Square D 100 Amp Main

[C3PO]

The picture Dennis posted is that of a Q12100TF (as in top feed). It went across the entire width of the panel and the conductors entered the 'side' of the breaker. Replacing this with a standard QO2100 is possible except your incoming line conductors will probably not be long enough.

When the Q12100 was obsoleted, back in the 80's, it was replaced with the QO2100. I do not recall that a QO2100TF was ever produced unless it was as a special 'form and fit' replacement.

In the old style panels the neutral bar would not be in the way, it would have been located at the end of the panel, usually between the breaker lugs.

I was hopeing you would chime in. You have forgotton more about Square D and it's "product history" then I will ever know. :smile:

I think the OP said his had the lugs on the same end,so he shouldn't have a wire issue. I used to have one of those laying around my shop somewhere.

Someone is wrong.

The part number would be an SK5669, but it was used only in panelboards never in loadcenters. Even then, it was never required for replacement purposes.

Thankyou ....

Minor correction, it was used in 400A loadcenters because those used panelboard 'guts'.
