need proper breaker

I just got rejected on my final electrical inspection for having a Square D breaker in and Arrow Hart panel. I was never able to find any Arrow Hart breakers. The other breakers i didn't get hit on were the double breakers and i couldn't find a 20A single breaker of the same type. Can anyone help as to what brand of breaker I can use here and where to find one.

Is a Murray breaker suitable in this panel?

Does this have something to do with "standards"? Why wouldn't a Square-D breaker be acceptable in this panel? Forgive my Australian naivety but all circuit breakers in Australia MUST fit into domestic switchboards. There are no "ifs or buts" with this. If you went to an Australian electrical wholesaler (or a retail store) & purchased circuit breakers along with an appropriate switchboard, the breakers WILL fit into the switchboard.

This rule, however, does not apply to switchboards that are 20 years old or older. DIN circuit breakers will not fit into "some" older switchboards.

Someone please enlighten me. Why is there a problem with circuit breakers & switchboards in the USA?

Not all breakers are listed to fit all panelboards. It comes down to some testing agency that sated that x breaker is ok to use in x, y, or z panel. If it is not on that list, it cannot be used in that panelboard.
Hope that makes sense to you.
