Phase Inspection. 1  Inspect the electrical system as a whole including outlets, GFCI & AFCI protection, switches, fixtures, panels, circuit breakers & disconnects. 2  Inspect the plumbing for any visible leaks, drips, water supply, proper venting of the drains and waste lines.
Phase monitor relays provide protection against premature equipment failure caused by voltage faults on 3-Phase sys-tems. All Prosense phase monitor relays are designed to be compatible with typical Wye or Delta systems. Phase monitor relays protect against single phasing regardless of any regen-erative voltages.n Wye systems, a connection to a neutral is not re-quired.The relay is energized and the LEDon when the sequence is correct. Any fault will de-energize the relay and turn off the LED. Re-energization is automatic upon correction of the fault condition.
