cable sizes!!!!! HELP NEEDED

[dadavid6]

i need to run a 95 meter armoured cable to draw 50 amps, 230 volts, what size cable do i need?

can someone help me please?

A mimimum of 25mm² if you want to comply with the 4% maximum volt drop. (drops about 3.5%) if this is a submain then you'll have to leave some volt drop for final circuits, and 0.5% might be a little tight (though increasing conductor sizes there might work out cheaper than using 35mm² SWA [2.6% drop] instead of 25mm²)

Good answer

so what cable size do you recomend i should use?- if it was 32 amps, what size cable should i use? for also 95 meters

thank you!

95 metres, swa 25mm, love to know how much that would cost

16mm² (which drops 3.7% of supply voltage)

I recently installed 225 meters of 35mm 4 core SWA

Do you have any idea of the weight for the poor installer, never mind the cost.

Answers on a postcard


95m 25mm 3 core SWA I would guess £500 trade.

thank you for all your help

there is an eaiser way - use a forlift or if your really desprate use a 360 digger!!!!!

What are you installing, as there may be a cheaper/easier option.

And I know I'm going to get stick for this Q, as I always do, but it needs to be asked.

dadavid6 - on what basis are you doing this work if you don't know how to work out what you need, or where to look the info up?

now you're just looking to cut corners to reduce cost.
