Lighting and residential are not my line of work, but I have been contacted to investigate numerous tripping AFCI at a residential property and looking into some insight from MH.
I received this from an on-site facility "engineer".
What are your thoughts?
. I put in another ticket for the breakers tripping, but I wanted to let you know that I may have found the root cause. After testing, the issue only occurs when the under cabinet LED lighting is turned on. Internet research indicates that some cheaper LED transformers induce interference into the electrical line, and can cause AFCI breakers to trip, even if the lighting is on another circuit than the one tripping. However, the tripping does not happen until a heavy load is applied, like a fridge compressor or vacuum. The two factors combined are what is triggers it to trip. Can you please pass that onto the contractors and see if they can investigate? Ideally, if this is confirmed to be the cause, the solution could be to replace the cabinet LED transformer with a better quality one. I will not be home much of today, so any updates should be via text or phone. Many thanks!
