Me and Joe look at a modern 400 volt cable joint to 230 volts supply for a TN-C-S (TN C S) Earthing system. We see how in new cable joints it's almost impossible to lose the combined neutral and Earth connection. We see the Aluminium line conductor and how it is connected within the joint as well as two different ways the combined neutral and Earth conductor can be connected. The broken PEN conductor (PEN - Protective Earth Neutral) it currently a hot topic in the electrical industry with older joints failing across the UK.
See what’s going on inside a cable joint.
