Replacing 3 dimmers and one single pole switch in a 4 gang setup with Legrand dimmers and a Single Pole switch.
Original wiring by licensed electrician.
Existing dimmers have R,B,R/W(Not connected)and ground wires.
The Legrand products are frame grounded, eliminating the ground wire for each dimmer. The Legrand dimmers have wires labeled Common (B), Neutral (W), 3-Way (R) and I-Pole (R).
I understand the wiring except for the I-Pole wire. The existing setup does not provide an extra wire going to each dimmer. What do I do, if anything, with the I-Pole wire?
