Help With Square D Parts, If You Please....

[Seven-Delta-FortyOne]

We don't have any Square D up here, its all Eaton, so I rarely work with it.

I have a 200A Homeline with the 4 space backfed breaker that I need to install an ATS. I want to move all the branch circuit wiring out of the meter/main, put them in a sub panel, and reuse all the breakers.

I'll feed the ATS from the load side of the MCB.

I use the Eaton BRPFS225 lug kit in these situations, like this, when I'm working with Eaton:

Eaton BRPSF225 - New Sub-Feed Lug Block$126.29Coast to Coast BreakerFree by 5/2130-day returns (most)

I'm looking for the same for the Square D, and I think I found it, but I just want run it past the guys who work with SD first. I found these, one looks like a feed through lug kit, one appears to just be a 200A 4 space breaker, which is actually cheaper than the feed through kit:

Or the breaker:

That sub feed kit will work the same but I usually can't get a sub feed for less than a breaker. If I were you just go with the breaker because of cost . Does the metermain not have feedthrough lugs already?

 

[kwired]

Is your Homeline unit the meter main you mentioned?
And if so it apparently doesn't already have feed thru lugs as letgo asked?

 

[letgomywago]

Is this the 30 space metermain the wide one or is it the half a buss long one with 20 spaces

 

[Seven-Delta-FortyOne]

It’s this one. No feed through on it.



The breaker is cheaper than the feed through kit. I just don’t have the experience with them to know if those 4 space breakers only fit on the one spot where the Main Breaker sits, or if I can put another one on somewhere else?

Half buss 20 space.

 

[wwhitney]

Half buss 20 space.

HOM2200BB needs to be listed for the panel you use it with, and IIRC it's not listed for older panels of the style you have. You need to check the panel label and/or look up the model number on Schneider Electric's website, they may have an FAQ about which panels you can use HOM2200BB with.

As for where to install it, my understanding is that it is designed to be installed at the bottom right. It has diagonally pointed lugs, which provides for more wire bending space when it adjoins the clear space at the bottom of the panel.

I'd look into the subfeed if I were you on this

 

[letgomywago]

They'll bite anywhere on the panel it's not limited to the middle like main breakers are often on those.

HOM2200BB is not a main breaker, the BB means "branch breaker." I believe HOML2225 is subject to equivalent limits as HOM2200BB.

See https://www.se.com/us/en/faqs/FA101877/ which is titled "Can the HOM2150BB, HOM2175BB, HOM2200BB, and HOML2225 be used in CSEDs?"

Instead of the breaker? Why’s that?

You don't want to run into the issue of it potentially not being listed for that panel on the label.

 

[wwhitney]

You don't want to run into the issue of it potentially not being listed for that panel on the label.

Same issue applies to HOML2225.

I have a pic of the label, but I don’t see any place where it lists allowable breakers. Unless it’s that smudged area I can’t read.

That label says the maximum branch breaker size is 100A.

 

[Seven-Delta-FortyOne]

That label says the maximum branch breaker size is 100A.

Found it. Thanks.

Lug kit it is then.

 

[wwhitney]

Lug kit it is then.

As far as getting a listed combination, both the lug kit HOML2225 and the breaker HOM2200BB are a no go. The SC2040M200C was released well before those products existed. For new panel designs, SE will test them with those lug kits and breakers as part of their listing. But they have no incentive to go back and test these old products with the new lug kit and breakers, so they will never be a listed combination.

For more information, see this thread (start at post #16 to avoid some of the extraneous details), in particular post 42:

As wwhitney said, the bus fingers were tested with 100A max plug-on connections, parallel connections were not evaluated.

 

[kwired]

That label says the maximum branch breaker size is 100A.

Does that apply if you have a breaker (or sub feed kit) that takes up 2 spaces per pole?

These types have output lugs that are angled so that wire bending space isn't necessarily an issue.

Might need to look at instructions that come with the breaker/sub feed kit as well to determine if it can be used.
