I. TO DISASSEMBLE RECEPTACLE INTERIOR

1. Remove polarizing screw and washer.
2. Rotate terminal holder counter-clockwise.

II. TO CONNECT CONDUCTORS TO RECEPTACLE INTERIOR

1. Strip insulation from ends of individual conductors.
2. Loosen screws in pressure connectors and slide prepared ends of conductors into
the connectors, observing proper polarity. Tighten screws.

III. TO REASSEMBLE RECEPTACLE INTERIOR

1.Insert Terminal Holder and turn clockwise until front end is approximately 1/4" inside
of casting surface. Recessed radial depression in Terminal Holder must be lined up
with polarizing washer/locator. Replace screw through the ground strip.

IV. POLARITY AND PHASE ROTATION

1. ACP, CPH Plugs and EBR Receptacle are polarized so that the plug will enter the
receptacle only one way.
2. Special Polarization: suffix - P4 added to catalog number of the receptacle. Prevents
plug insertion in a receptacle wired for a different voltage (doesn't apply for 150 Amp).
