3B. ATTACH WIRING USING A
CONDUIT
1. Use the round hole at the bottom of the junction box to
attach conduit coming from the branch circuit. Attach
the conduit using proper conduit connector and bring
wires into the junction box. Leave 6” of wire free at the
end of the conduit to allow connections to be made.
2. If a fuse and fuse holder are to be used, the
knockout at the side of the box is for mounting
a Buss Fuse holder. Be sure the fuse and fuse
holder are of the same rating as the branch circuit.
Leadwires at the fuse can be either soldered in
place or attached using UL-listed 1/4” female
(receptacle) crimp connectors.
