This seems like basic GCSE level physics/electrical theory rather than CPD - I’d be a little concerned if there are “qualified” sparks out there that need to learn this now 😮

I am aware that you have other videos, However I think you would also consider the length of the coductor and it's cross-sectional area . To let you know, will the conductor carry the proposed current adequately or have an abundance , costing the client money.

Great video again. Just one question, though it’s something I come up against a lot… what should the pfc be if at 60A, 80A, 150A, 200A, etc.? I’m sure I’ve been taught it, but forgotten.

Excellent Joe! Can you clear up a 3 phase design please? I'm unsure whether U0 is 400V or 230V and which one you use to multiply it by root3... Right now I think this... You use the nominal Phase Voltage. This will be 230V in a single phase installation, but can be 230V or 400V in 3 phase depending on the supply.. usually you have a star supply from the transformer so U0 is still 230V, but is there industries that use a Delta supply and therefore U0 would be 400V and would you still times 400V by root3? Hopefully my thinking makes some sense. Anyway thank you I love these videos and I've learnt so incredibly fast on my journey to becoming an electrical engineer! Edit. my bad, I got line and phase voltage mixed up. U0 is always 400V and therefore needs multiplying by root 3 if the supply is a star supply. So if its a delta supply, you don't need to multiply U0 by root 3?? Because phase voltage and line voltage are the same????????

Yes on a 3 ph delta load the current will need dividing by root 3. i.e a 15kw load will be about 21A.
