Grounding metal garden room

A previous 'putting power into a metal shed' thread.
No.
This 'ground' description implies content created for North America. Inappropriate and unrelated.
No.
Sockets, lighting and other electrical accessories require a protective conductor which connects them to the main earth terminal for the installation.
Standard installation practice since for ever.
Extraneous conductive parts which includes items made of metal that are in contact with the Earth outside, or bolted to a concrete foundation, or are items such as metallic pipes which enter from underground require a bonding conductor between them and the main earth terminal. For a traditional metal framed building this would typically be a single connection to the robust metal frame at a convenient accessible point.
However given the construction methods of what is in the video, it's very likely that none of the parts are extraneous and no bonding is required.
Metal framed buildings are not caravans.
TT installations are not some magical solution to everything, and in an urban area with adjacent TN-C-S supplies it will be very difficult or even impossible to create a TT installation.
Bonding things where no bonding is required makes things worse, not better.
Don1t be put off for getting shouted down kiddo - Either they were wrong or you were wrong, all of us are capable of being wrong sometimes - to err is human.lad
Well I can pretty much agree with that.
Just one thing though "Metal framed buildings are not caravans." Yes that`s true, however there might be some merit to considering as if they are for pretty much the same reasons that we treat them to slightly different rules.
The decision is then whether to/how to Earth them and consider all of the pros and cons of such.
And as I mentioned sufficient connection both mechanically and electrically robust to be able to consider each touching piece to have pretty much the same polarity as any others in touchable reach. Once they attain the state of being substantially the same electrical properties we should almost eliminate step voltage problems into any equation.
Any bonding/not bonding considerations is pretty much a consideration of the lesser of the evils, which means inevitably not always a clear cut decision.
As noted, the OP only queries 'grounding' and yet everyone's replies (I think) only relate to 'bonding'.
IMO not quite.
OP asks about 'grounding every panel' etc
OP asks about earthing method.
My feeling is OP has little electrical knowledge in this regard and is treating bonding and earthing as one and the same.
This is certainly not a criticism and the reason he rightly came here for advice.

...and yet no one thought to explain.
No you haven't either.
Nor me!
I was not thinking of your reasoning. The OP said grounding, therefore...
He also said:
Another Americanism to which I did not respond.
I would assume that each panel is powder coated, why do (other) people assume there will be continuity?
Perhaps continuity might be achieved via the screws through the panels. I dunno.
I do not understand why posts on this sub forum become so combative- and fair play for ducking out- I don't blame you.
I normally play in my decorating sand pit. We might disagree with each other from time to time, but we are civilised.
I am not singling out anyone in particular but it often seems to be the case that these sub threads get to the point whereby the OP probably/possibly regrets asking the question.
I love this forum, and I will forever be indebted to the people whom have helped me in the past. I want this site to continue, to do so, it needs to generate income from eyeballs and advertising. Back biting, helps no one and, potentially makes it less enticing to new users. Without new visitors, this site will shutter. I have paid for server space in the past, the costs here are wayyyyyyyy higher, and then factor in the staff costs...
Perhaps it might be prudent if people with diametrically opposed views PM each each other rather than polluting our "play
ground".
Meh...I have just finished my 4th pint and need to shoot off. I respectfully ask each contributor to consider the continuance of this site.
Gonna leave the pub and shout at some pigeons...
Regards to all.
Equally a typical british builders comment.
