Because the power wiring carries high frequency electrical
pulses, it is important to run input power and motor
power in separate conduit.
If incoming power wiring is in the same conduit as motor
wiring, these pulses can couple electrical noise back onto
the power grid. Isolate control wiring from high-voltage
power wiring.
When shielded/armored cable is not used, at least three
separate conduits are connected to the panel option (see
Figure 4.4 ).
