low voltage electricity to shed

[miger]

Hi All!
I'd like your thoughts on this idea please:
Can i run the power off a plug in 12 volt AC transformer, that was powering my garden lights, to a garden shed 30 metres away and at that end attach one of those triple car lighter adapters and run things off that?
I think it sounds ok, but i thought i'd check first
i'm thinking of this because running 240v up the garden in any way is not an option.
cheers

wont work.

get several quotes to get mains there

Thanks for the reply Breezer!
can you elaborate on why?
thanks

i was going to at the time but thought better of it.

still, as you ask.

too much voltage drop
(unless you run a large cable to overcome this which i doubt you would)
what are you going to run? 1 fairy light?
Becuse thats about as much as you will be able
you cant use any mains kit,
waste of time
your power supply will be too small
lots of other things too

Thanks for the explanation-----i appreciate it

Why not?

Purely cost at the moment i'm afraid
anyone any other ideas?
( if there are any!)
thanks

low voltage electricity to shed

Firstly, what you proposed to supply the shed with wasn't low voltage it was extra-low voltage.

The IEC definitions of voltage bands are:

• Extra Low Voltage: AC below 50V and DC below 120V
• Low Voltage: 50 - 1000V AC or 120 - 1500V DC
• Medium voltage: 1kV - 35kV
• High voltage: 35kV - 230kV
• Extra-high voltage: >230kV

This is not some pedantic technical point - if you start getting involved in doing your own electrical work, and start learning about regulations etc you'll come across references to "Low voltage", and it'll be no good you thinking that that means 12V...

Purely cost at the moment i'm afraid

Secondly ELV will be much more expensive because the cable you will need will be about 4.5x thicker for any given load.

The cost to dig the trench will be the same, but the cable will be 4-5x the price.

Extension cable and an RCD will see you ok until you can afford to get it done properly.
Unless you are welding of course

nothing so permanent as a temporay job
