In February 1968, 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.

• La construcción de la barrera de aislamiento aísla el contacto de tierra de la correa de montaje
• El hueco de retención del cableado para el cableado trasero y lateral reduce en gran medida la posibilidad de aflojar la conexión del terminal
• Cara de nailon de alto impacto y resistente al abuso
• El sistema de montaje y conexión a tierra totalmente de latón proporciona una ruta de tierra de menor resistencia y mayor resistencia a la corrosión que los sistemas de montaje de acero.
