By code, probably, but by most utilities' requirements, no. Nearly all (maybe all) require a separate disconnect in addition to a backfed breaker.Can the load-side service connection in 705.12B, the breaker, be used for the disconnect required by 690.13? I'm in the 2017 Code
Definitely not all in all situations.... Nearly all (maybe all) require a separate disconnect in addition to a backfed breaker.
Per the NEC, yes.Can the load-side service connection in 705.12B, the breaker, be used for the disconnect required by 690.13? I'm in the 2017 Code
All the AHJs I deal with do, but I'll allow it.Definitely not all in all situations.
And the main utility I deal with, which has the most customers in the country, doesn't. That is, not for single phase and a plugin meter at 320A or less.All the AHJs I deal with do, but I'll allow it.
Typically they would just send a message to the disconnect inside the smart meter.... They can do that by bagging the meter and tossing it in the truck.
I had not heard of that. So there is a fully rated contactor in the smart meter? Must be pretty small.Typically they would just send a message to the disconnect inside the smart meter.
One of the utilities in our area will do that when fire dispatch calls and requests the utility to respond to a fire. Of course, that only works with self contained meters.I had not heard of that. So there is a fully rated contactor in the smart meter? Must be pretty small.
The 200A ones Tesla and Enphase use in their resi MIDs are only 3-4" in the longest dimension, they would fit. Not sure about 320A meters.I had not heard of that. So there is a fully rated contactor in the smart meter? Must be pretty small.
