Isolated Ground Devices

Isolating the grounding circuit from electrical noise is an efficient and economical way to protect sensitive electronics in AV systems from operational degradation, disruption, or damage.

Isolating the grounding circuit from electrical noise is an efficient and economical way to protect sensitive electronics in AV systems from operational degradation, disruption, or damage.

CONVENTIONAL RECEPTACLE

A conventional receptacle is grounded to the building grounding system at the receptacle. When mounted in the box, grounding contacts 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.

ISOLATED GROUND RECEPTACLE

Grounding contacts are bonded directly to the service entrance grounding system. In the illustration the insulating barrier (A) isolates the grounding contacts (B) from the mounting strap (C). The insulated grounding conductor (D) is bonded to the service entrance grounding system.
