Electrical Hookup

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.

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.
