Question

[sparky1118]

So I’m starting a job wiring/bonding an in ground pool. The home has a 400 amp service. One panel is located in the garage probably an easy 200’ away and a pain in the ass to get to. The second one is located just inside the basement next to where the pool equipment is going to be. The panel closest to the pool equipment is maxed out 100% and has a generator/solar wired into it. So I cannot tap into that. I have attached a picture to show you what I have to work with. Originally I was going to remove the disconnect breaker for the far panel and install a 200 amp panel. However that being said I cannot do that. Since I have to have a disconnect for the far panel since it’s SER running in the house. I don’t think I can do the 200 amp panel since I honestly don’t think I’ve ever seen a 200 amp breaker besides a main breaker. If that makes any sense? I’m just curious if anyone has any ideas as to how I can do this without running back to the other panel. Thank you in advance.

A feed-through panel?

I did a swap years ago to get more space with a "feed through" panel. It had lugs on the top and on the bottom. You could swap the panel out and set up another tandem panel at 200A. ??

Nice Larry! Posted at the same time!

I was thinking one with a main breaker, branch-circuit spaces, and load lugs on the bottom.

Sort of a combined main breaker disconnect and sub-panel in one enclosure.

I did a MB instead of a ML on the second panel. It made sense for the application to shut down the second panel. I think code wise you could use a ML on the second panel? Is this correct?

I was thinking of a feed through panel to be honest. Question since I’ve honestly never used one before. Killing the main breaker in the panel would that also kill the taps at the bottom for the other panel? That was my only thing since I haven’t used one I don’t know.

Yes. Example:

The main kills the power all the way down the bus, including the feed-through lugs. That's how mobile home services are, the service disconnect is outside, the FT lugs carry the feeder to the inside.

I find it interesting that either Code required or the electrician decided to provide "Dual Power Source" labeling even though grid-interactive solar will also shut down as soon as POCO feed is cut. It is not really an independent source representing a shock hazard.

Thank you I will go this route
