Discuss cable selection 600amp 3 phase in the Commercial Electrical Talk area at ElectriciansForums.net

Hi wondering if anyone has any advice on what type of cable would be best.

I need to run a 600amp 3 phase feed with neutral using single core with power lock connectors for just under 50meter across the open floor with short sections in cable ramp, from this it will be broken down into 3x 125amp 3 phase connectors each taking just under 100amp per phase.
This will feed some 3 phase equipment and also break down into several single phase supplies.
For shorter runs of this I have used H07RNF at 120mm, but wondering on sizing for this length run and if there are alternatives to H07RNF that would give us the same current capacity still be flexible enough to move and keep with in our voltage drop.
Thank for any help.

The OP has asked a question there is no need to drill him over his qualifications. The offending and now not relevant posts are gone.

No offence taken quite happy to be asked. my questions is more of a general enquiry, in case I have missed a type of cable that could be use. Your link to the cleveland trirated is for panel wiring cable is this not really suitable for laying on the ground in exposed areas?

Glad you understand but these questions can quickly throw a thread off course and at times stop new members pursuing the thread.
Yes tri rated conductors would require additional protection.

Tri rated isn't suitable unless the entire run is mechanically protected in trunking or similar.

You need to do some calculations taking volt drop into consideration but it will be 500 to 630mm. I would suggest contacting Cleveland or Eland cables for an accurate sizing.
