    Type of earthing to sub-board

    Hi securespark, You said:- If a property has more than one mains water feed that comes into the property independently of each other, then each should be MEB'd back to the MET. Thats strange as the local supply company inspector told me earthing one water main was adequate as long as both had...

    Type of earthing to sub-board

    I am getting some what confused now. The room is a utility room. I currently have a water main rising in one corner to which I am going to connect dishwasher, sink unit and tumble dryer - I could use PVC pipe work although I don't like it. On the other wall I have a gas boiler (elec...

    Type of earthing to sub-board

    I was told by a electrician who works for the local electrical supply company that as all the copper pipe work to the gas central heating/radiators and sink units/baths etc was bonded together within the house including the extension and it was all within the same building one earth wire back to...

    I omitted to say that the SWA cable to the shed is in a PVC box and the gland has a PVC sheath over the gland - no connection between the gland and the shed electrical installation. The thirs core in the SWA cable is terminated in a connector and also NOT collected to anything within the shed.

    Hi Spark123, The extension is in the same zone as the house and the extension has its own water mains (two incomers). As the hot water system and heating is all copper I have bonded the pipes throughout with one 25mm earth bond to the earth terminal at the meter position. The gas meter is...

    Hi Spark123, I think may have confused matters a little since my first posting. I have two types of buildings - Extension and Shed EXTENSION: I have an extension ON the existing building with a 3 core SWA cable, the third core (earth) will be connected with the armouring at both ends one to...

    Thanks JohnD & Crafty1289, John's reply must have crossed with mine. I will fit the RCD (already have) in the extension room, as you say it will be easier to reset in any fault conditions. I think you have all answered all my questions - Many thanks for such a quick responce. Regards

    Type of earthing to sub-board

    Hi Crafty1289, Thanks you are correct regarding the shed type building. I have an SWA cable to the shed and in this case I earthed the SWA armour at the house end only. The armouring in the shed is NOT connected to the earthing within the shed at all. I have no connection from the earth...

    Type of earthing to sub-board

    I am a retired electrician and I have build a new extension to my house (brick building) and as this will contain several electrical items (washing machine/dishwasher/tumble dryer etc) I have run a new 3 core 10mm SWA cable from the mains position at the front of the house to this new room at...
