two older breakers in a panel (maybe 20 years old) feeding a box directly above the panel which had two new breakers: one 20 gfci breaker and another 20 breaker.
Is this done frequently because one cannot find the old stlye breakers.
I can theorize where this might be done where a GFCI style breaker is not available for the older style panel. I expect that the same thing may happen with AFCIs.
