How to wire a South African three pin plug top Remember blue = left (bLue) and brown = right (bRown) Blue- neutral Brown= live Black = neutral Red= live Yellow/green= earth
Allway loop the ends fr better strenght and avoides cutting the strands ...earth cable should be as long as possible, if the wires get pulled out it must be the last cable too come out...your protection from electrocution....tightthe screws... wait a few secs for wires too compress..then they can be tighten again for a proper secure connection.
I got a light fitting with no earth wire (just 2 wires, blue and brown) ... I need to add lead extension, switch and plug ... is it safe to use such an item without an earth while obviously making sure they're insulated etc?
No the BLUE in N - Neutral. L is the Live wire bringing power to the appliance. So if you attached the Green to Earth and the Blue to N , whatever wire you have left goes into the L - LIVE.
The neutral is grounded so it is at the ground potential. The live or the line has potential to the ground. It works even if they are reversed but things like lamps are safer when they are correctly. The switch will cut the line and there will be no voltage on after the switch when it is off.
