I live in Sparks, Nevada and the 2011 National Electrical Code applies to me.
I am installing a new bathroom fan on a separate circuit from the existing bathroom circuit. I want to change the existing light switch's 1-gang junction box to 2-gang to accommodate the new fan switch. However, the existing wiring on the old switch is not up to code (the wires are not long enough to extend 3" outside the box and the sheathing does not extend 1/4" into the box).
Will the inspector require me to bring the existing wiring (which I am not modifying, just putting in a new box in the same place) up to code to add my new switch?
