To provide some grounded outles in a couple of bedrooms, I would have to
replace the older fabric-sheathed two-wire cables with newer 14/2 wire.
To start, I've mapped out all the wiring in the house. To completely
replace wiring on each circuit would involve going into the drop ceiling
into the basement, behind drywalls, through wood floors and into the attic.
For now I can probably get by with upgrading the wiring from the circuit
panel to just the first outlet (or perhaps two) in two circuits and that
would not be much work - just in the basement and through the wood
floors - quite manageable.
Question is, is it code (our city follows NEC 2002) to upgrade only part
of the wiring to 14/2 and leave the rest as it is?
