Changing Main 200 Amp Breaker with Power Walls?

[SolarBob]

I need a new main master 200 AMP breaker installed in my PG&E meter box. My Tesla Installation has 2 Power Walls. How do I change a main breaker with the Tesla configuration without zapping myself.

Is it as simple has turning the Power Walls off. I suppose there is no way around losing power to the house during the change.

Any help or advise is appreciated.

Thanks

Thanks needs to be done with permits and an electrician

The danger is from the grid, not the Powerwalls. When you turn off the main breaker, the Gateway will isolate the Powerwalls and backup loads from the grid side. The problem is that the grid side of the main breaker is still hot. I think the proper way is to pull the meter, then call PG&E to reinstall it with the proper seal. You should definitely have an electrician do this for you.

If your electrician pulls the meter it is possible that the Powerwalls will supply power to the backup panel. It may depend on your configuration but your electrician should be aware of that possibility. Pulling the meter will look like a power outage to a Powerwall.

Advise the electrician you choose for this work that you have battery storage on site, and ask them how it would work on their end.

Certainly not a homeowner project in my opinion. Call a professional, and let them know your situation.

What is the issue with your current main breaker?

Totally agree, and that was my question

It is a 25 year old knuckle back breaker that is no longer made except refurbished, Cooper Crouse-Hinds Murray MD2200 Main Breaker Vertical Mount 200A.

PG&E said it looked a little worn. I am replacing it with a Siemens that will fit and work.

Just a precaution.

Maybe it is not necessary.

I replaced mine, when the electrician needed to do, with refurbished stuff. Works fine. Personally, if it is not break, leave it alone

Yes, very much not a homeowner project.

Breakers do age, and at the end of the day, you want them to work in a time of need. Personally, I was happy to do a main panel upgrade as part of the Powerwall installation just to replace 50 year old breakers.

I would hire the electrician and get it done, but I would remind him/her about the Powerwalls.

All the best,

I just hope his main service panel isn't with 36 inches of his gas riser... or it'll become the world's most painful main breaker replacement project of all time.

Only if you show up and get the lineman riled up!

In reality, old equipment needs to be replaced. PGE probably is giving a good recommendation to replace your main breaker.
