A friend has a breaker box with Cutler Hammer breakers. in a 125 Amp
box

I saw some 20 and 40 amp breakers but no main breaker.
One of them is BR2020 for the 20 amp breaker.

Where is the main breaker located located?

Thanks,
Andy

You're not giving much information. Is this installed or sitting on his
kitchen table? Is it installed as a main panel or sub panel? There are a
variety of breakers that will work in the panel, including those that you
listed. Assuming that this is his main service panel, and you are concerned
that it doesn't have a main breaker in it, it may be because the main
breaker is located separately, and possibly outside, and possibly an
integral part of the meter box. It is also possible that it is a split buss
panel with main breaker section on the top, which would have spaces for up
to six double pole breakers.
