Stop The Noise With Isolated Ground Plugs & Receptacles

The new Marinco® IG Series completes an isolated grounding system.
Receptacles separate ground contacts from their mounting straps, isolating the circuit from transient signals generated by "noise" producing sources.
The IG Series is perfect for very sensitive electrical and electronic equipment used in industrial environments.

Protect Sensitive Equipment
Conventional receptacles have grounding contacts that are connected to the box, fittings, conduit, and all other building ground system components, which can act as a large antenna for EMI and RFI.
The ground terminals on Marinco IG receptacles are designed to directly connect only to the service entrance grounding system, per NEC Article 250-146(d).

All 19 of the Marinco IG devices are orange, with an orange triangle indicating isolated ground.

Equipment requiring an isolated ground should use an isolated ground (orange housing) plug to show that the equipment should be connected to an isolated ground receptacle.

Ordering Options For Plugs

Bulk packing 50 per carton, with assembly screws backed-out: just add suffix ".OEM" to the part number.
