Do I have to remove all of the dead knob and tube wiring?


Are you sure you want to replace it? Really. K&T is a very good
wiring system. You would not put any new in, but assuming what is
there has
the capacity for what you need, why replace it?



Agreed. Seems most of the impetus for replacement comes from anal
insurance companies and their threat of policy cancellation.


What about old 60 degree Romex that was commonly burried in insulation
and carried both conductors together. Both conductors generated heat,
and were adjacent if insulation failed. Maybe Romex should be replaced.

IMHO insurance restrictions on K&T are largely the latest redlining scheme.



Wellllll... most K&T is not rated to have insulation blown around it,
so that pretty much mandates replacement in exterior wall cavities, in
my book.

is a report to the Illinois Department of Commerce and Community Affairs
on adding building insulation around existing K&T wiring. No record of
hazard was found in the large number of K&T installations that had
insulation added around them. At the time of the report, adding
insulation was permitted some places, not in others.
