Changed my mind about those fancy arc fault breakers after a 3-month apartment rewire

Did a full rewire on a 12-unit building downtown. Installed Siemens arc faults on every circuit like code says. Had 8 nuisance trips in the first week. Tenants were pissed, landlord was calling me every day. Spent hours swapping them out for regular breakers and adding AFCIs at the panel instead. After that, zero trips in 3 months. I get the safety thing but these things are way too sensitive for older wiring. Anyone else find a brand that actually works without false tripping?

Nuisance trips usually mean you're mixing brands with older wiring, not a breaker problem.

My dad had an old house once and we just swapped out the whole panel. Stopped having those ghost trips instantly.

Nuisance trips happen with all kinds of wiring, not just mixing brands.
