Agreed. Homeowner wouldn't pony up and we have several new 200a disconnects in stock (we are a commercial/residential generator installer, but do not normally wire branch circuits or service drops. This allows us to work with several ECs without conflict). I'll reconsider a meter main. It is the more elegant solution. Just trying to minimize excessive cash outlay. The inspector recognized the installation was not unsafe, just not code perfect (~30" of unbroken/unfused feeder in a pull box in a garage) and gave us a couple of weeks to correct. In this jurisdiction, no plan review is required for this type of permit. Good question, because they didn't separate the neutrals in the panel (arrgh!). It looks like an afterthought as they ran a separate conduit from the can through the attic to the panel (maybe AHJ leaned on them inappropriately).

200a SE Rated w/Load Shedding (20kw Genset). Just soliciting opinions to get it right before the final.

Jim, thanks for your answer. The AHJ is requiring the installation of a Main Disconnect near the Meter. We added a Service Entrance Rated ATS near the Main Distribution Panel that also has a main disconnect (in the garage 35 feet from the existing meter). So we essentially had a change of service from the existing MDP to the new ATS (less than 2 feet apart). We had a custom fabricated pull box to make the transition from the existing rigid conduit inside an interior garage wall to the new surface mounted ATS. The pull box introduced unfused conductors in the building (inside garage), thereby requiring the new disconnect. I have already separated the equipment grounds and neutrals in the existing distribution panel and will remove the bonding screw when the new disconnect is installed and existing Main becomes a sub-panel. There are four wires coming from the existing meter can (2 primaries, 1 neutral and a ground) to the existing MDP. I was looking for input from an inspector's perspective on what I had hoped would be a simple way of installing the new disconnect. I had planned to: 1. Set the new disconnect next to the existing meter can joined by two 2 inch nipples. 2. Disconnect the load lines in the existing meter can and land new conductors through one of the 2 inch pipes to the line side of the new disconnect. 3. Attach new conductors on the load side of the new disconnect and feed them through the remaining 2 inch pipe and polaris tap them to the existing load lines that were disconnected from the load side of the meter in step 2. 4. Based upon Jim's answer, it's obvious I also need to bring the Neutral into and out of the new disconnect box as well as bonding it to the new box and appropriate grounding to the GEC. If the above seems reasonable, since a ground wire already runs unbroken from the meter can to the equipment ground bus on what will become a sub-panel, would a wire from a ground lug in the new disconnect run to a ground lug in the existing meter can be sufficient for the system? I will now go quietly into the night.

I need to add a 200a Main Disconnect at the MC. The existing load lines proceed unfused to the MDP. 1. At the MC, can I disconnect the existing load side hots and and land new conductors in the new Main Disconnect on the line side without bringing over a neutral to the MD? 2. Can I then bring the load side of the new disconnect back into the MC (separate conduit) and polaris tap the existing load conductors? 3. There is a separate ground wire from the MC to the existing MDP. Is it sufficient to connect a ground wire from the MC to the new MD (still unbroken segments)?
