Figure 12, E-Panel Wiring Connections
AC Wiring Connections
The AC Bus-Bars (for neutral and hot connections) have dual sizes. The smaller nine holes accept
#6 to 14 AWG wire and the larger two holes accept #1/0 to 14 AWG. Torque small screws to 30
in-lbs (3.4 NM) and the large screws to 45 in-lbs (5.1 NM).
DC Wiring Connections
The DC bus-bars (for battery positive/negative and PV) have dual sizes. The smaller nine holes
accept #6 to 14 AWG wire and the larger two holes accept #1/0 to 14 AWG. Torque small screws
to 30 in-lbs (3.4 NM) and large screws to 45 in-lbs (5.1 NM).
The DC shunt uses 3/8” bolts and requires cables having ring terminal lugs with a 3/8” hole.
Torque these bolts between 10 to 12 foot-pounds.
The 175A and 250A DC Disconnect (Main Battery Shut-Off) uses a 3/8-16 stud and requires
cables having ring terminals with a 3/8” hole. The 125A DC Disconnect has 1/4-20 studs and
requires cables with a 1/4” hole. Torque the 175 A and 250 A breakers to 220 in-lbs (24.9 NM)
and torque 125 amp breakers to 30 in-lbs (3.4 NM).
Ground Connections
The ground bar has nine holes and accepts #6 to 14 AWG wires. Torque small ground screws to
20 in-lbs (2.3 NM) and the large ground screws to 45 in-lbs (5.1 NM).
