2.7 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" (6.35 mm) away from any nonpower-
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 NFW2-100 is shown below.
