Now lets see. Here in Massachusetts, I know, I know, it is what it is...
Anyway, trying to make a good rule of thumb for arcfault vs GFCI requirements in residential dwellings, such as:
GFCI:
1) 2 20A GFCI circuits in kitchens
2) at least 1 20A GFCI available in each bathroom
3) unfinished basement receptacles
4) all garage receptacles
5) all outdoor receptacles
AFCI:
Everywhere else except:
unfinished basement receptacles (GFCI there)
what about these:
range? 120 or 240?
refrigerator?
furnace?
AC condensor?
sewage ejector pump?
