Nec Power-Limited Wiring Requirements - Altronix Maximal11FDV Installation Manual

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). Optional battery enclosure must be mounted adjacent to the power supply.
For Canadian installations use shielded wiring for all connections.
Note: Refer to wire handling drawing below for the proper way to install the CM or FPL jacketed wire (Fig. 4a).
