Hi Guys,
Could some one please confirm the following just in case i made some stupid error before I spend £200 on cable!
Cable required for workshop at end of garden. I worked out the max power use in the garage would be 8kw (air compressor 2.2KW, heater, power tools, lights etc) I can't see this ever happening all at once, it would be more likely 3-4kw on a regular basis.
SWA 10mm
Load 8kw
Length 50metres
Voltage drop 6.6v
% drop 2.9%
Current Load 34.78 amps
Max cable load 44.5 amp
No point in using 16mm as 10mm covers everything and more?
The mcb at the house end should be 40amp just below max load of cable?
Thanks
