APPENDIX E
ROUTINGS FOR POWER-LIMITED AND
NON-POWER-LIMITED WIRING
This appendix provides guidelines for power-limited and non-power-limited wiring requirements.
The following wiring requirements shall be observed:
• Power-limited and non-power-limited wiring must be physically separated within the
control-unit enclosure
• All power-limited wiring must be separated by at least ¼-inch (6.35 mm) from any non-
power-limited wiring
• Power-limited and non-power-limited wiring cannot enter and exit the control-unit
enclosure through the same knockout or conduit.
Figure E-1 shows typical wiring for power-limited and non-power-limited circuits.
