Thought I was onto a real winner today when checking the gas bond to find a nice bonding conductor run directly to a local earth rod:
The main house is currently TT with a rod on the opposite side of the house, so maybe they thought the foundations counted as a massive MET :rolleyes:
Was...
Afternoon
A simply question but like confirmation from the more knowledgeable. Can someone confirm if there is a direct short between a line conductor to extraneous pipework I.e water or gas. In what scenarios will the MCB trip or not trip? My own thoughts are that if it has a negligible...
Hello All
Noticed the existing bonding for the cold water supply is only 4mm. The supply pipe out of the ground is clearly a plastic pipe. It joins a brass stopcock under the kitchen sink cabinet and the rest of the plumbing in the house is in copper. I'm worried I need 10mm bonding and will...
Could somebody please put me on track.
Main bonding conductors are sized relevant to earthing conductor (TN-S / TT) or PEN conductor (TN-C-S).
On a large installation (Industrial / Commercial) with multiple buildings containing Extraneous parts should ALL the bonding conductors be sized the...
Hi Electricans,
I am a homeowner with an earth bonding question I am receiving conflicting advice upon and hoping someone can help point me in the right direction.
A few years ago I had a full bathroom replacement via my insurance company and a bathroom installation company they supplied...
Yes, it's another EICR coding question - hurrah! :blush:
Inspecting a small 1 bed 70s ex-council flat that was going well. Main Bonding had been put in place in advance and most of the tests were as perfect as you could get. Seriously, if you wanted to set up a 'perfect' test rig I don't...
Adding a socket in a house where the downstairs bathroom fitters appear to have boxed in the original stopcock and 'moved' it sideways into the garage, but not moved the original bonding cable. It's now firmly inaccessible behind the toilet. The cabling at the consumer unit is also unclear...
Morning!
Going to be working near the coast and will need to fit earth bonding outside.
I originally chose stainless lugs to bond the copper cables but it appears that stainless and copper are not a good mix due to corrosion so I will stick with the standard copper connections.
I have seen...
Evening All. I've been having a debate (argument) on a FB group with another well respected spark, and my old tutor. The subject of discussion - supplementary bonding.
Their opinion is that it is required throughout an installation, where ever the conditions in 415.2.2 cannot be met without...
Hi all.
I have a gas pipe to bond. The client isn't keen to have the cable run internally, so I plan to run it around the outside of the building. In conduit is one option, but will look at bit ugly IMO, so am considering clipping the 10mm direct. Anyway, it's thrown up a couple of basic...
Hi, just doing an inspection on a large block of flats. All the gas metre are in a single store cupboard on the basement floor. All are 10mm bonded there within 600mm. There is no earth bonding to the pipes entering the flats themselves. Is additional bonding required within each of the flats ie...
The present small job is in a unit, one of 40, in a single story Victorian mill.
The construction is cast pillars and beams in a roughly 6 meter grid
I cannot find any evidence of the steel being bonded, the site is huge and it seems unreasonable to spend days sorting this for a few sockets...
Hi guys, I need to bond the gas and water at a friends house..never done it before as I worked mainly on sites. My times just out, where’s the best place? Gas meter is outside in a Box so would I just clamp onto the metallic side just before it enters the house? And the water, not entirely sure...
Hi everyone ,thanks for letting me join.
A little about myself first, only do part time work now as getting to that age 60+;)
been in the trade for 3o+ years doing contracting ,council,shop fitting and factories.
Yes there has been a lot of changers since i was on the tools, some good and some...
Been asked to look at outdoor socket for spa. A brief perusal of M.I. recommends the installation of equipotential bonding in 2.5mm² solid copper. Now apart from the idea of non flexible cable, what purpose may it truly serve. It is supplied with a cable that has a 10ma trip in it. However we...
Evening All
I’m doing a few EIRCs for the rental market and I thought I’d share my recent experience. I was asked to inspect a 2 BR flat, just on 5 yrs old. The flat is in excellent condition, it has always been rented and has the original EIC and the most recent gas safety cert.
Both...
A friend may put his house on the market. He had a new CU fitted 8-10 years ago. Double RCDs. An earth cable goes from the incoming supply to the CU. The CU is under the stairs. I noticed that the gas outlet pipe is bonded to an adjacent water pipe that disappears under the floor in a cupboard...
Thanks all - looking for some perspective on this....
Friend had complete GCH system installed for a renovated rental property and was all certified at the time. At the annual inspection for the gas cert, the checker stated the bonding was in wrong position and quoted 100 to move it (which was...
I was recently watching John Ward's video series on Electrical Installation Testing. In the part where he discusses measuring Ze, he states that you only test the earth connection to the cut-out and need to disconnect it from the bonding and the CU to do this correctly. In his example diagram he...
