2.12 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 NFC-50/100 with two speaker
circuits is shown below.
