2.5 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” (6.35 mm) 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 is
illustrated below.
