OK. So, here's the UNOFFICIAL version that I received from an inspector in my contractors' association, who is in constant contact with the DCA. NJ is PLANNING on releasing the 2020 Rehab Code on or about March 6, 2023. At that point in time you will begin a 6-month grace period under which you can continue to replace 1 and 2 family electrical services without having to install an outdoor disconnect. You would have to indicate that you are filing under the 2017 Rehab Code on the permit app. This will apply to complete service upgrades (SE cable, meter pan, ground rods and main breaker panel). If you are changing out a panel only you will not be required to install an outdoor main disconnect. This rule will not apply to multi-family housing or condos.
That said, I'm guessing there will have to be some exceptions to this rule. For example, when you have houses that are dense-packed together (i'e. Hoboken and Jersey City) installing outdoor disconnects is usually not possible.
Remember, this is unofficial. EI's may not follow this directive unless it's carved in granite !!! Bulletins and Code Communicator articles, while they may provide important information, are not enforcalbe.
