Nec Power-Limited Wiring Requirements For Eflowna8V Models - Altronix eFlowNA8V Series Installation Manual

NEC Power-Limited Wiring Requirements for eFlowNA8V Models:

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-limitedcircuit 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 UL Listed battery enclosure must be mounted adjacent to the power supply via Class 1 wiring methods.
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).
