420 Watt Hedge Trimmer.

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?

Should buy a cordless model

Weight and cost! I have a substantial petrol trimmer for my large hedges - bad move - far too heavy for Mrs P to use! ?

Any road, I thought that it would be useful to get a lighter one for my little box hedges. Sticking with the same make, cordless ones were just as heavy as petrol ones because of the weight of the battery. So at half the weight, it had to be a plugged in one. But it's perfectly safe 'cos it is plugged into an SRCD. ?
