EUSERC is an acronym for Electric Utility Service Equipment Requirements Committee. Formed in 1983, the purpose of the organization is to promote uniform electric service requirements among the member utilities, publish existing utility service requirements for electric service equipment and provide direction for development of future metering technology. There are approximately 80 utilities involved in EUSERC from 12 states. Not all EUSERC member utilities accept all metering devices that meet EUSERC specifications. So, although a device may meet EUSERC specifications, it may not be accepted for use by a specific utility company. Always check with the utility company for approval before using any metering device.
