We have 1 POCO that allows metering at the transformer here. They just install the CT donuts inside and mount the meter on the side of the transformer.
Another would put the CT donuts inside the transformer, but you have to mount the meter remote on pedestal or building.
On 480volt services, Cold Sequence is required for metering and on the smaller services, 320 meter or less the cold sequence disco doesn't require fuses...and isn't considered the Service Disconnect.
