3 phase kiln

[Victor]

I have to install the wiring this week for a three phase 8.8kw kiln with a 25m cable run, could someone let me know what size mcb and cable I should use, as my mind has gone blank, must be old age creeping in.

Thanks in advance for any assistance given

top of head guesstimate is 12A/phase so 2.5mm on a 16A MCB. VD needs to be calculated according to the length of the cable run.

^^^^^ Yep, 12.7A per phase.
