Q:
Which wire is the “hot” wire versus the “load” wire?
A:
To determine this safely, begin by confirming that power is off to the device
location at the circuit breaker. Cap all of the exposed wires in the electrical
box, then turn the power back on to the device location. Find your non-
contact voltage tester. Place your voltage tester next to each of the wires.
The voltage tester should indicate which of the two wires is receiving power
from the circuit box (refer to the voltage tester’s user manual for details on
operation). The “hot” wire is the powered wire.
To safely complete your wiring, turn off power at the circuit breaker until the
device is secured into the wall.
