Nec Power-Limited Wiring Requirements For Maximal7D - Altronix MaximalD Series Installation Manual

NEC Power-Limited Wiring Requirements for Maximal7D:

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 differ-
ent 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. 7a).
