spare bonding lug on the control. Follow all local electrical codes.
Reconnect the Blower Motor Power Cord
If required, reconnect the blower motor power cord at the control.
Route the blower motor power cord through a strain relief on the second junction box. Tighten the
strain relief.
At the end of the cut power cord, strip back the cable jacket about 3″ (76 mm).
Using a wire nut, cap off the unused brown conductor in the cable jacket.
Strip about 3/8″ (10 mm) of wire insulation from the remaining control wires.
