Our house was built in 1960 and had a 100 amp fuse panel with 8 plug spots and 4 cartridges. It was replaced 35 or so years ago to a whopping 24 breaker panel that got eaten up with a kitchen renovation. Of the 24 breakers 20 are single phase 15 amps.
If I read it right those would have to be AFCI type now at $100 more each so an extra $2,000. Are the regular breakers that big a safety risk?
Personally, I have no problem with quality properly selected fuses with copper bus bars. Aluminum bars, not so much.
The demands to make everything 100% safe is driving up costs and eliminating the Darwin effect.
How many of these safety devices are being lobbied into law to push up sales numbers. Maybe just let the herd cull itself.
Some of the demands are arguably counter productive.
