cable size help needed please

16mm 3 core as a suggestion.

Assuming a 240V supply, unless all loads within the stables are specifically designed to work at lower voltages (which I very much doubt) the Ib would have to be less than 8.5A to allow a 16mm SWA to provide enough voltage to allow the lighting circuit within the stable to comply with section 525. I would think that with the heaters, the socket circuit and lighting needed this is going to be highly unachievable! Think bigger

Skelton I cant believe you took the bate with that silly answer lol

 

[D Skelton]

Maybe so, but I just read it as it wss.. Which was a suggestion.

 

[Simlec]

I don't think Mr Sajeel's 16mm is a suggestion, I think he thinks its right

 

[D Skelton]

As do I, and I was politely 'suggesting' that he thinks a little bigger! Lol

I did mention a suggestion as I.e. also said calculate loads don't care what you think

As I said would need calcs of load to work out voltage drop so a correct cable size can be determined I agree bigger due to length of wiring

 

[D Skelton]

Even without calcs I could safely say that Sintra hit the nail on the head with a minimum cable size of 70mm, I would say even with diversity applied. It's very much the rating of the heaters in this situation that will determine whether or not a 95mm cable size would be needed.

250 metres of 70mm.... Thats going to be one expensive heater. 5 grand..?!:devilish:

Wouldn't it be cheaper to buy the horse a jumper and a torch?

No one has mentiond the volt drop here as a 250m run will incur a significent volt drop!

Post 14 and 16 make reference to volt drop

 

[Octopus]

Me thinks the OP has done a runner.

 

[Guest111]

In the worst case scenario,54A means a very big cable with 3% volt drop this could be a 120mm so start doing all the calcs.www.[B]doncastercables.com[/B]/technical/cable_calculator

I would think that once the OP has done the calcs, the estimate he submits will be thrown in the bin far quicker than the time it has taken me to write this reply......
