Derating
Hello all
This is my first post so I shall add a bit about me.
I am a student /apprentice currently working and learning with a company in Randburg. Absolutely loving it. A medium to late career change after Covid initial lockdown when I relaized running the family print business was just not cutting my mustard anymore.
I am also currently registered to write my P1 and P2 in April.
Now to my question.
We are having a sort of chat about running a new 3phase 4 wire cable vs. Joining it. (Basically the two 3phase sockets being moved.)
I would like to find out if there is a derating factor of sorts that can be used for when the cable is ferruled and joined in a junction box ?
Each cable run is approx 60meters.
Many thanks !
Dyl
