I have a shunt trip question. I do residential work and don't normally install them.
I'm installing a subpanel in the HOs new amateur radio station. After I roughed in the subpanel and EMT for the feeder the HO requested an emergency power off switch. I can't get a shunt trip main for the small QO panel I roughed in, so I got a shunt trip breaker for the GE panel feeding the new subpanel. I plan on putting 2 #12 THHNs in the EMT for the shunt trip along with the feeder and taking power from one of the branch circuits in the subpanel. Since the shunt trip wires aren't normally energized they don't count as current caring conductors, so they only count for conduit fill not derating, correct?
Thanks
Robert
