Measuring the Continuity (Resistance in Ohms) of the Protective Bonding Conductor to Water and Gas

Students training aid for testing continuity of the protective bonding conductor. This is the conductor that connects to the intake point consumers side of the metal gas pipe, metal water pipe and metal oil pipe in an electrical installation. The supply needs isolating and parallel earth paths removing in order to do this dead test. The maximum value for the continuity of the protective bonding conductor is 0.05 Ohms.

    I looked at a consumer unit swap recently. The MPB for the gas is there at the board but a new meter has been recently fitted and the bonding conductor is missing. I've disconnected the cable at the MET and done a continuity test on the copper pipe and I get an acceptable reading but I obviously can neither see the cable or the safety label. Is my only option to run a new cable.

  • @hond654
    @hond6543 жыл бұрын

    Maybe somebody already asked: leaving the other main bonding in the MET you might distort the measurement of the individual connections by leaving parallel resistence in the circuit? I saw one comment the IEE GN3 states that 'the leads of the instrument are connected to each end of the conductor...One end...may need to be disconnected to avoid parallel paths' 2.7.5 Test method 2 para. 3. "may need" is a bit vague there?

    Hi Gary, enjoying your videos, I have recently been told that coiled/springing your earth cables (as seen in this video) is not best practice as it can create inductance in the circuit and could give poor earth fault path readings, I am sceptical, have you any thoughts on this?

  • @GSHElectrical

    Can I ask a question please, this is not in the UK so you may not want to answer....I am Australian living in Philippines, but could apply to many places, the water pipes here are plastic, there is no gas or whatever...you have a earth stake in the ground and one at pole, plus the earth (CPC) is linked to neutral in Cu. The house's are usually concrete and of course full of steel reinforcement, sometimes the use the steel reinforcement as the bonding or the earth itself (no earth stake), what are your thoughts on this...I should point out the the steel reinforcement does enter the soil, but of course embedded in the concrete..

    Hi. Thanks for the question I think.... plastic pipes do not need earthing, it sounds like your using a version of TN-C-S and TT UK earthing arrangements... foundation earthing is having its profit raised in the UK when the 18th edition comes out as an additional earth.

    Why wouldn't you do a Ze & Zs test at the same time? I dont understand why Ze & Zs is a live test when you have to turn off the power and test it dead. Why is it a live test? & why cant you do it in the dead test section after insulation resistance?

    The maximum resistance allowed is 0.05 ohms. There’s a question in the past paper that talks about testing continuity of main protective bonding conductor to a gas pipe which is 10 mm and 43 meters long. The expected reading in 0.08 ohms which is worked out through calculation. Is this then not allowed or why is the maximum allowed 0.05? Anyone able to help?
