   All wiring in a circuit except for the leads that are part of a device or fixture must be of the required gauge or larger. Different size wires may be used in the same raceway so long as they are all insulated for the maximum voltage of any of these circuits. The Code gives rules for calculating circuit loading and maximum ampacity.

   Today, porcelain standoffs are still commonly used with bare-wire electric fencing for livestock, and such porcelain standoffs carry far higher voltage surges without risk of shorting to ground. In summary, K&T wiring that was installed correctly, and not damaged or incorrectly modified since then, is fairly safe when used within the original ...

   The temperature rating of a wire or cable is generally the maximum safe ambient temperature that the wire can carry full-load power without the cable insulation melting, oxidizing, or self-igniting. A full-load wire does heat up slightly due to the metallic resistance of the wire, but this wire heating is factored into the cable's temperature ...
