Plugs & Receptacles

Plugs and receptacles are fundamental components of electrical systems, providing safe and reliable power connections for industrial, commercial, and heavy-duty applications. Designed to meet standard wiring requirements, these devices ensure secure electrical continuity while supporting repeated connection and disconnection of equipment. RSP Supply carries a full line of plugs and receptacles available in multiple configurations to support varying voltage, amperage, and environmental requirements.

Industrial plugs and receptacles are engineered to handle specific electrical loads and are designed to mate only with compatible devices, reducing the risk of improper connections. Many models feature rugged housings, moisture- and dust-resistant designs, and enhanced grounding to support safe operation in harsh environments. Switch-rated plugs and receptacles provide an added level of protection by incorporating an integral switching mechanism that de-energizes the contacts before the plug can be removed. This design allows operators to visually confirm that power is off, helping reduce arc-flash risk and unintended exposure to live parts.
