Would like to talk to KBsparky or anyone else to see if anyone has parts for the above square d load center . I just replaced the main breaker today however I found that one the buss bars under the main had been arcing, the reason for replacing the breaker. The other buss bar is ok. On a tight budget or would replace panel. Any help would be greatly appreciated.

That panel doesn't cost that much to begin with. You could just buy a new one for the part you need.

You could also just buy the new one and change the whole thing out.

I'm not sure how tight your budget is, but for around $50.00 you can buy a new QO20M100 panel at Home depot. Strip out the parts you need and keep the rest for future spare parts. As far as finding replacement parts I can't help, these panels are basically disposable and we don't repair them, if there is an issue we just replace.

I'd do as EBFD6 suggested. Just buy a new panel, leave the original box as-is, and replace the interior.

You could likely buy just the interior at a Square D wholesaler, but I'd bet it would cost more than a whole panel.

A QO20M100 is an obsolete number, and I do in fact have a couple of those panel guts around the shop. Someone else from here wanted to buy one from me last month, but never completed the exchange.

The other replies here are referring to the newer type of panel, the correct catalog number is QO120M100. And they cost $90 or more, depending on which store you are shopping at. :whistling2:

The mains are completely different in each of these:

Old main breaker part number is Q1-2100TF
New type main breaker is QOM100.

They are not interchangeable. :no:

Yep discontinued panel as Sparky has detailed. The interior (if you can find it) is part# QON20M100. Graingers shows a limited supply of these interiors but you must call them to locate the store that still has some on inventory. Craigslist has a few panels like yours. My Advice ... buy a new panel or see if KBSparky will sell one of his to you.

Ok Thanks I will get back to you.I am awaiting word from my insurance company if they are going to cover a new panel or not,storm damage,and I will let you know.If no insurance coverage I will definitely be interested,easier than changing the whole panel.Also,I don't want to be a pain in the a##,but the interior guts you have ,do you happen to know if the neutral and ground strips are on top of the main. I have seen pics of different variations of the QO20m panel and a lot of what I have seen has them on the side. I need them on the top otherwise wiring will turn out to be a little short trying to relocate everything. If necessary I can send you a pic of what mine looks like but I am sure you already know what I am talking about. Thanks again. Paul

great pic

Hello,super pic,Thank You. From the main up looks just like mine,but where the breakers go looks a little different from what I can see. Mine has bus contacts that are open around them on every other one and then there is one in each area of the black plastic,alternating from which side the supply comes from. Maybe its just the angle of the picture. I have a total of 10 on each side with a total of 20.Could be i'm just not seeing it right,but the rest looks great. Thanks Paul

Hello.I think I now see from this pic why mine looks different.This is what mine is supposed to look like,but doesn't. Plastic is all burned around where contact goes on to bus on mine where breaker rests on.I have 5 or 6 spots where the bar is damaged and the its stressed. On the breaker,is it still a Q1TF type? What is different about them,age,type,that you did a swap and sold the one that was on it. The changed one looks a little older with different labeling,is that all ? Just got a call from the adjuster,I should know soon whats going on. Thanks Paul

Yes, that is a Q1-2100TF breaker. The other one looked cleaner due to its being installed in an unused warehouse for 25 years, and only had one circuit connected to it. The cover never got opened, and it was basically still "new" in appearance. The guts are from that same installation.

You could also use a Q1-2100 without the TF if you wanted to. The difference is both the line lugs are on one end of the breaker, instead of the top.

Yeah, just got the notification. You didn't specify in the PayPal transaction what it was for, but I thought it might be for the Square D guts, discussed here.

I'll get it out to you tomorrow.
