Installation and Configuration UL Power-limited Wiring Requirements
14 CHG-75 PN 51315:A 08/01/01
2.5 UL Power-limited Wiring Requirements
Power-limited and nonpower-limited wiring must remain separated in the cabinet. All
power-limited circuit wiring must remain at least 0.25” away from any nonpower-
limited circuit wiring. Furthermore, all power-limited circuit wiring and nonpower-
limited circuit wiring must enter and exit the cabinet through different conduits.
Examples are shown in the following illustrations. 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.
