The WESCO 3864 is a 30-amp flush mount receptacle wired in a 3-wire configuration, designed for use in residential and light commercial electrical installations. This outlet-style device mounts flush to a standard electrical box and is built to handle 30-amp branch circuit loads. Licensed electricians install this type of receptacle in applications such as dryer circuits, air conditioning units, and other dedicated 30-amp loads. The flush mount design keeps the face of the receptacle flush with the wall plate for a clean, code-compliant finish.
The 3864 is suited for 30-amp dedicated branch circuits in both residential and light commercial settings. Typical applications include laundry rooms, utility spaces, and equipment rooms where a dedicated 30-amp outlet is required by code. Its 3-wire design accommodates hot, neutral, and ground conductors in standard 30-amp circuit configurations.
Designed as an OEM-style replacement or direct installation receptacle for standard 30-amp flush mount electrical box applications in residential and light commercial wiring systems.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the branch circuit at the panel and verify with a voltage tester before beginning any wiring work. Ensure the electrical box is properly rated for the load and that conductors are correctly sized for a 30-amp circuit. Do not exceed the receptacle rated ampacity.
