Panel make-Cutler-Hammer
Cat# 4030
120/208V 125A 3PH 4W
Circuit breaker class type list: class NI, CH, & CH2100 safety breakers
Approximate year of panel installation: 1964
Type of breaker needed: CH115GFCI
Type of breaker purchased: CH115GFCI

The breaker purchased will not not seat onto the bus properly.
Does anyone know where we can find or maybe have the part number of a GFCI breaker that will work.

if this is easier, pull the circuit you want protected into a box next to the panel and install a receptacle, cheaper than a breaker.

If you can get a regular breaker that fits, you could alway set a small sub panel. Then you can use a GFCI that is designed for the newer panel.
Maybe a small 4 circuit sub?

Only time I ever hit a snag with CH breakers, it was in the "wrap around" that holds the breaker at the connection end. Seems like it was a metal lip that protruded into the space. I honestly can't remember, but if altering the panel isn't an option, then I agree with setting a sub-panel to accept the newer breaker.
