our customer is using the building power supply for there equipment and the building owner is having us reuse a 480v single phase meter as metering device for billing purposes. The prints shows us reusing metering device but do you guys think that will fly with inspector? the 480v will be inline with circuit to meter power usage. We normally would use a Emon Dmon but thats not on SOW. my question is can a meter and meter can be used in such a way?
