Three Phase Load Calculations

[enlighting]

Evening Chaps,

I need some assistance with regard to a three phase load calculation.

Back story here is im fitting a new supply cable for an industrial three phase oven and need to know what the max load will be per phase to ensure adequatley sized cable is is fitted. The cable run will be 80 meters on ladder.

All ive been told so far is that the oven is 80Kw.

Am I correct in thinking the following formula is the one to use?

I = 1000× P / (√3 × PF × V[SUB]L-L[/SUB])

looks like you're stuck with 25mm, then.

Yeah thought as much. Cheers for the assist.

On an unrelated note, since your an experienced memeber, could you tell me how you can upload a custom avatar, like yours for example. Ive been digging around in the settings and cant seem to find such an option?

go to settings. click on edit avatar. then custom avatar, then upload from your computer, keep size low enough to allow upload.

Hmmm the only option im offered are "do not use avatar" & "test"

Ahhhh yes of course silly me using 415

If it’s just for cable calculations then somewhere near will do.
