ōCoils have a shield wire which must be connected to the meter. This reduces interference and
improves accuracy of the CT.
Connecting Voltage
1) Connect the voltage leads (L1, L2, L3, and N, as necessary) to the meter. A voltage lead of 14 AWG
T
HHN Minimum 600VAC rating (or equivalent in order to maintain 600VAC safety rating of the
device) is required.
2) Connect the leads to the circuit breaker.
a) Refer to the wiring diagrams in for wiring
connection specifics. Follow local electrical codes
during this installation.
b) IMPORTANT: Verify the breaker is marked as th
