extending cable

[mike75]

i am moving a socket down the wall and i have bought 5mm wire to do this. When i have opened the original cover the wire is 3mm. Am I ok to join these two together?

 

[fireman22]

if the cable is larger than the original it should be ok, more info or pics would help tho

 

[mike75]

basically, is it ok to join 5mm wire to 3mm wire

 

[fireman22]

basically, yes.

Thanks for reply.

Just another question, what about joining 2.5mm to 3mm?

Where are you getting 3mm and 5mm from?

 

[michaelcouper]

buy some 2.5mm Twin and earth and do it right.

dont use two different sizes of cable, yes it will hold the load, but u might have loose connections.

dont know where your getting 5mm cable???

 

[mike75]

the existing wire is 3mm and i have bought 2 new ones 5mm and 2.5 mm

How are you measuring that, and who is advertising 5mm cable for sale?

thats fine, i re-read your post i think you've measured 3mm instead of 2.5mm


that is fine. only take your new cable off existing socket if there are two cables there already. thats me assumming its a ring main!

 

[mike75]

i shall disregard the 5mm.

I know it is 2.5mm as i have bought it new.

As for the 3mm cable it is slightly bigger than the 2.5mm and when measured the cross diameter is 3mm.

Will the 2.5mm be ok joined with the 3mm

 

[michaelcouper]

no, just buy some 2.5 Twin and earth from wickes.

 

[michaelcouper]

you dont get 3mm, its either 4mm or 2.5mm

you dont get 3mm, its either 4mm or 2.5mm

Unless he means old 7/0.029 which is near as damn it 3mm
