420 Watt Hedge Trimmer.

Zoomup
The owner of the 420 Watt hedge trimmer decided to redesign the 0.75mm2 two core flex by cutting through it. This caused a dead short. His house is supplied by a TN-C-S supply. It has a consumer unit in the house with a B16 M.C.B. dedicated to supply his garage. The house consumer unit is a split load type with 30mA R.C.D.s. The hedge trimmer had a 13 amp plug fuse fitted. It was supplied via an extension lead fused at 5 Amps.


In the garage, where the hedge trimmer was plugged in,  there is a two way garage unit with a B16 M.C.B. for the sockets and a 30 mA R.C.D.


When the hedge trimmer flex was cut through which protective device(s) tripped off or ruptured?

    I had a similar call out, an elderly lady said the power supply to the freezer in her garage had failed and all the food had defrosted. The 30 amp fuse in the garage board has mysteriously blown, however when quizzed she pulled the hedge cutter out from under a bench with multiple taped repairs in its flex and enquired if it could have been the cause of the problem.
