I'm doing a survey of a fire protection control
circuit of a data center. I found that one(1) of the
three Leibert Power Distribution Units(PDU) was not
connected to the shut down control if the panel were
to activate. My question can a pair or #14 THHN be run
in the same conduit as the 480 Volt power feeding the 150AMP PDU . These wires are
across a set of dry Normally Open (N.O.)contacts that
when closed complete a 24 Volt D.C. circuit that
activates a shunt trip which in turn trips the main
breaker on the PDU eliminating power to data center
equipment. If you have an answer for me or were I can
go for an answer I would appreciate any help
