Ayrton:
Just an FYI, there is no such creature (that I know of) as an AFCI 'tester'.
AFAIK, the only recognized 'test' is via the test button on the AFCI CB!
The last time I spoke to Sq D re: the CH breakers; they answered very quickly...NO. Speaking to CH, they said "the breaker is recognized for use in SQ D panels"
Can you get another 14/2 up to your splice box?
