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. :confused::confused:

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/

(A bit crap I know)
Dont you agree with my answer then ,im not sure if im right either .if the cable is doubled over ,the actual cable is longer,the aditional length is in series with the other bit,therefore resistance must be incressed ,the csa is also incresed at that point so the resistance would be less ,bit of a courundrum ,wheres the welsh wizard gone?:rolleyes:
