It this note still in the code?
I found this in an Article 310 note in the "HI Guide" AKA the 1968 NEC?
|13. Deterioration of Insulation. It should be noted that even the best grades of rubber insulation will deteriorate in time, so eventually will need to be replaced.|
I believe that this information could be used as a good reason to support the concerns expressed over the old knob and tube wiring systems.
Do you agree? ![icon_biggrin.gif](upload://iKNGSw3qcRIEmXySa8gItY6Gczg.gif)
