    ring main socket wiring causing mains to trip

    shock from water pipe

    Thanks for that. Apparently its a TT system but the rcd doesn't trip. From what you say then it is a circuit fault AND rcd, as if pipework is providing fault path the rcd should detect this. If I was to put a voltmeter on pipework and to earth stake and say got 60v. By then isolating each...

    shock from water pipe

    Asked by friend at work for some help which is an area I don't get involved with much as a maintenance engineer with little domestic experience. He has moved a washing machine into new position and whilst leaning on it, he touched the water pipe and got a small shock. Didn't think much of it...

    bonding help

    Those regs are before my time, I can only assume that a kitchen is not classed as a special location. However having said that, my mains water incomer is directly under the sink and the taps are connected to the sink. So they are at earth potential. For instances where the water incomer is not...

    bonding help

    Bonding is required where there is a possibility of simultaneous contact between extraneous conductive parts and exposed conductive parts. It is required in a bathroom as it is a special location. BAS are you on line and can answer this before I go to bed please. Many thanks

    bonding help

    Ericmark, when I said on the QT, I meant as a favour to a friend with no invoice from my firm. Certificates will be issued and traceable to me with my name and address on, using Megger Powersuite Professional. Meter has a valid calibration certificate aswell. Last calibrated in Nov 08 when I...

    PAT testing query

    Thanks for the replies. Why is it then that the Code of Practise puts these maximum lengths for extension leads in it? I can see that the ELI for sockets would be well under for some circuits, thanks for that. We do not have ant rcd protected sockets at work so I am right in insisting on rcd as...

    PAT testing query

    Hope you can settle this arguement. Boss came into work today with qty 4, 30m extension leads all on a standard plug. I told him they need PAT testing before use and as they are over 15m's for 1.5mm cable they need the plugs cutting off and replacing with rcd plugs. **** off he said, if they...
