GARRY WENT: I FOUND THIS THREE-PHASE SOCKET WHILST CARRYING OUT AN ELECTRICAL TEST ON A BIG COMMERCIAL UNIT.
Another Unsatisfactory finding in commercial environments, a potentially dangerous socket-outlet, especially as the design load is likely to be high, with no cpc.
We can see the manufacturer has given the facility to terminate a cpc – it just hasn’t been used.
Supplying the socket-outlet, we can see an armoured cable (SWA), but there appears to be no earthing washer to allow an earth tail to be extended to the socket-outlet.
We will need to see if the armour has a connection to the MET at the point of origin of the circuit.
Given the SWA identification colours, we can almost date this circuit to roughly a pre-2005 installation, which is when we started to see the new cable colours take effect.
