V.O.E.L.C.B.

It dawned on me fully today while working in an old holiday chalet circa 1940s.


The man in the next chalet was trying to use his old Black and Decker 1970s car boot sourced electric drill outside on the grass. He was making a wooden clothes hanger with wood and pegs. A jolly good job too.


I had had a quick look inside his chalet as he needs some new sockets. The  fuse box is an old cream coloured Wylex 6 way unit with fuse wire carriers. There is an old Crabtree V.O.E.L.C.B. installed before the fuse box.


As he worked in the garden drilling wood, it dawned on me that he had zero shock protection as he would if he had a R.C.C.B. installed.


It's strange how a picture speaks a thousand words.

  • I think 500 mA is realistic as Normcall‍  says, assuming 30 mA would be very foolhardy.


    Time was a bit of an unknown, there isn’t any way to determine how long it took them to clunk off.


    Testing was just applying voltage  to the earthing system with a transformer to see what happened, with the anticipation of a clunk.
