i was recently working as a temp wiring up xmas decorations and was told not to double up cable ends to terminate them because doubling up increased the csa therefore according to ohms law increases the current. I continue to double up as i've been trained (not at xmas company anymore) as do the lads i work with now, but theyve all conceeded the point when i've mentioned it. just wondered if its valid or just a crafty windup.

Hi
Its a wind up ,"doubling up" makes the conductor longer therefore increses the resistance so the current would be less acording to ohms law,although very neglegable
doubling over fills the terminal and makes a better connection.so you should always do it if you only have one cable

This means "folding" cable over on its self?


Must admit i no longer do it/

I do it.

Good to hear it my friend

Bane

It's only polite to fill the whole hole my friend

wayne

its definitely best practice to fill the hole

cant remember what its like to fill a hole!!, good at simulating one tho. lol

Bane

LOL

What does LOL mean?
