Somebody help me please

For not clipping cables to joists?

Interested on how you do that on a rewire, very, very small apprentice.

Calm down, was only thinking out loud.

i know i could hear the brain creaking from here..

I was thinking of giving you a dumb, perhaps bad spelling (grammar really), or even just a plain 'old' (see what I did there) dislike.

But its BH tomorrow, peace on Earth and good will to all men etc

Any constructive ideas on my switch cover?

 

[Wilko]

but then you are introducing an earth potential where the wasn't one before, so could be more of a danger if as person is in contact with a live part and the pipe you've just fixed at a 0V.

Agreed.
But wouldn’t this be the same risk in every house that has water bonded to MET? Or have I misunderstood?

The new generation of sparks,will not bond now,cause that’s what they have been told to do.
Like someone said,we bonded everything in days gone by

does that exclude women and gender neutrals, or are they covered by etc?

As I see it there are two reasons to bond pipes.One is equipotential(where all the bonded parts have the same voltage flowing through them as the fault current rises to the point of the breaker tripping) or fault protection (where the pipes potentially become live but the presence of the earth wire causes the breaker to trip)

The risk of someone touching two metal surfaces while the voltage rises to a point of tripping (usually 0.4 seconds) is surely un-heard of.
So much better to bond and guarantee the breaker or rcd will trip compared to the pipes becoming live waiting for someone to touch them.
People on here have pointed out that the boiler should be earthed.
0.75mm green yellow is hardly fool proof protection in my opinion.Much better to have a 10mm bonding cable as back up if the boiler wire gets disconnected.

but the breaker will trip as long as the (earthed) exposed metal part that has the fault, regardless of any bonding.

Who are we protecting ,customers , or DNO from lightening strikes getting coupled too well back into supply !
(what next fancy quenching fuses in neutrals )

I'm currently having a complete central heating system installed along with a rewire. Pipe work will be all plastic with the exception of the radiator tails and the first metre from the boiler as per manufacturers instructions. Incoming water main is plastic and will be joined to new plastic supply to bathroom and kitchen. I don't have a lot to bond but would be interested to know what the electricians take in this will be.. I'm guessing it will be just bond the gas!
