This is where you'd need the real applicable code for your area, but
there is an important distinction to be made for wiring types that you
might find in the field versus what is legal (and safe) to install or
modify today.
Knob and tube comes to mind... you might see it around, but you'd
never use it as a model to do renovations or repairs. Most old wiring,
if you can touch it, should just be used as a fish wire to pull in the
new wire. ;>
