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.

  • Don't trust the tester to push out 200 mA.  Measure it with another meter in series [as well as the VOELCB coil].  Or connect the coil to a car battery.   The tester should test with e.g. 200 mA to a near-zero resistance, such as a conductor through an RCD.  But if the VOELCB's coil really is tens or more of ohms of resistance, your tester is unlikely to produce the required voltage to get 200 mA [or 35 mA] - it probably only runs off a few AA batteries.


    (You see ... I really don't want to give up my faith in the reliability of the old stuff, until forced.)
