flow through main breaker?

18 years ago

I am building a new house. Owner-builder.

The power company guy was here today.

We discussed where to put the meter pole, etc.

Meter pole will have the PECO power lines spliced to my 30 inch pigtails then enter the weatherhead and come down to the meter, then down through a small jumper section to the OCPD. Then down underground and horizontal to the main panel in the house.

This is near my wellhead and he suggested that the main breaker OCPD might be a "flow through main breaker panel" and I could go direct with a smaller breaker to the wellhead and supply the pump. So, not just the 200A main breaker but a 20A breaker labeled "well pump".

I think he said "flow through main breaker panel".

So, what is the exact term for this type panel for shopping purchases? Any recommended model numbers? Thanks.

Feed-through panel.

Yes, typical for your installation.
They have lugs out the bottom for the full service capacity to go on to the house, and several branch circuit breaker spaces for local use.

Exactly what we did with my installation, except that we took two breakers- one for the well pump and one for the heat pump.

Maybe some of you might cringe but I went to Home Depot tonight and bought a feed-thru breaker. The only one they had. A 200 amp GE Powermark Gold Load Center. TM820RCUFLP, $109 plus tax. More spaces than I wanted (8 spaces). Maybe I can also rig a local outlet for convenience or feed my septic pump from here? Any comments on that? I saved the receipt and can get a refund if I don't mess with any of the knock outs. It is 28-11/16" high, which seemed kind of big but that doesn't matter does it? It was very roomy inside. Did I do OK here or should I order something online better?

I also bought some other materials to prep for the meter pole installation. PVC 2" weatherhead, acorn clamp for the ground rod, PVC clamps. Tomorrow I bring my utility trailer and buy the 5/8", 8 foot CU ground rod and some 2" sched 40 grey PVC. The power company still has to come and cut trees and then start installing poles...
Thanks guys.

I would say that size is fine. You have to wrestle the 2/0 conductors (or even bigger depending on the distance to the house) in it and need the bending room. It would definitely be smart to add a weather proof box with gfci and in-use cover. Might even get a double gang outdoor box with 2 gfci's on 2 breakers if it is a spot where multiple tools or future equipment might be handy.
