I recall reading something in an ARRL publication or newsletter that at 
least one manufacturer of AFCI breakers has addressed and corrected the 
problem of RF susceptibility.  That company is Eaton.

It is a bummer that consumers must suffer from products that do not have 
sufficient RF immunity.  If all manufacturers would 'step up to the 
plate' and accept that we live in a world where RF is present, often in 
strong fields, we would not have a problem.  Hams are not the only cause 
of RF problems - think of the problems encountered by those who reside 
near broadcast stations.  RF fields are emitted by police, fire and 
other emergency service transmitters.
IMHO, more manufacturers must be willing to design products that can 
withstand reasonable RF fields.  Of course, most consumers do not 
understand that, and the ham "is to blame".  There was a parallel back 
in the 1950s and 1960s with television interference when many TVs were 
designed with front ends and IF chains that would pick up RF on most any 
frequency, much to the consumer's dismay and blame placed on the ham, 
even if his transmissions were clean of harmonics.
It just about drove operation on 15 meters off the air because many TV 
sets used a 21 MHz IF that was 'wide open' for interference.
