which I think is 90C rated, as are the breakers, I think

No, the breakers and any terminations will be rated at most 75C. But at the terminations you don't have to apply the derating factor (they are not in the ceiling). So 2/0 Al has a rating of 135A at 75C terminations.

The "Net" is a good description, except it's called a feeder, not a service. The service is just from the utility to the first disconnect.

Ah.. OK. I thought I'd read Homeline breakers were rated at 90C. Guess not, and it appears to not matter so...

Thanks for clearing up my wording, and for all you help!
 
And you dont put Homeline breakers in a GE panel. Rarely can you change breaker families even if they seem to fit. So if you like homeline breakers, buy a homeline panel. If the panel is GE, use GE breakers.

The stabs of the GE are different sizes than the Eaton or homline, think GE is slightly thinner stabs on the bus, and the HOM breaker would set slightly loose in a GE panel, and opposite is true trying to put a GE into a HOM panel would almost require a hammer. (Seen it recently, stopped the pool installer guy as he's hammering a GE breaker into a HOM panel with his fist, it took a pry bar to get it back off. Supply house told him "it would fit". He had to wait 2 weeks for a HOM to come in.)

I was going to mention that, but I think the GE panel is the sub panel. Good to point out though.

Personally I think the op should let the electrician do his job. IMO these hovering paranoid non-trusting clients are the worst!
 
Electro:
It's true, you'd likely not do well on jobs for us. Best of luck to you none-the-less.

Panel Commentators:
I was about to screw up. Hopefully whichever guy gets the job just laughs and corrects me, but still - bad on me.

On the other hand, somehow Eaton makes breakers that fit many panels. Heck, I think I have an Eaton in whatever generic panel is in my own house. How, as an example, a CL250 fits a Homeline, GE, and Murray I don't know. Likely just something intrinsic to your trade I don't know, and I suppose I don't need too. Anyway, I again defer to experience - you tell me: I'd rather not suggest proprietary things if I don't have to. Product shortages are a solid real world example of why. So....

May I ask what panel accepts multiple mfg (looks like "listed" is the key word) breakers? Cost sort of matters, but this isn't likely a significant cost anyway. Cheap crap is a no-go, and flexibility, in this case breaker selection/access/availabilty has a value.

Thoughts? What panel (and associated breaker options) do you think I've described?

Update:
Electrician #1 had to re-schedule. Something went sideways on him and he needed to move to tomorrow. NBD, this happens with smaller shops, and since I prefer owner operated shops that bill T&M for residential work I try to roll with it. #2 is next week, and that's all I'll talk to unless I get the feeling neither of them have the skills/workmanship I'm looking for.

Thanks guys!
