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 marine electrical
supply store, RV supply store, or electrical products store.
Chassis Ground Wire Sizing
Connect a minimum No. 8 AWG
1
copper wire from the vehicle chassis to
the chassis ground terminal on the inverter DC panel.
Output Conductor Selection for Hardwire Installation
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
2
copper 2-
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.
