    EICR bonding connection not visible/accessible

    What is the case in if you carry out an EICR and you cannot get to the connections of gas/water bonding to get a reading? The gas meter is outside but I see no bond to it. I cannot find the water stop cock. There are a few GY cables at the MET and I guess I could disconnect the cables and long...

    Main Bonding with a crimped lug fixing!

    Hey All, At college, I was taught that main bonding - such as bonding to a gas pipe - must be carried out using a continuous copper conductor running directly from the Main Earthing Terminal (MET) to the pipework, with no extensions or alterations permitted. If the bonding cable is damaged or...

    Clear up a bonding debate of ours.

    Hi all Wondered if you could clear up a debate we are having at work. Gas inspection has said no bonding to the gas meter or pipe in block of flats. One engineer says it should be run to the meter. One says it should be installed outside within 600mm of where it enters the building on the blue...

    Bonding gas and water

    Hi, so I’m on a job currently and there’s no bonding to gas or water! Gas isn’t an issue, as the meter is in the same cupboard and the consumer unit. Water stop tap is on the complete opposite side of the house with no easy route without a fair amount of damage to decoration. Routing the...

    UK Gas Bonding Certification

    New gas boiler install. Previously no gas in dwelling, water is plastic. So no bonding presently. No other work, boiler supply to use existing Electric Heater Circuit. What certification should be used, It's not a new circuit, so not EIC. So just Minor Works?

    UK Scenario where lack of supplementary bonding is dangerous

    So I know why it is done, where it is done and how it’s done, but I’m yet to see a scenario where there is shock danger in a typical bathroom in a dwelling provided a) the main bonding is in place and b) the CPC’s of all circuits are connected together in the CU (as they will be). Consensus is...

    The wisdom of equipotential bonding

    I'm probably displaying my ignorance here, but fortunately I'm not one of those people who can't stand to be laughed at! I've been thinking a bit about one of those things I've tended not to dwell on. The technical reason for equipotential bonding is obvious - if you create equipotential zones...
