OK, WOW, just reviewed the 2020 NEC changes scheduled to take effect this year.
I'm asking if I'm interpreting the changes correctly:
1) Whole house surge protection. Required either between the meter and load (type 1) or on the load side (type 2)(in the panel?)
2) EVERYTHING needs GFCI now? Including all 240 volt circuits (dryer, water heater, range, AC, heat pumps, well pumps, fixed appliances (dishwasher, garbage disposal, microwave, etc.) ??? Given the previous AFCI protection does that mean for circuits requiring AFCI protection now require "dufees" (Dual function GFCI & AFCI) breakers?
3) Exterior disconnect required on all structures. I think pulling the meter on the main service would suffice for the house, but would outbuildings now require an exterior disconnect? I think so based on what I have read online.
4) When does the 2020 NEC take effect?
