150m Cable run outside to spur?

[Connor2425]

Right. one piece of cable from a board to a spur 150m away, the spur is to feed a 12 v power supply. the cable is a straight run externally clipped to a wall. any other info you are looking for you may need to ask me.

What voltage are you exporting... i.e. is it been transformed at load from mains or are you thinking 12v from source to load?
What are the installation methods?
What is the load and characteristics?
and out of curiosity what is the load?

 

[Connor2425]

3 x 12v 1.5amp PSU's

Okay my advice is CALL A LOCAL ELECTRICIAN, because you aren't wanting to give any info to us to help you.
What is the expected load
How is the cable to be installed
Is it 230 or 12 volt you are trying to get outside
Is the whole 250 meter run external or internal


That's better.

At which end is the 12 volt needed?

At the end of the 150 meter run? Or will the cable be carrying 12 for 150 meters?

What type of cable are you looking at using?

 

[Connor2425]

********

should I do a drawing?

one end the board-----150m (clipped to a wall externally!!)------other end the spur<<<12 v power supply

I need to have the 240v closer to where I need the 12v as obviously i cant run 12v over that distance

Right we are getting there, slowly and with offensive responses.

Now, what are the power ratings of the transformers at 230 volt? What sort of cable are you looking at using?

Dillb thats the 3rd time ive posted whats happening

And the 4 time you haven't answered all the questions asked.

I'm ooot

PSU's are 12v 1.5a DC

This is an external wiring install and off the cuff i will suggest you need to run it at 230v until load then transform it down.. as you are running mains outdoors you really need to get a local sparks to assess the situe and advice onsite their are too many questions here and everytime you answer you just leave us asking more questions... you can't export 12v over that length in realistic terms... you haven't really given us a fraction of the info relating to cable calcs and thus suggests you are out of your depth... this install could seem a simple request but can have many requirements to ensure it is safe even after cable selection even the characteristics of the incoming supply could change the way this install is done depending on where/how you terminate you 230v.

Note the time lag in me writing this post and you supplying some further info in case you have already answered what i ask.... ?

If you list your location I'm sure there will be a member who is close to you who could come round and inspect and quote for carrying out the work

lol wow, just wow. I give up. do you even read the previous posts?

This will be done by my electrician who is well in depth, I was just interested in the cable size so i could price it up.

Like I said forget it, Ill have a ring round.

Ahh a DIY question, makes sense now.

 

[Connor2425]

Oh so you read that one Dillb?

Far from DIY, a simple question that im sure someone will advise on.

I just seem to be asked the same question over and over?
