This might be a stupid question

[DPG]

I still can't believe anyone is going to provide every piece of a suspended ceiling grid with adequate earth bonding.

Whilst you may not "have to" if you are concerned ?
Then there is nothing stopping you from doing so !

Other than common sense.

It still is in a lot of spec's we have and most of them seem to be generic except for a few pages. Is there anyone on here that used to have to do it? I remember when I was an apprentice or just after around the 15th (brown book) bonding all the pipes under a combi boiler (that all connected onto a metal bar) makes you wonder what the people writing the regs was thinking.

Talking to a new bloke today that said

"This might be a stupid question "

I said straightaway " No such thing as a stupid question "

He immediately says
" Do you like sausages?"
.......................
"Ok I'm wrong there is such a thing as a stupid question!"

Do you?

I've done that many times Anthony, continuous 10mm all the way across with insulation stripped at each earthing strap and all with the same 'loop' between.

 

[Toneyz]

I have only seen it cross-bonded with 4mm earth to each main T bar.

 

[Dave OCD]

I always used 10mm, sometimes just continuing the main gas bond unbroken across all the pipes.

How often do we find poor R2 readings in shop overhead lighting ?

Tricky one that. Having received 120v shock between the metal grid and the earth on the klix fittings it is something to consider carefully. The building in question is steel girder and metal roofs with block work and concrete floors. There are three buildings on site and two had this problem. We have in one set jack chain and fluors off of metal girders/roof trusses all metal. In the other Cat II 600 x 600 fluors. One of the failures in the original install was the fly lead from SWA gland and earth bus bar was not installed. It took some thinking about to obviate the problem. So I would say careful consideration and testing before deciding one way or the other.

When in doubt bond it

We do things differently over here; we only bond something if it’s extraneous.

NOT taking the P--s Megawatt, grateful if you could set my mind at rest , what constitutes a Master Electrician in the US or Canada? when I was working short term in Canada, I got told by the sales person in "Home Depot" you can't have such and such unless you are a Master Electrician, so I asking out of genuine concern, no intention of deriding the term in any way just curious.

A master electrician is someone who has moved past the apprentice and journeyman stages of their career. ... A journeyman electrician will not have the same experience or licenses as a master electrician. Journeymen may be able to work independently, but do not have complete autonomy.

Basically, just experience, and a different license.

Journeyman would be in my eyes, when I finished my apprenticeship, I was considered an improver for a year after. Qualified, but still needed to pass designs etc through someone more senior.
