I bought 3 circuit breakers for about $100. Arc fault types. I have not installed these
yet, but they are going on the remaining bedroom and older metal sheithed wiring
in the house. I don't know if they will be problematic for me. All new buildings should
have them in the bedrooms.

If using a live Christmas tree, first (even temporarily) install
them on the circuit that lights a Christmas tree. An arc fault
breaker would quash arcs that otherwise enflame the tree and take out
the house in only five minutes. Yes, a friend learned this the hard
way. She connected the tree. House and all pets gone in only five
minutes.
