    UK Bonding water pipes

    There may be lots of metalwork located outside that is "in contact with the ground" but that would not necessarily mean it requires bonding to the MET.(electric gates ,oil burners ,lighting lanterns etc, etc). Generally speaking their connection to earth is of a very high resistance and...

    Washing Machine in Bathroom

    Agreed.In every home I have lived in ,the most important piece of furniture (for me ,not the wife) has been a wood burning stove.For the simple reason that its the only form of heat that I truly enjoy. However ,during storm "Eowyn" ,we lost electricty for a while . I discovered that my wood...

    Are Quinetic still regarded as the best kinetic switches?

    I did look at them at one point.I don,t believe though that they do any grid switches that would harminize with a traditional switch ?? .At least none showed when I viewed their website. In any case I find it very reassuring that so many posters on here have found the established brands to be so...

    Are Quinetic still regarded as the best kinetic switches?

    Wonder no more.As I mentioned in my original post ,I have not been very keen on deviating from "traditional hardwiring" ,but after just 4 days in to a rewire (5 bedroom), I am astounded at the enormous savings on labour as a result of going wireless ,plus the reduction in moving furniture ...

    Are Quinetic still regarded as the best kinetic switches?

    Hi Folks.Have always appreciated kinetic switches for their "get out of jail"value in problematic situations.They are a gift .However my preferred approach is to always use traditional hardwiring where possible.I am now for the first time obliged to carry out a rewire where all light switching...

    Earthing Arrangements Explained + Photo's

    Well Dan,on your recommendation ,I decided to read this thread (all 12 pages of it). Very interesting.Feels a lot older than 10 years.It also raised a question for me ,based on the comment above from "Engineer54". He suggests that the metallic sheath of a TNS cable must be electrically isolated...

    NIECEIC or Napit reg.

    In some European countries ,rcd,s have been mandatory since the 80,s.Other countries felt uncomfortable with the introduction of the rcd ,which delayed it's introduction (Holland and the UK for example).Why the rcd became a little controversial in some countries is a question I have no answer...

    NIECEIC or Napit reg.

    Would that have been the norm for all sparks of your generation or were you ahead of the curve? I ask because when I first visited UK forum,s in the early naughties there was a noticeable dislike for rcd,s among British sparks.And even on this forum in more recent negative sentiments...

    How to identify presence of an earth electrode

    No.The reg simply states that rods sank in "public areas" such as footpaths may be covered in after the initial inspection.Our understanding is that the "powers that be" are concerned about anything that might be utilised as a "trip hazard". Yes.Metal covered in concrete lasts for decades.From...

    How to identify presence of an earth electrode

    here is where it gets interesting. You cannot ABSOLUTELY confirm that your reading confirms the presence of an earth rod.As you speculate, you could be getting a parallel reading.However ,realistically ,the only metallic services coming in to an Irish home since the 1990,s are....correct...

    Cable sizing earthing conductor

    Just spotted this thread.Sinking earth rods is probably the average sparks least favourite pastime. There is no calculation involved .If you install a 16mm supply (in ROI) you are obliged to run a 16mm earth to the rod.10mm is more than adequate (4mm is actually more than adequate).But the...

    How to identify presence of an earth electrode

    I have been mulling over your situation as I have recently been in the same predicament. We completed PIR,son 130 homes for a housing association all built between 2005 and 2019. Our single biggest challenge was the lack of earth inspection pits.The association insisted on "no remedial works...

    How to identify presence of an earth electrode

    Unfortunately not.Another peculiarity of the TNC-S system is that an open PEN fault actually renders your rcd,s ineffective in protecting you should you touch any live metalwork. The rcd does,nt detect the fault current flowing through you as an imbalance.Your only protection will be in having a...

    How to identify presence of an earth electrode

    It's to do with with reducing the "Touch voltage" under an Open PEN fault when all bonded meralwork in the home becomes live. There is a popular misconception that the rod can act as a " back up" when the DNO,s neutral breaks ,but this is not realistic with a standard single earth electrode.

    How to identify presence of an earth electrode

    Instead of disconnecting the neutralising link I would disconnect the unknown remaining 10mm earth ,which you can be virtually certain is going to the earth electrode.Carry out an fli test on it and you will likely get a reading somewhere between 100 to 300 ohms. Though strictly speaking there...
