Look Inside a GP3 and 4
GP3 and GP4
GP3 and GP4 panels are very similar. GP3 panels have three
dimming circuits, with input circuit breakers provided, while a GP4
panel has four dimming circuits and no circuit breakers. One
difference is the way of wiring Neutrals in the GP3 and GP4 panels. A
GP3 panel has three terminals for all Neutrals bussed together. A GP4
panel has two Neutral terminal blocks provided for each circuit (one
for input and one for load).
Notes:
■
GP3 can be wired as 3Ø, 4 wire or 1Ø, 2 wire. If wiring is 1Ø, 2
wire, 3 #12 AWG (2.5mm
2
) must be spliced to the Hot/Live feed
wire.
