Circuit design

[StuartMaxwell]

Installing heaters in a milking parlour and he wants them to operate on a time clock? 5 heaters at 2000 watts each. Approx 15m run. Current running through will be around 25 amps. What cable will I use and breaker? Only a single phase board. I was thinking 4mm or 6mm radial on a 32amp mcb. Or will 2.5 be suffice?

 

[HandySparks]

How do you calculate your current as 25 amps, given 5 heaters at 2000 watts each? What voltage are you using?

 

[StuartMaxwell]

230 didn't spend much time calculating just rough correct me if so

 

[ArseyDee]

"....rough...."

You're miles out!

Is this an exam question?

 

[StuartMaxwell]

What is it then? No?

 

[ArseyDee]

I'm thinking this is a wind up.....

Judging by his posts on one other thread I'd say this fella is doing everything in his power to gain a reputation as a parasite.

Stuart, you don't have a God given right to the fuel in your boss' van, neither do you have the right to complain about his 'b0ll0cking' for spending his money without permission, the same as you don't have a God given right for someone on here to provide you with electrical design consultation services for free, nor a right to ask blunt and rude questions when someone calls you out for not doing your own research.

Integrity, effort and hard work appear to be alien concepts to you.

**** off

 

[D Skelton]

**** off

As I thought...

 

[killy bing]

you're asking questions that you should be competent to answer yourself?
if not then you should be asking how to work it out, not asking for the answer itself.

rule one of the forums is be nice.... especially with trusted advisor's !!!

i'll pop off and say hello in the new members area now !!!

Just another electrical trainee me thinks, that hasn't got a clue, ...and it seems working outside of the domestic sector too boot!!

9 x 5 =25. i see the Electrical Trainee maths is bang on. NOT!.

Im so gobsmacked I thought I had missed something or was being completely stupid, But no, I would normally give the OP the benefit of the doubt but it must be a wind up.

Weren't too sure about how to include a timer into the installation either, going by the question mark. That would have been the Next question!! lol!!

Ditto.

And after reading post #3, I felt sure I was having my chain yanked!

Shame you banned the fella, there was far more mileage to be had out of him first!
