We have a formean at work who is bent on feeding a 1900 box (4x4) for a neon light(apparently 120V) thru the same pipe run that is feeding the outside lighting (277V).
Now my question stems from this. Everyone I have talked to says it is not a good thing to do, but no one can tell me where it is in the code book or why it is not correct.
Magnetic lines of flux was brought up, but no one could give a definate answer.
Anyone know?
