Zinsco replacement location

I agree that if there is a safety concern it should apply old and new construction. I also don't see there is a genuine safety concern in this situation though.

Well, I don't really follow that reasoning. If there's a genuine safety concern then it applies equally to old and new construction. And it's not like when one expects to have old equipment or wiring grandfathered; you are actually installing new equipment. I've run into this sort of problem before.

With that said, I agree they should be able to quote you chapter and verse.

This would make sense for new construction or a service size upgrade but just to replace an aged panel with modern technology is difficult to understand their justification.

Unfortunately Nobody knows "why" :happysad:

I have asked many "WHY" questions from our POCO (PG&E) and I always get the same response. "It has been in the book for many years"

Bottom line is this is CA. If the POCO had filed and had approved a amendment with the Public Utilities commish with a effective date of recent then you need to follow. If not the POCO cannot enforce this requirement.

I would ask for this in writing as approved or it does not apply. It seems bogus if this is not published yet. The POCO has to publish amendments for comment.
