Max length

[scott 123]

Need power to shed .thinking of a spur from 32a ring as only want 1double socket and light
is there a max length for a this

The max length will be what your calculations say it is.

What he said^^^^^^^^^^^^^^^^^^^^^^^^^^^ cant believe you have asked that question, you are an electrician aren't you?

Max length eh ? I'm sure he was in a 70's video I once saw ........

No that was max headroom

 

[Andy78]

Nah not the video I saw. "Max length in peril in VD land"

It must have been an electrical reference video. VD must stand for volt drop.

So whoever it was had an STD

It's gone from cables to phones.

Well it is contagious, or it was when I was a lad

Lol passed down the line.:smile5:

This is going to be interesting...

Hi Scott. The best thing you can do is show us your calculations and then we can give you advice.

 

[Marvo]

There's nowhere near enough info in your question to do anything with but a lot of guesswork. According to the info in your profile you should be able to do the basic load and voltdrop calcs and you should be familiar with the regs so.....you're gonna have to do some calcs and come up with a circuit design.

 

[D Skelton]

According to his profile... I doubt it.

Poorly worded question.. Is max length purely down to volt drop or is there a max permitted length from a spur

 

[Spoon]

There is a lot more to calculating the max length of a cable than just VD. Google it and find out.

too ah, too long and he'll get his feet wet in the irisn sea

What do you think? If unsure check the BGB or BYB and come back with any questions which you need to clarifying. We will help you but you need to at least show is your thoughts and ideas.

Scott, just calculate it and show us your thoughts, its quite a straight forward process.

What is the R1 + R2 value and Zs at the point where you want to spur off?
