Advantages/disadvantages of VFD cable.
Advantages/disadvantages of VFD cable.
(OP)
Is it a signficant advantage to use VFD cable (such as Belden 29502)?
What are the advantages or disadvantages compared to just using individual THHN or eqiv. conductors.
I'm running VFDs to three 11KW (15HP) motors through the same 2" conduit (under concrete floor) along with conductors for a fourth 4KW (5.3hp) motor not on a VFD. Conduit is 19' (6M) to a junction box that breaks out to the four motors.

Its better to have the wiring ran in seperate conduit or in the same conduit but with VFD shielded cable.

STEEL conduit will certainly help reduce EMI from the conductors (if it is properly bonded), but PVC conduit, even in concrete, will not reduce the EMI much.
