Single Phase 200A Electric Meter Burnt Out on 3-Phase 230V Supply, 30A Load

A single-phase GE KV2C class 200 electric meter rated for 200A was installed on a 3-phase 3-wire supply with a line-to-line voltage of 230V and a maximum load of 30A. Despite proper installation with tight terminals and a new 200A 5-jaw meter base, the meter and base repeatedly burnt out after several months of use. The supply voltage is 115V phase-to-ground, but the meter is connected across the 230V line-to-line voltage. The meter is self-contained without current transformers (CTs). Concerns were raised about the suitability of a small self-contained meter for this application, as such meters typically require CTs to reduce current input to 1 or 5 amps for accurate and safe operation. The issue may stem from improper meter selection or connection to a 3-phase supply using a single-phase meter rated for different voltage conditions, potentially causing meter damage due to voltage or current mismatches.
