Wiring Device-Kellems SpikeShield® IG5261 1-Phase Extra Heavy Duty Isolated Ground Single Standard Straight Blade Receptacle, 125 VAC, 15 A, 2 Pole, 3 Wires, Orange

Hubbell® patented the first isolated ground receptacle. Today - when a clean, noise free ground is more important than ever - Hubbell® is still setting the standard. Hubbell® uses insulation barrier construction on many models to isolate the ground contacts from the mounting strap. The green grounding screw is connected directly to the grounding contacts. In this way, ground contacts are separated from the mounting strap and also from the conventional grounding system. The isolated ground circuit is completed by running a dedicated insulated ground wire from the system ground buss to the green grounding screw.
