I'm new to "cold sequence" on commercial projects but after doing research I somewhat understand it..

But from what I'm reading, it's mainly asked for on installs with voltages over 250v?

I'm even being told to add them on a simple line side wire change due to the wire falling apart?

Is anyone in nj seeing this new annoyance?
I spoke with pseg in Dover and after 3 phone calls I figured out it was a disconnect before the meter that was a different enclosure. I thought it was part of the meter but square d hadn't heard of anything and they claim the meter packs are rated for straight connection with no disconnect needs?

I'm also learning they're asking for lever bypass on the new meters but haven't heard of that before either.

Just wanted your guys thoughts

Cold sequence is like hot sequence, just the main service disconnect is before the metering. Metering might be a feed through or with CTs.

In many cases the meter disconnect switch is not the service disconnect. A meter disconnect switch is not normally used with CT meters.
