AFCI breaker installation in older homes. With so many changes, older generation breakers may not be up to date or they simply have wear from regular or excessive use and might easily be resolved by upgrading to a new AFCI. Wires are often folded (jammed) into boxes quickly, and if the wrong two wires make contact, they can trip an AFCI. That is a valid design decision, for voltage drop issues, if wire was free.
