Current in power distrobution

(OP)
Hi guys,

Fairly new to electronics to you may have to bare with me!

I've recently started working as part of a stage crew where we deal with power on a day to day basic. We run 63 amps through a distro which outputs to 16A, 13A, 15A.....etc

What i cannot seem to get my head around is how the current it distributed

Take this product by Rubber Box http://www.rubberbox.co.uk/on-the-shelf/splitters/...

How can it have an inlet of 16A 240V and two outlets of 16A 240V?
Surely it would have to be 32A 240V inlet to 2 x 16A 240V outlets?

And the same goes for the 63 amp distros that we use that distribute more than 63 amp out

Please unconfuse me!

Thanks in advance
Chris

RE: Current in power distrobution

Just because it's rated for 16 amps does not mean that your going to use it. It's a standard sized connection (so they are all the same), the incoming could be 16 amps, and then one outgoing could pull 2 amps and the other 14. Most likely it would be around 10 amps and 3/7 amps for the outgoing. Equipment tends to be oversized so they don't fail during productions (the actors complain if they catch on fire).

If the panel is 63 Amps three phase, you have 63 Amps on each of three phases

RE: Current in power distrobution

It is actually difficult to follow your thinking. But I think that you mean that the two outputs shall carry rated current, say 16 A, and that you then need to input twice that sum - but that is not allowed.

If that is how you are thinking, then rethink. The total capacity is 16 A. Period. You can load output #1 with 16 A and zero from #2. Or you can use any combination of loads on #1 and #2 as long as the sum doesn't exceed 16 A. Capish?

Ahh right gotcha!

Thanks!

RE: Current in power distrobution

Fine! And welcome to Eng-Tips! Appreciate you using "civilized" writing instead of txt, which is getting on my nerves.

You say 240 V - is that UK? I thought you had 'harmonized' like the rest of Europe? You know, we went from 220 V to 230 V to meet you half-ways. Shouldn't you also go to 230 V, then? Or are you cheating on us? wink
