Power-limited and non power-limited circuit wiring must remain separated in the enclosure. All power-limited
circuit wiring must remain at least 0.25" away from any non power-limited circuit wiring. Furthermore, all
power-limited circuit wiring and non power-limited circuit wiring must enter and exit the enclosure through
different conduits. One such example of this is shown below. Your specific application may require different
conduit knockouts to be used. Any conduit knockouts may be used. For power- limited applications use of
conduit is optional. All field wiring connections must be made employing suitable gauge CM or FPL jacketed
wire (or equivalent substitute).
Note: Refer to wire handling drawing below for the proper way to install the CM or FPL jacketed wire
(Fig. 18a, pg. 19).
