Protector-Plug Flymo

2. SWITCH ON. But can't find a switch, the light does flash, but 4. PLUG IN APPLIANCE. And the appliance is not powered, and the light continues to flash, I was going to test it, but one it is 30 mA so have no socket over 30 mA to test it with, two batteries flat in the tester, and three can't get it to turn on, so seems going in the bin.

Found when clearly out some old tools etc, and at first glance thought it was 10 mA, since 1990s all my sockets have been RCD protected, my dad it seems unlikely he would have used one, so likely father-in-law, the pin protector still on it, but seems it has seen some use.

Think I may have found it. Noted shutters open, sharp rap closed them, but still no power from it. Google takes me to Wellco RCD which is very different, temped to break it open to see if a switch on the shutters.

Curiosity got better of me, so broke it open

there are contacts worked by the shutters, also seems at some point water got inside.

Hiya Eric = no sign of a test button?

What I might have been tempted to have tried is the old tried and tested "Bang Bang 240 Test" as we used to call it .
a 8200 ohm resistor of highest wattage to hand wired across L & E pins of a spare plugtop including a 1A fuse as a Go/No Go test.

Theoretically 240v/ 8200ohm = 29.27mA or 230v/8200 = 28.05mA might give an indication that approching 30mA likely to trip.

Usual Caveats apply of course.

It did seem that the shutters may have also manually worked the relay, hard to work out now it has been broken open.

Does this help

?

I helped a neighbour with one some years ago. I can't remember any detail now but it did go in the bin.

I had another type with a start button on the back which had to be pressed after powered but could only be reached when plugged into a reduced size extension socket which somewhat defeated the objective.

I remember one of those from the 1980s. I think it may have been one of the first mass-market affordable RCDs / ELCBs.

I have no intension of reassembling it. The white bits seem to also push on the top of relay as well as the contacts, and I am not sure how they interconnect with each other.

I can't test it as all sockets are RCD protected so likely the main ones would trip first.
