What is the difference between hot and cold sequence metering and are the EZM metering and the Meter-Pak devices considered hot sequence or cold sequence type metering?
Issue:
Product Design
Product Line:
EZM, MP Metering
Resolution:
In hot sequence metering, the tenant circuit breaker is located downstream (load side) from the meter. Turning off the tenant circuit breaker does not deenergize the meter. In cold sequence metering, the tenant circuit breaker is located upstream (line side) of the meter. Turning off the tenant circuit breaker does deenergize the meter. Both the EZM and MP Metering devices are considered hot sequence metering.
