a fuse is used rather than a circuit breaker, a disconnect switch
located between the battery and the fuse is recommended, to allow the
circuit to be de-energized when replacing the fuse.
Fuses and circuit breakers can be bought at any RV supply store or
electrical products store.
Connect a minimum No. 8 AWG
the chassis ground terminal on the inverter DC panel.
The inverter may be used by connecting cord-connected loads to the
receptacles on the front panel, and/or by connecting loads or a load circuit
to the AC output hardwire terminal block. If making connections to the
AC output hardwire terminal block, use jacketed No. 10 AWG
wire plus ground cable. Conductors may be solid or stranded.
Some installation codes require and we recommend use of oil-resistant
cable rated for damp or wet locations.
Color code for conductors:
Black = [L]ine (hot)
White = [N]eutral
Bare or green = [G]round
1.Based on US NEC 2008 article 551-20(c). Other codes may require larger
chassis ground cable, in some cases as large as the DC power cables.
2.Based on US NEC 2008, table 310-16, 75C copper wire.
