Yeah no that's fine you'll get away with it, until you don't.I’m backfeeding 20kW to PG&E through my 100A panel/service (it never goes above 6kW in practice)

???????Yeah no that's fine you'll get away with it, until you don't.
Pretty sure it was addressed above that SDGE hates that for emergency replacement
I vaguely recall seeing stuff 1-2 years back for similar fro PG&E — panels that can accept breakers bigger than the service
Hmm interesting. I vaguely remember I was looking for the specific case of non-compliant grandfathered gas/electric service distance. It's not considered like for like for grandfathering purposes to go from 100A main & bus to 100A main with 200A busBut they don't mind my 200A panel with 200A main breaker fed by their 2 awg aluminum service drop.
Probably because the neighborhood looks like it is fed from 25kVA Pole Pig, so its fuses protect their wire. (Unless I draw 200A @ 120V?)
They did confirm I have no extra loads, asked that I notify them if adding more.
I wonder about line-side taps used to feed hybrid. You could end up with 200A main + 200A bypass drawing 400A power from 200A utility drop.
that was my recommendation but I couldnt find an electrician to do it and I don't trust my skills that much.I would have said fuck them and do the panel replacement, what the fuck are they going to do to you ultimately.
When you add in the 2 EVSE 60A breakers this wouldn't pass in a new 125a panel even though they are software configured to not exceed combined 48a. Did I mention te 50a spa? Definitely should have gotten a new panel back then.Why is a panel/service upgrade needed? The home was doing fine with 125A panel/service.

I see, did you exceed code already but now have to pull it down?When you add in the 2 EVSE 60A breakers this wouldn't pass in a new 125a panel even though they are software configured to not exceed combined 48a. Did I mention te 50a spa? Definitely should have gotten a new panel back then.
So why are you placing them on separate breakers? If they are software configured to limit to 48A then parallel them from each other. If software limiter fails then worst that will happen is the breaker will trip from overcurrent.When you add in the 2 EVSE 60A breakers this wouldn't pass in a new 125a panel even though they are software configured to not exceed combined 48a.
Run it from your 60A EV circuit via 3rd limiter so 2 EVs and a spa share the same breaker. Not to code but no one needs to know. You probably won't get licensed electrician to do it for you for fear of losing his license (so look for unlicensed oneDid I mention te 50a spa?
The Spa is configured to turn off at 10pm and the evse's only run 10:30-5am so similar work around to what you described. Good point on the evse breakers, coulda saved myself $50. But yea the right solution here is a larger panel.So why are you placing them on separate breakers? If they are software configured to limit to 48A then parallel them from each other.

Yes with the evse's it exceeds code. No one to blame but myself. Shoulda upgraded panel when adding evse.I see, did you exceed code already but now have to pull it down?
You can get Wallbox load shared + load managed to count as 6A or less IIRC, that works by gossiping the current drawn by each and also tracking the usage on the service.
You can load shed the spa (and three other things) with an LSC-04
But it's moot since utility won't let you do it. So you have to get creative with what you got. It pays to have some electrical knowledge or know an EE to help you.But yea the right solution here is a larger panel.

Agree. I have bothBut it's moot since utility won't let you do it. So you have to get creative with what you got. It pays to have some electrical knowledge or know an EE to help you.
I would have loved that solution. 3 electricians all told me the same: Sorry you're out of luck until sdge approves moving forward.Wow.
Anytime i arrive to a site with a damaged panel, i IMMEDIATELY replace the panel with one suited for the loads present, get it operational, and then have the AHJ permits pulled and schedule the inspections.
It would suck to need poco permission to buy anything before work is done. No WAY i would attempt repair of an existing panel...
Crazy.
Sure but are you still exceeding if you do the approach I pointed to, which drops your calcs to 6AYes with the evse's it exceeds code. No one to blame but myself. Shoulda upgraded panel when adding evse.
I politely disagree on what the right solution. Timing the EVSE from 10:30-5AM is not sanctioned by code as a solution (though perhaps you can convince your AHJ that your interlock scheme is sufficient. POCO does not need to be involved). Load management and load shedding (aka EVEMS) are sanctioned by code, and are a pre-engineered and listed product so you don't have to convince your AHJ, to address your problem.The Spa is configured to turn off at 10pm and the evse's only run 10:30-5am so similar work around to what you described.

This is what I don't understand -- a clear safety issue and the poco needs to get involved? Mine gives two craps what I do behind the meter if I'm not backfeeding. And if I ever want the meter base pulled to change my main feeders around (which I initially considered when I installed), they'll happily do it at no cost. Give them times, they'll show up around then within reason.Wow.

What if the power company can't support the increase from 100 to 200 amp service at their location?This is what I don't understand -- a clear safety issue and the poco needs to get involved?
That's fair.What if the power company can't support the increase from 100 to 200 amp service at their location?
They can do 1 for 1 emergency replacement, but not an upgrade.
I guess they don't have a path for emergency upgrade
Yup, I'm baffled that they won't even fast track the upgrade needed with the same size main breaker, but they are probably concerned about someone dropping back in the 200a breaker (without poco approval) that shipped with the panel and overloading the service entrance/something else local.That's fair.
My thought would be a quick approval to allow a new 200A rated panel and derate with a 100A main breaker
