UL Power-limited Wiring Requirements
2.3 UL Power-limited Wiring Requirements
Power-limited and nonpower-limited circuit 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 knockouts and/or
conduits. A typical wiring diagram for the UDACT-F is shown below.
