Amp reading on 2400V motor
(OP)
We want to measure the amp load on a 2400V motor. Can we use a fluke clamp on meter that is rated for 600V? If not, how would you suggest we obtain this data?

Most existing 2400 V circuits are unshielded, so I don't advise doing this unless you take precautions and wear gloves, along with PPE. As Pete mentions, you can get good results clamping on the CT secondaries and it is MUCH safer.

Under the new UK rules there is no longer 'medium voltage'. If it is below 1000V AC or 1500V DC it is 'low voltage' and if it is above those values it is 'high voltage'. But yes, I do miss the MV term and use it fairly frequently in conversation. I'm just trying to adapt to the new way of doing things. In my defence I plead the following: http://

That is what is said at bottom of the document.
I had no idea.

On the other hand, that choice/decision has very little to do with any 600vac rating of the clamp-on that I know of. Can someone explain the significance of this rating?

"If shielded and grounded both ends, you wouldn't get a good measurement."
I doubt that a motor cable ever has individual shields on each core. Are there such cables?

The voltage rating applies to situtations where the clamp is placed around an uninsulated live conductor.
