NEC Power-Limited Wiring Requirements for Maximal37E and Maximal75E:
Power-limited and non power- limited circuit wiring must remain separated in the cabinet. All power-limited circuit wiring
must remain at least 0.25” away from any non power-limited circuit wiring. Furthermore, all power-limited circuit wiring
and non power-limited circuit wiring must enter and exit the cabinet through different conduits. One such example of this
is shown below. Your specific application may require different conduit knockouts to be used. Any conduit knockouts
may be used. For power-limited applications, use of conduit is optional.
All field wiring connections must be made employing suitable gauge CM or FPL jacketed wire (or equivalent substitute).
Note: Refer to wire handling drawing below for the proper way to install the CM or FPL jacketed wire, (Fig, 6a).
