Hello,

New here, but hopefully someone can help...!

We have been tasked with installing a number of very small pumps (21 in total) on a large site. Running individual cables to the 7 areas (3 x 1.0kW / 400V / 3phase / DO.L. pumps in each area) where these pumps are located would be expensive.

I would like to install a 3-phase & neutral ring main but I'm unsure how to calculate this for volt drop / current carrying capacity. If I were to proceed this way the end to end (circular) length of the ring would be around 2000 metres...

Any suggestions?

Cheers, Sumo
