Power-limited Wiring Requirements

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-lim-
ited 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 illus-
trated below.
