Characteristics of Isolated Ground Wiring Devices
Isolated ground devices help limit electrical noise on the equipment grounding circuit by providing two grounding paths for the installation. The device grounding circuit terminal and grounding contacts are isolated from the grounding path of the metal outlet box, device mounting means, and metal cover or wall plate, thus establishing a separate, dedicated equipment grounding path for connecting noise-sensitive equipment.
250.119 (B) says "where the condiions of maintenance and supervision ensure that only qualified persons service the installation. "
That statement doesn't apply to most church maintenance men
