What are isolated Ground units?

Solid state electronic equipment contain microprocessors that are adversely affected by Electromagnetic Interference (EMI). In Geist’s Isolated Ground units, the receptacle ground conductor is permitted to pass through panel boards, junction boxes, etc. without being bonded to the equipment grounding conductor. This isolation minimizes EMI potential within the installation. An external chassis grounding wire is electrically isolated from the receptacle grounding wire. It must be connected to a reliable earth connection to minimize the potential for electrical shock. Isolated Ground PDU’s are especially beneficial in audio/video applications. More information on NEC’s codes for isolated ground systems can be found in the NEC Section 250-146(d). Standard Geist Isolated Ground units can be found on pages 11 and 24.
