I was always taught never to trim RCBO leads. I noticed on another thread the other day/earlier on that someone said they did. What’s the general consensus on the subject? The reasons explained to me as to why we shouldn’t cut them were the RCBO was calibrated with that length of cable on so it shouldn’t be changed (I suspect this is a load of crap) and because it’s flexible cable and terminated with a ferrule or tinned it shouldnt be cut because it would make the connection worse. To this day I’ve never chopped one RCBO lead. I just usually loose the extra length neatly inside the enclosure. Obviously if the Manufacturers instructions say don’t cut then we shouldnt be cutting them, end of. Thoughts?
