Can I run low voltage shielded control wires in the same conduit as line voltage control wires?
The air handling unit we are to wire is 3ph 480. This is stepped down to 115v for 8 control wires, and the 115 if further stepped down to 24v for 2 shielded control wires. The drawings call for one pipe from the wall mounted controller to the ceiling mounted unit. Can I in this instance run line and low voltage in the same pipe?
That is, is the shielding on the two wires protecting them from induced current (which is my understanding as to why we don't combine line and low voltage wiring in a box without a barrier)?
Thanks for any comments.
