ECN Forum Forums Code Related Discussion NEC & other Code issues Can I run MC to emergency lgts & exit signs?

Yup thats what I did but, Theres no EGC in the exit light.
It came to me last night I should run seal tight.

I am curious on the reasoning for not being able to run MC to the plastic exit sign. The MC is bonded to the j-box its being fed from.... So anyone know the reasoning for this rule. Its certainly in the code book.

MEC 314.3 is the same as NEC 314.3
