Multi-circuit monitors are available in a range of enclosures, and the wiring approach required can vary depending on the enclosure, the current transformer, and the equipment to be monitored. Multi-circuit monitoring systems are intended to be installed by qualified personnel only.
Packet Power’s multi-circuit wireless devices support 1 to 72 CTs and offer a mix of full power and current only monitoring. Monitors are built to customer specifications and ship fully configured for:
Voltage source, type, quantity, lead color and lead length
CT type, rating, quantity
CT lead type -- loose leads or flexible wire harnesses for some models
Wire exit location
Overcurrent protection
Measurement type - full power or current-only
See Branch Circuit Monitoring (32 - 198 CTs) for information about Packet Power’s branch circuit monitoring solutions for panelboards, RPPs and PDUs. Packet Power offers a wide range of split-core and solid-core Current Transformers (CTs) as well as flexible Rogowski coil sensors. View our list of Current Transformers.
Multi-Circuit Monitor Configurations
Packet Power supports multiple generations of multi-circuit monitors. If in doubt about your monitor, simply look at the power meter display. The BGSXX models also ship with CT ribbon cables and CT interconnect boards.
