2.10 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 for the PANEL is illustrated in Figure 2-3.
