Arc fault breakers have earned a reputation for being finicky and trip happy, and all the while being difficult to troubleshoot. Possibly that is overblown. Hopefully, now that the technology is about a decade on the market, the manufacturers are coming to terms with the issues, assuming that they existed.
What concerns me is the concept of using a two pole arc fault to protect an old three wire circuit. It just seems to me that as squirrelly as arc faults may be, using them in a three wire circuit is going to double my client's grief.

Has anyone got practical, recent experience of installing similar equipment to protect 60 year old three wire circuits?
