My read of the relevant section of the NEC (770.133) indicates that where
there are circuits under 1000V, the cable I'm going to pull (non-conductive
optical fiber cable) is allowed. I'll check with my electrician before I
proceed, in any case, as (in the same section) I can't have the fiber in
the electrical panel/box itself.
