I thought the original intent was to have outside place for emergency services (like firefighters) to be able to disconnect electrical service from the dwelling?
Seems they are making this a lot more complex than it needs to be to meet that original intention. IMO a simple button on exterior to operate a shunt trip main should be an allowable option to meet this intent, but CMP's like to complicate things from the start with certain changes, then figure out all the potential misunderstandings, make a change or two the next cycle and then repeat again in the third cycle for many topics that have come up in more recent editions.
A serious, although hypothetical problem with that is the following scenario:
1. The POCO power is off (outage)
2. A need arises to safely disconnect the building.
3. Without power, the shunt trip has no effect.
4. POCO power is restored.
5. OUCH
And please do not try to tell me that if POCO is currently off, there is no need to disconnect.
