You should also heed the following guidelines:
Use separate paths to route wiring for power and devices. If power wiring and device wiring
paths must cross, make sure the wires are perpendicular at the intersection point.
NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit.
To avoid interference, wires with different signal characteristics should be routed separately.
Use the type of signal transmitted through a wire to determine which wires should be kept
separate. The rule of thumb is that wiring that shares similar electrical characteristics can be
bundled together.
Keep input wiring and output wiring separate.
Where necessary, it is advisable to label the wiring to all devices in the system.
