Hi All,

Trying to install HS220P3 dimmer switch. Found the neutral and ground but could not figure out the line and load wire. Ground wire (green) comes out of the old dimmer and is connected with the ground (copper) in the panel. Then 2 black wires come out and are connected to 2 different wires in the panel.

Used the non-contact voltage tester to detect but both the wires emit the sensitivity.

Need expert help to figure out the line vs load wire in this setup.

Thank you,

Sharad
