I am replacing a 3 Way switch (master) and remote dimmer with Decora Smart devices. The master has the correct wires to install the smart 3-way dimmer master. The remote box had a dimmer device with a line?, travel, ground and another wire (load?) that did not connect to any of the wires in the master box. The remote box does not have a neutral wire. Instead, the ground wire is tied to the neutral wires in both boxes.
My 2 questions: 1) How do I find and detach the neutral to ground connection if needed? 2) Can I use the other black wire (former load?) as a neutral wire. The Leviton Decora Remote (DD00R-DLZ) does not required a load connection because the traveler signals the master box to turn on/off the circuit?
