Each main panel should include ocp so that is how each building is shut down.

The feeders from the meter enclosure must be disconnected in the meter enclosure. Not a problem for a sparky.

What's the worry?

Not sure about Canada, but I believe current code in the USA would require an external disconnect at each building.

It's a ct socket. Much better than the direct meter 320 that some utilities like. No you cannot pull the meter to disconnect power. Often we would have a switch next to or built into the same box as the meter, yours doesn't.

You have a main disconnect at each building. That is all that the electrical code requires. It's no different than if you had the meter hanging on the side of the building.

In an emergency the wires can be cut at the pole to disconnect power.

As stated above, this is a CT meter socket. Think like your clamp on voltmeter to check amps. You are not physically breaking the wire when the meter is pulled. You will have to install a disconnect switch if you feel the need at the metering point. As stated before, there should likely be a disconnect at the buildings.
Power provider will have to disconnect the power to the meter socket. If you try to disconnect this yourself there will be two emergencies.

For now, the exterior disconnect is only required for the dwelling unit. I'm sure that will change in the not so distant future. There is a lot of money to be made with 3R disconnects.

Yeah, per NEC code.

Around here the AHJ is supposedly requiring it in all buildings. Thankfully I didn't need an inspection so it didn't come up.

I edited it for a little clarity. The emergency disconnect doesn't actually have to be attached to the dwelling, but does have to be within sight of it and marked "emergency disconnect". A lot of rural areas have a meter main on a pole and that is usually fine. I did my new service in 2020 but six months before the 2020 code went into effect; my meter main is on a pole, but not within sight of the house unless you are on the roof due to my wife's garden. It wouldn't pass now, but IDGAF.

We have a central meter panel w/o any disconnects, and 200 amps to the house and 100 amps to the nearby well and 100 amps up the hill to our shop. When (someday) I have them put in a transfer switch just past the meter, that will serve as an emergency disconnect. In the mean time, when I wire the shop, the electrician will have to pull the meter; right now we have a temp work panel. This was installed in 2000, long before the house was finished.

Yep, rather then set a pole I built a nice shed and put a 10' mast down to a meter/main. PoCo had some back and forth on what they "recommended per the AHJ" and the meter/main ended up being easier anyway, even with that it was suggested I have on at the house even though this is 50' away and visible. Since I'm single family residential and outside of the city, no permit and no inspection, no disconnect. Garage will be 75' in the other direction and won't have one either

Damn. I looked it up and was wrong...again. It doesn't have to be within sight. 230.85 says it has to be in a readily accessible outdoor location, which of course would leave it up to the inspectors interpretation of readily accessible which is actually defined in the NEC and no mention of being visible is made.

Before you buy and install this set up lets talk about what will need to happen when someone decides a whole house gen set with auto transfer is required or solar needs to be added?

I wish I had a simple answer. I had a 320A service installed without asking this question.

[wyliesdiesels]

as said above, that is a CT meter not a feed thru meter.

if you want to be able to disconnect individual buildings, youll need a disconnect for each

but since this wont be your meter main, how about showing us what your main service panel will have. Individual breakers for each building?

and yeah dont pull the meter before shorting the terminals. nasty things will happen with CTs with a load running thru the core.

 

[wyliesdiesels]

OP here.

This being a rural property, I have thought about a whole house backup generator. So now how does that change things?

if you want an ATS, would the generator supply backup power to the entire property or just the house?
