230.85 on 400 amp services

[augie47]

We have had our 1st AHJ adopt 230.85 (this area has been on the '2017 NEC previously)
On 400 amp services (dual 200 amp panels) what is the most common method of addressing this requirement in your area ??

 

[Greentagger]

No difference. 2 -200A exterior mains, grouped, and each labeled EMERGENCY DISCONNECT. Did I misunderstand the question?

The 2017 did not require the EM disco.

Welcome to the nightmare!
Below is an example of an installation in 2020 when no equipment was available with sectioned disconnects per 230.70

I gotta ask why you asked. The only tell I see is the strut strap.

No I am right handed

They are a Zinsco design by Milbank, they came to Milbank when they bought Unicorn, have a Sylvania 200A 3 pole breaker & a Milbank 200A 3 pole model side by side & the handle ties are exactly the same, like they were from the same mold.

Nothing wrong with those Zinsco main breakers AFAIK.

I get NUMEROUS calls about insurance calling all Zinsco bad and people needing their mains replaced. I would just make sure the customer knows enough to call out their insurance.

Yeah, well, do those say 'Zinsco' on them?

Same here, and I have never came across any real peer reviewed published research that all Zinsco are bad, just hype up by 'home inspectors'.
I have herd some anecdotal experiences where they don't trip but thats all.

Does your Poco allow an expansion fitting at meter instead of a slip fitting?

 

[shortcircuit2]

Yes a fitting to allow for settlement
