Note that if the switch does not have over current protection, you will need an overcurrent protective device immediately adjacent to the disconnect

Is the disconnect before or after the meter? A meter disconnect is permitted by the NEC but not required. As stated the service disconnect rules are unchanged whether there is a meter disconnect or not.

It’s called “cold sequence metering” it is usually required by the poco on smaller 480 volt services.

OK, thanks to all the knowledgeable folks here I now understand the difference between 'cold sequence metering' and 'hot sequence metering'............but WHERE did the term 'sequence' come from ??

Don’t really know, that’s what the poco engineer told me. Those services are not CT, so the meter is plug or bolt in, so I assume it is to make it safer for the meter to be installed, unenergized, hence the “cold” part.
