Parallel Cables from VSD to Motor

[TheSponge]

Hello world! Long time subscriber, first time poster. Great site and lots of great info. My question is fairly simple but I am trying to get a concrete answer with documented evidence behind it to take it to the powers to be for approval.

Is there a decrease in the maximum distance between VSD and motor with running parallel multicore screened cables to a motor as opposed to a single mutlicore screened cable? ie say 50m for 1x3core 300mm2 reducing to 25m for 2x3core 150mm2...

I know the topic has been discussed several times but does anyone have experience and links to information that I can use in the proposal for the installation output chokes?

Thanks.

The Sponge
