About NEMA Straight-Blade Plugs, Connectors, and Receptacles

About NEMA Plugs, Sockets, and Receptacles

Interference-Limiting Straight-Blade Receptacles and Plugs

Protect computers and other sensitive equipment from electromagnetic interference (EMI).

Receptacles have a ground terminal that is insulated from the mounting strap so you can run an isolated ground wire through the conduit. Also known as isolated ground receptacles. They fit standard wall plates (not included).

Plugs do not limit EMI on their own. Some are orange to match receptacles.

Note: The current rating of your plug should not exceed that of your receptacle.

Interference-Limiting Turn-Lock Receptacles

Protect computers and other sensitive equipment from electromagnetic interference (EMI). Also known as isolated ground receptacles, they have a ground terminal that is insulated from the mounting strap so you can run an isolated ground wire through the conduit. When mated with a plug, a quarter turn locks them in place to remain secure in high-vibration applications and prevent accidental disconnection. Receptacles fit standard wall plates (not included).
