32A to 16A adaptor (230v & 415v options)

  • Sale
  • Regular price £65.99

Heavy duty adaptor to enable either a 230v (3 pin) or 415v 32A (5 pin 3P+N+E) supply to safely feed a single 230v 16A 1 phase (3 pin) or 415v 3 phase (5 pin 3P+N+E) socket. 

When 16A plugs are connected to a 32A supply, it is absolutely vital that each one is protected by a 16A MCB (circuit breaker). Unless separate 16A MCBs are provided, anything plugged into the 16A sockets is not protected at 16A as it should be; it is protected only by the 32A circuit breaker from the supply. In the case of a fault, the cable and appliance, which are only rated at 16A, could become dangerously hot, causing an electrical fire, without tripping the 32A MCB. 

Unfortunately the use of unprotected adaptors with an MCB is a common problem found on the inspection of temporary installations, mainly due to unscrupulous online suppliers providing them for sale, with no regard to the serious safety impact they present. A picture is provided below to illustrate the dangerous item:
