Shed power

[Klj1234]

Hi guys am new to this forum

Can someone give me advice on shed power

I am looking at running power supply to a shed which will have a small chest freezer and few sockets for dewalt battery charger I was going to run 2.5mm swa cable straight form house cu (which is rcd protected)
The shed is approximately 40m away

10mm does seem like overkill. 6.0mm willl handle 45A, VD permitting.

It's the run of 40m with bends and turns I calculate for 50m just incase

so at 40A on 6mm at 50m you VD would be (7.8 x 40 x 50) = 15600mV or 15.6V. but will you need 40A (cannabis farm?)?

30A would be 11.7V - .sensible if you have LED lighting.

As stated its is for a a small chest freezer and the odd charger for drills ect
1 outdoor light and 1 batten style light I have answered the questions over and over

The 40A I measured up for was for over estimate in case later years I need anything else

I can not give any more information than what I already have

please only reply If its related not childish comments like above statement

wonder what is childish about doing a volt drop calc.for you. also wonder if Amazon sell a sense of humour.

Cannabis farm I was referring to bud

There's a joke in there but I'll leave it I think based on recent posts in the thread

And I think Tel doing the calculations deserves a thanks personally.

Cannabis farm in a shed would be easy to find by local plod and a heat sensitive camera.
Same goes for normally cold roof space.

I think we were all a little surprised that you jumped 3 cable sizes after your first thoughts.

TBH, 2.5mm will probably be fine if it’s just a freezer, chargers and a couple of lights ONLY. Nothing else.

It was just the long run i was worried about with the 2.5mm

As for the cable jump

the original idea was a radial circuit coming form my CU in the house plus I totally different radial for hot tub so two different circuits both in 2.5mm
( I haven't done cals for hot tub yet)

Or

The cable jump (10mm) was to power a brand new CU in shed its self then form that board ( shed ) I would power the hot tub heat and shed

Thank you kevin
