UL Power-limited Wiring Requirements Installation
3.7 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 and nonpower-limited circuit wiring must enter and exit the
cabinet through different knockouts and/or conduits. A typical wiring diagram for the Distributed
Audio Panel with two speaker circuits is shown below.
