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.
*Note: In certain applications, an NAC (power-limited circuit) could be adjacent
to a releasing circuit (nonpower-limited without supervision kit REL-4.7K)
