Single Phase Equipment Ground Fault Circuit Interrupters (Gfci)-Connecting To - Vanguard CPW 125-4-S Series Operation And Maintenance Manual

another path for the GFCI to trip. GFCIs do not protect against line to line or line to neutral contact hazards such as result
from bare connectors or terminals, etc. Note: GFCI should be tested daily, refer to the Ground Fault Circuit Interrupters
(GFCI)—Test Daily section of this manual.
Move each of the 50Hz single phase equipment circuit breakers to the ON position to energize its corresponding receptacle.
Move each of the 50Hz single phase equipment circuit breakers to the Off position to de-energize its corresponding
receptacle, if required. The output for each receptacle is:
RC 13 — 240V/15A/50Hz supply. CB 17 — Energizes receptacle RC 13.
RC 14 — 240V/15A/50Hz supply. CB 18 — Energizes receptacle RC 14.
RC 15 — 240V/15A/50Hz supply. CB 19 — Energizes receptacle RC 15.
RC 16 — 240V/15A/50Hz supply. CB 20 — Energizes receptacle RC 16.
RC 17 — 240V/15A/50Hz supply. CB 21 — Energizes receptacle RC 17.
CB22 — 240V/63A/50Hz supply with GFCI. CB 22 — Energises power buss circuit for CB 17, CB 18, and CB 19.
Provides GFCI protection for receptacles RC 13, RC 14, RC 15.
CB23 — 240V/40A/50Hz supply with GFCI. CB 23 — Energises power buss circuit for CB 20, CB 21. Provides GFCI
protection for receptacles RC 16, RC 17.
Note: Both CB 22 and CB 23 together with the sub-circuit breakers (CB 17 through CB 21) must be energized in order to
obtain voltage through receptacles RC13 through RC 17.
Single Phase Equipment Ground Fault Circuit Interrupters (GFCI)—Connecting To
All electrical sub-circuits connected to the single phase front-mounted equipment receptacles should be made by a qualified
electrician. Failure to make correctly wired connections to the GFCI could result in the inability to set the GFCI due to a
perceived ground fault by the GFCI.
The single phase equipment circuit breakers CB 3 through CB 9 for 60Hz operation, or CB 22 and CB 23 are equipped with
ground fault circuit interrupters (GFCI). Electrical connections to any of the front-mounted receptacles must not cause
current to flow back through an alternate ground path:
For 60 Hz operation:
•
Equipment or circuits connected to receptacles RC 1 through RC 5for 60Hz operation must have the neutral
connected through the corresponding receptacles' neutral.
•
Equipment or circuits connected to receptacles RC 6 and RC7for 60Hz operation must have the neutrals connected
through the corresponding receptacles' neutral AND they must be grounded through the receptacle, DO NOT use a
separate grounding path.
For 60 Hz operation:
•
Equipment or circuits connected to receptacles RC 13 through RC 17 for 50Hz operation must have the neutral
connected through the corresponding receptacles' neutral.
