We discussed this recently but I'm unsure if anyone ever got an official answer. You might need to email the DCA.

Emergency Disconnects for One- and Two-Family Dwellings

As with any adoption of a new code, new requirements come along with it. The 2020 edition of the National Electrical Code (NEC/2020), aka NFPA 70, was adopted on September 6, 2022, at N.J.A.C. 5:23-3.16. With it came Article 230.85, Emergency Disconnects, and applies to new services on one- and two-family dwellings only. For those of you familiar with the building codes, please do not apply these definitions. Remember, the NEC/2020 has specific definitions in Article 100 and this is where you would find how Article 230.85 applies to these types of buildings: A “Dwelling, One-Family” means, “A building that consists solely of one dwelling unit.” While a “Dwelling, Two-Family” means, “A building that consists solely of two dwelling units”. The word “solely” above means that Article 230.85 applies to one- and two-family detached dwellings and would not apply to townhouses/rowhomes or multi-family buildings. When it comes to a Rehabilitation project, you will note that materials and methods at N.J.A.C. 5:23-6.8(d) does not delete this section; thus, it would be included per the scope of a project, as outlined at N.J.A.C. 5:23-6.2(b). This requirement would be limited to complete service changes and upgrades to these types of homes. “Complete” implies that the project includes new service conductors, service entrance conductors and service equipment. One of the early questions we have received, pertains to whether a separate ground and neutral would be required when installing these disconnects, similar to the installations of subpanels. Officials should take note that the NEC offers three options for compliance. The only method that requires the disconnect to be marked as “Service Equipment” would be the only one that would require the installation of separate grounds and neutrals.
 
This is what we received directly from the DCA.

Subject: Rehab CCC for Spr 2023
Rehab Grace Period and the 2021/2020 Codes
I don’t know about you, but anytime I see/hear the word Grace, I immediately think of National
Lampoons Christmas Vacation. For a reminder, here’s how it went:
Aunt Bethany: “Grace? Ohhh… She passed away thirty years ago…”
Uncle Lewis: “They want you to say Grace… The BLESSING!”
Aunt Bethany says, “Oh.”
Anyway, this article has nothing to do with a movie or blessing and serves as an explanation of the
applicability of another Grace, as in Period, found at N.J.A.C. 5:23-1.6) and its relationship to the
changes in the rehabilitation subcode. This question is common when changes to the rehab subcode
are made following the adoption of more recent editions of the model codes. To the extent that
changes to the rehab subcode involve section number changes, with the requirements remaining
the same, there is no real issue. However, if a new requirement is being added to the rehab
subcode, then the grace period would apply. The decision to add – or not to add – a requirement to
the rehab subcode is one that is taken deliberately. It is not automatic upon adoption of the most
recent edition of the national model code.
That all being said, I am happy to say, we made our informal deadline of having the rehab updates
adopted by the end of the new code cycle’s 6-month grace period. We have received notice from
the Office of Administrative Law that the September 6, 2022 proposal has been adopted March 6,
2023. Therefore, for those who wish to use the previous provisions, a complete permit application
would have to be submitted on or before September 5, 2023.

My first time doing a residential 200A service upgrade under the 2020 NEC. I'm seeking confirmation on the outdoor service disconnect wiring to the interior breaker panel. So would the wiring from the 200A OH meter to the WP disconnect be 3 wire, (in a PVC nipple) then the disconnect would be neutral bonded to ground, and then a 4 wire SER ran from the WP disconnect to the main lug panel inside the house with the neutral isolated. No main breaker in the house panel if the WP disconnect contains a main breaker? The WP disconnect is then labeled Service Disconnect? Any other options as far as WP disconnects? Many thanks in advance.
 
I get different answer from different inspectors. its ridiculous. no one seems to know what is going on. I've had many inspectors say if its rehab you don't need disconnects outside. I don't feel like making 8 million phone calls to find the answer, then have to battle every township.

Here in Massachusetts we have been through all this as we adopted the 2020 NEC January 2020 and 230.85 is still interpreted differently everywhere.

The 2023 NEC clears up alot of the confusion. For example if the equipment is ONLY suitable for service equipment... you ONLY can run 4-wire to the next distribution panel and you need to separate N & G.

Then only need the Emergency Disconnect if doing a complete service change...see exception to 230.85(C). This is important for the storm damage repairs to risers torn down in storms.

In Mass we added a remote option that was important for City utility distribution neworks all underground into the dwellings. This also will work well with mansions with larger services. Who wants an 800-amp disco on the side of their home?

Here we would never apply 230.85(2) as no utility will allow cold sequence for residential services.

I feel your pain. Best to call the AHJ ahead of installation.
