An electrical panel meter system may include a plurality of meter modules housed in an electrical panel enclosure. Each meter module may be configured to sample electrical readings related to electrical power provided to a respective branch circuit of the electrical panel meter system. To field test the metering accuracy of each meter module, a field tester may be coupled to the electrical panel enclosure. The field tester may inject an electrical signal via a test conductor provided in the electrical panel enclosure. The test conductor may be coupled to each meter module. The field tester may measure an electrical parameter of the injected electrical signal and compare it to electrical readings sampled by the meter modules. A pass/fail result for each meter module may be indicated. Methods of field testing meter modules in an electrical panel meter system are also provided, as are other aspects.

Apparatus and methods for field testing an electrical panel meter system

A circuit breaker and method includes a mechanical pole moveable between a latched position and an unlatched position to open an electrical connection between a pair of electrical contacts. An electronic tripping device is configured to respond to a sensor signal. The sensor signal is output from a condition sensor wherein upon receiving the sensor signal the electronic tripping device trips the mechanical pole into the unlatched position.
