How many houses are there with a 30A 120V service? You will probably
have to look real hard to find a K&T house that has not had major
additions. (It should probably be on the national registry of historic
buildings.)

yet bud concludes K&T is fine despite the fact it must of been
altered.

hey I have the NEC agreeing with me while bud has a few exceptions
which may have changed by now, since its been a lot of years since
buds illinois report came out.

and state farm sopped surcharging K&T they just refuse to write new
policies
