Disconnecting means

[GerryB]

Art 690.13(C) in the 2017 code reads the supply side disconnect needs to be "listed as suitable for use as service equipment." I do not see that in the 2020 code. Also 230.82(6) in the 2020 says ..."if" provided with a disconnecting means listed as suitable for use as service equipment...
So my question is does a supply side disco no longer need to be service rated. Thanks

My first inclination is to simply say: Forget what the code says, don't be stupid, and just put in a service rated disconnect. You don't want the thing to blow up in a fault because it's not service rated. Of course any equipment that's connected directly to the service should be service rated. Physics does not give a --- what the code says and the product standard for service rated equipment is what we rely on to provide safe equipment here.

All that said: Yes, the requirement was essentially moved from 690.13 to 230.82(6). Also for what it's worth in the 2023 NEC this is re-iterated in 705.11 which refers back to 230 Parts VI thru VII.

My reading of 2020 230.82(6) is that a PV system can be supply-side interconnected if it has a disconnect that is listed for service and has OCPD.

Yes, but it was made further complicated by 230.46 which was deadlined to take effect on 1/1/2023.
