Greenfield

[j rae]

Is there a code on the length you can run greenfield?? I believe it has to be supported 12 in. from the box and every 4 feet. Do the ckt. conductors have to be numbered ?? Can you run greenfield in a hospital ???

The only limit on the length of FMC is for 3/8" which is 6'. Obviously there are other applicable code sections like use as an EGC, support, number of bends, etc.
