Where can I find a chart or list of the diameter of common residential electrical wire that includes the jacket of common insulating materials.


Wire gauge + insulation thickness = ?

I would expect that there is a standard minimum insulation thickness for different insulation materials but are the wire manufacturs consistent in the thickness or do they exceed the minimum to varying degrees?

See the NEC, Chapter 9


Table 5 Dimensions of Insulated Conductors and Fixture Wires

Table 8 Conductor Properties

The NEC is available online for members of the NFPA. I was unable to find another location that would get us there.


Hang in there someone may send a copy of Table 5 to you very soon. ![icon_lol.gif](upload://zEgbBCXRskkCTwEux7Bi20ZySza.gif)

Use the old DOS version of the 93 code (you sent me a dozen years ago). The table is the same and it formats better in ascii.
