    Rcd not resetting.

    Disconnect neutrals in the shed board , switch off all breakers & try again . Reconnect one by one which may indicate the fault . It could have failed when you switched it off ...bit of a coincidence but strange things happen with electrics . Is it damp in there??

    Rcd not resetting.

    Thanks guys. Electric was working ( lights) right up until I turned the power off. I've tried all positions - pushing fully down from halfway then back up, but it won't stay there. Can't see that it could be a wiring fault as nothing changed other than removing spur from first socket, so should be less complicated. So I don't need power to reset the RCD, right? Kopp 40 0 03

    Single Phase motor wiring question

    I also can't think of a good reason to have a bench grinder run backwards. Apart from anything else it would direct the detritus into your face rather than down the guard . Presumably you are electrically knowledgeable enough to know the importance of checking the insulation of this old machine. With a machine of that power and age there could be a centrifugal start switch. I would be inclined to be dismantling it to establish just what I'm dealing with.

    Wylex rcd button not working

    check PSCC/ PFC - look for faulty incoming neutral, anything weird is usually a neutral!

    Single Phase motor wiring question

    I will get some readings tomorrow from the motor windings As I mentioned on my first post, I am not confident having two directions on my bench grinder without some sort of a safety device. On a side note, Tormek market their grinders turning clockwise.

    Rcd not resetting.

    What make of RCD is it? and how long has it been operating properly for?
  11. You more than likely have a wiring fault. You need to check all the wiring on the circuit to ensure you have no short circuits/incorrect polarity etc. As this is a shed it should be fairly simple to fault find.

    Wylex rcd button not working

    I would suggest you disconnect ALL the neutrals from the relevant neutral bars, turn off all the MCB's, and test the RCD properly with your MFT IME RCD's rarely fail in service, especially after such a short period of time N-E fault likely PS - RCBO boards are far better...

    Wylex rcd button not working

    neutral in the wrong bar or N-E fault
  15. Wylex split load board, installed 2 weeks ago Field called me on a Sunday afternoon saying 1 side tripped and now he's resett it but test button dosn't work. So I grab a spare rcd a few tools the wife and kids as they very mad about helping a good friend. Test rcd button and times. Button dosn't work and 1x above 310ms. So swap rcd to another and same results. When you plug something in on socket circuit it trips rcd now, he says wasn't before. Insulation at 250v live neutral + e above 200 My wife going mental so agree with mate I'll go back on Monday Coincidence both rcd faulty or am I missing something. Am I been thick over looking something simple

    Rcd not resetting.

    Have you tried tunring the RCD fully off? some trip to a half way position and wont switch back on from there. Failing that, you have a fault, either with the wiring or the RCD

    Two-way wiring

    simple - run a neutral alongside the strappers. youd still need the same number of cores as you proposed, just instead of linking commons, the 3rd core is the neutral (well, 4 core, since youll need a cpc) what tranining / qualifications do you have?
  18. Evening all i have a shed which has a power feed into a small consumer unit with two MCBs and one RCD. I needed to disconnect the sockets leaving the first socket in place so flicked the MCBs and " inadvertently" the RCD also. I disconnected the sockets that were fed as a spur off the first, leaving the first in place, and connected back up. Now the RCD will not reset i.e return to top position, leaving no power to lights or socket. I have turned all the power off and it will still not reset. I tried putting all the sockets back on I.e. same as original but still no joy. Is this a faulty RCD or am I missing something here? Does a RCD need power to reset i.e. Could the problem be back at source from the main consumer unit? Any thoughts gratefully received. Cheers

    And I should have said - yes, 20mm round conduit, through boxes at each light, 1.5mm 6491X cable, earth to every point.

    Two-way wiring

    Thanks all for the prompt responses, and yes (Geoff and Andy) I can see the potentially fatal error of my ways in having one or other of the wires at the lights always live - so I'll not do it that way ! Murdoch - I cannot find a wiring guide which does not take the supply to the lamp (/ceiling rose) first. Deke - thanks, that looks good. Is there any way of embedding a schematic or image into a forum post to check my understanding ?

    Two-way wiring

    OP - you are over complicating matters ....... just following wiring guides readily available .......... and don't go light to light with the 2 way switching and strappers ... these only need to go switch to switch

    Two-way wiring

    so as above, switching neutrals. whilst it may work and function, its wrong and potentially dangerous in that it can be 'off' yet still live enough to kill you

    Two-way wiring

    Hi Barney, If I've understood your wiring description correctly it's a definite NO_NO! I think you are suggesting putting the two strappers between the switches onto the supply with the lamps connected between the two switch commons. Is that what you mean? If so, don't do it. When the lamps are OFF, it's because both lamp terminals are on neutral OR both on live. In the latter condition it's potentially lethal to a lamp changer.

    Welcome Mecheng , your name suggests you are a Mechanical Engineer ...or ...a builder of Neolithic Earthworks ?

    Single Phase motor wiring question

    On a H&Safety issue , you don't need a bench grinder that turns either way , its an accident waiting to happen . In my experience they spin down towards the tool rest or bench , spinning the other way could throw a piece of work up, unexpectedly at the operator.
