ELECTRICAL HOOKUP
For case-to-case wiring, run “greenfield”,
or other conduit, between junction boxes.
When connecting to the junction box on the
bottom left side of the case, field wiring should
exit the junction box from the right hand side,
furthest away from case wiring, increasing room
inside for wire connecting.
Electrical hookups are made to a
junction box located at the bottom left
hand front of the case. At the owners
option the case made be wired to a junction
box located on the top left rear of the case.
