Service Upgrade CA PG&E (Bay Area)

[revive]

Hello,

I have done service upgrades before but with the code changes and PG&E changes of how they are processing service upgrades, I would like to know if this install would be ok. Would love to know other alternatives or suggestions. Others have brought up using a switch gear but I think it might be overkill for this application.

Also, I read somewhere that I need to use fused disconnects. Would a meter main work if it is suitable for use as service equipment?

That is how they want it now. But it must utilize a gutter that has the slots for utility lockout tags.

What he said. ^ Seen one one like this recently with two meter mains. Should be okay. You should NOT need fused discos.

Until manufacturers update the meter packs to have separate compartments for each breaker, the trough may be the only fully compliant way to do 2-6 meters like this.

Thanks for the confirmations. Also, would you guys bond the neutral and ground at the trough or at all the meter mains? Would the grounding electrode conductor enter from the trough or meter main?

Siemens does offer compliant meter stacks now.

Not sure why it has taken the manufactures so long to deal with this change. They have known about it since before the 2020 NEC was published.

MBJ is still installed at the first point of disconnect, regardless of what comes before.

Essentially it’s no different than the N-G bond in single meter main, and a metal riser and weatherhead.

Trough can be bonded to the neutral. MBJs still required in all meter mains; meter mains are factory bonded anyways.

NEC allows either the trough or GEC taps to each meter main. I don't think PG&E has a problem with taking the GEC to the trough, but your local AHJ might call it inaccessible and make you do taps to the meter mains.
