Eaton Giving up on Notching CTL Bus Bars?

[jim k]

Has anyone heard that Eaton is dropping the convention of using notched bus stabs to accommodate tandem breakers? The installer of this panel insists that non-CTL tandem breakers can be installed in this panel at any stab location, though none of the stabs is notched.

If this is the case, doesn't anyone have any documentation from Eaton?

If this is the case, are other manufacturers likely to follow suit?

This started with them like 3 or 4 years ago

Thanks. Are other manufacturers following suit?

Non that I've seen. Most have added more than the 42 circuits. My favorite cheap siemens 200amp is a 3048

Correct, Non CTL breakers do not have the rejection clip and can be installed in any location on the bus. CTL on the other hand have the rejection clip and can only be used on notched bus locations.
Non-CTL breakers (ie BR1515 $27) are a lot more expensive than the CTL type (ie BD1515 $16) though.
Also caution should be had to avoid overloading panel with a lot of non-CTL breakers,

Eaton listing seems to max at 42. Others seen as high as 80. I do like the Siemens as I can get tandem AFCI for them.

Siemens Line card shows UL Type QTA

Tandem AFCI breakers without the rejection feature can be installed in any panel that lists that breaker type or where a substitution letter exists for that breaker type

Has anybody seen what a substitution letter looks like?

You might want to take a look at this thread. I find the entire issue to be somewhat confusing due to the markings on non-CTL breakers.

Eaton and Non-CTL Circuit Breakers

So I purchased one if these panels (BRP-20L-125) because I had a bunch of Eaton BR circuit breakers left over from a job and need to add a sub-panel in my garage. The label and the specifications state that this is a 20/40 panel, 20 slots and 40 circuits. When I opened it and looked at the bus...

Thank you, I see Eaton indicates Non-CTL doesn't have the rejection clip and would be compatible with the BRP.
