Yep, i`ll not disagree with that John, in essence. What I was attempting was , what is the best (easiest) way to refer to them in comparison, loosley we calls the current operated (RCD like, comparing currents) or voltage operated (comparing voltages) as a ready distinguishable different kind of...

Could we say that effective it is a rough attempt to compare two voltages 1/ being near true earth local to the installation and the other is the earth at the consumers earth bar, these will always be at different potentials wherever you go on this planet of ours but if we reckon it does not...

That’s good image on phone and WiFi o

Oohhh a bit ruf?

Thanks Flameport

Lidl not Aldi - Parkside Inspection Camera PK1 2.8 B2 IAN 385152_2107 . if that helps

Eric - I suspect that you have a sense of humour kiddo. i think they get sacked and heavily fined if they are caught ever telling the truth, a repeat offence is treason therefore a hanging offence ;)

Hmm not sure. I got one a few years back it was one of those "when its gone its gone!" things from Aldi and I got it for one specific job at the time, thinking it might be useful another two or three times in my working life, Unfortunately I sort of started windin down to retirement not long...

Yes perhaps but you can envisage why they were termed Curren or Voltage operated due to the way they effectively (almost) could be caused via either voltage or current differences although the coil actually operated via current in the coil so I reckon it is fair if not strictly true otherwise...

Blimey - Either a con man or totally thick!

Just to add, you still need to avoid splashes of water getting into the fan heater itself but that is almost always taken care of by the design of the fan heater itself and the vanity unit. In other words if you were just adding a bog standard fan heater itself you`d have to ensure you mount it...

With a slightly better endoscope/boroscope type thingy (you can get them quite cheap if it`s worthwhile) you might be able to better determine exactly what is what). Those of us who are old enough did not have such things, not even something resembling a dental mirror until quite later on just...

I suppose that those of you with long fingernails would not find it impossible to remove push in types in all cases. so a C3 might be justified. My preference would be a spare MCB/RCBO as a usual option

Well finding the joint would be the first priority, then doing L to L then N to N then E to E (example you might find that SWA is E to E on Both so continuiy righ thru or you might not - are both the third conductor and the armour connected together anywhere. Therefore disconnect both ends...

If the ceiling is plasterboard and space allows then if it feaseable to cut in for a dry lining box (perhaps a circular one and put the wagos in before popping the luminaire back in place)? Keeps it in a back box that is only exposed once the light fitting is removed

Agreed John, however there are those (including some very technical engineers who insisted it should have a test before deliberately freeing the switch whether by test button or manually) who insist it should be failed and replaced. Myself I prefer to test then test again and see what shows - I...

I`ll go along with that, but I would prefer everyone to press test every 3 months or so, but they never do! In my mind the "Stiction" is the most important as failures are usually failure to trp within parameters rather than failure to trip at all (although sometimes they do fail completely) and...

Yes - the "ordinary person" those without RCD testers etc have no way of knowing if an RCD is working to any extent. A simple test button performs a simple function, it tests that the RCD will trip (or not trip) under some condition. It will not tell us if it trips within the correct time or at...

Yes John, in essence, that`s pretty much what I was intending to say but you have put it far more eloquently than I.

It would be nice to know how you acheived it and how advice on here might have helped
