UNBALANCED BRANCH CIRCUIT MONITORING
Unbalanced branch circuits are commonly used for large loads with multiple voltage requirements,
split receptacles, and sub-panel feeders throughout the building. These circuits can be identified by a
double-pole breaker in the electrical panel. Cabling typically consists of black (line 1), red (line 2), and
white (neutral) conductors with a bare copper (or green) ground conductor.
A typical split-phase residential service entrance is an example of a 240V unbalanced circuit.
Two (2) sensors are required for monitoring unbalanced circuits. The sensors should be installed on
both line conductors of the circuit (typically black and red).
