How to work out the power?

[shocksl]

Hey guys

I can pretty much do the rest of the calcs.

But how do I know what the power is ? Once I got it the rest is just following a process.

Thanks.

Read the question….. ALL of the question….

Is it that the data is missing ? So effectively I can put any power in there?

I was thinking p = I 35A x (400 v Square of 3)?
Will that be acceptable?

That question is almost as bad as situations i get with clients, one of the most important info missing, lol
Anyway as for power, this can be expressed as KVA or KW, however key info missing again, so you can only provide KVA.
Try ChatGPT and ask it to calculate KVA based on a load current of 35A and supply voltage of 400V.
That would have been a great question and a good use of BS7671, shame - good luck

Sorry - am I missing something here? To me it seems that everything is there with the exception of a distance?

Unless we assume unity .............
