Pulling in swa

Just being nebby but what's it feeding?

Sand , lay cable . More sand , warning tape, back fill trench

job done

forget the ducting , waste of money and time

 

[DefyG]

It is an expensive cable

And the sand wont be cheap! 200m at 200mm thick (100mm below cable and 100mm over the top) and say 200mm wide trench = 8cu m (8 builder bags worth)!

Single socket maybe?

Single socket maybe?

Well 5% drop and 10mm single phase comes to 12.3A over 200m so not far off it!

Doubt it could be that, I just did a quick VD calc and 5% is exceeded at a load of 13A over that distance for 10sqmm

 

[DefyG]

I calculated 7.54v at 13A over 200m but at 12.3A it could be slightly under 5%

Well 5% drop and 10mm single phase comes to 12.3A over 200m so not far off it!

but either way certainly nowhere near 3% for lighting!

~12A is a lot of LED illumination!

Football park?

If pulling a 200m length of duct over a 200m length of SWA with a 200m pull cord you need 400m of space in a straight line to do it, and that is only if the draw cord is already in the duct, I did this with an alarm cable, but only 100m, would be easier in 50m sections with draw pits.
