Neurio W2 - Alternate Wiring with Wire Tap

Alternate wiring with wiretap
If an empty breaker isn’t available, you can use the provided wiretaps to
connect to an existing breaker. To do this, remove the existing wire from a
15 or 20 amp breaker and replace it with the jumper wire provided in the
contents of the box. Then use the wiretap to connect the jumper wire, the
wire from Neurio, and the original wire you removed from the breaker. It
might take a little force to ensure the wires are secured into the wiretap all
the way.
Note: The blue wire is not used for 2 phase installs. Twist the
marrette onto the blue wire and tuck it into the panel, out of the
way
