I make all the electrons line up for their Flu shots
I got a call from a customer whom I rewired her 3 bedroom house for a while back. She had hired a PV company to come install panels on her roof, and as soon as the job finished she started having issues with the afci's in the panel tripping randomly and consistently. The afci's have not given trouble in the past. She calls the PV company about it , they send the "electrician" back to the house to troubleshoot the problem. Solution= removed the afci breakers and substituted in standard breakers. So she calls me and tells me what has transpired. I call the pv company and talk to the "electrician" who tells me it is just a test for a week or so to see if the system will trip standard breakers. WTF? How about getting up on that roof and discovering where your connections are loose, or which microinverter is causing the effect, or perhaps are all of them in union causing this problem. The reply is " your afci's are not compatable with our panels". My reply is "our afci's are mandatory, and your panels are not, so if you want to collect your money, I suggest you fix your problem, because the city inspector will take a really dim view of you pulling the breakers , since they hate all the pv pirates that now flood our city. I feel for this guy, I kinda feel he is right, it is probably a defect in the afci's that is really at the heart of the problem, but I feel pulling them out is no solution. What ye say?
