RDK's in Canada, but as far as the NEC, control wiring is permitted to be protected by a higher OCPD

Table 430.72(B) allows, where the control wires extend beyond the enclosure, as in this case:

45 Amps for #14
60 Amps for #12
90 Amps for #10
and 300% the value specified for 60° conductors (in 310.16) where over #10

Where they do not extend beyond the enclosure, the protection can be up to:

100 Amps for #14
120 Amps for #12
160 Amps for #10
and 400% the value specified for 60° conductors in 310.16 where over #10


I never realized that the Code allowed me to do this. It could be fun arc welding here and there and blowing up stuff where i would normally just take out a control fuse or two. Thanks for the explosives training!
