Wire type
Due to the small size of this box and limited wire bending room, it is required that the super flexible type battery
cable be utilized. Cobra Cable X-Flex is one approved type of cable. Welding cable although not listed for use in
residential wiring will also meet the flexibility requirement. Wiring for the din rail mount breakers such as 6AWG
for PV circuits may be the stiff THHN or similar type of wire.
Top view showing three 1” knockouts. The left two
knockouts fit charge controllers such as the Classic,
MX60, C-40 and Tristar controllers
The left side of the
MNDC chassis has
three 2” knockouts
and two ½”
knockouts. The 2”
knockouts are
intended for inverter
DC cables. If installing
to a Trace or Xantrex
SW inverter, use a 2”
offset nipple to attach
to the SWCB conduit
box.
If routing cables
directly through the
hole with no conduit,
make sure a plastic
grommet is installed
to avoid chafing.
The bottom surface is normally where the battery
cables will enter. The 1” knockout can be increased in
size to accommodate a second 2” conduit opening if
required. This is one way to hook up to a Trace or
Xantrex DR Series conduit box.
