Roofing Bolts as Earthing studs

[Andy78]

should be using a pozi2 mate instead of a philips.

why is there so many different types anyway?

ph0,1,2,3
pz0,1,2,3
then
phg etc who carries all these bits with them honestly?

Me.
I have PZ0,1,2 and 3 in VDE drivers in my main box. Around a hundred different heads of all sorts that fit in my ratchet driver, PZ, PH, Torx, Allen, small sockets etc, and also a full set of security bits. Hardly takes up any space at all and invaluable sometimes.

I have always found the best tool for roofing bolts is your largest flat driver.

Yep, everybody has a big yellow or a big red which occasionally needs a look at a grinder.

20 pence piece and pliers/grips anyone?

 

[Rockingit]

Just out of interest, what are people using to bolt tray together with?

tray couplers and 12mm roofers

tray couplers and 12mm roofers

Same here

Hmmm..... That's what I thought. So we're happy to trust them for earth continuity of one thing, but not another?

 

[Engineer54]

As far as i remember, all construction/containment type bolts on this project is spec' stipulated to be stainless steel, can't remember the minimum grade mind... Same goes for specified electrical connections, eg,.... bolts/washers/ and nuts, all Stainless steel

No I'd be happy to use them to bolt up a banjo if that's all I had

 

[Rockingit]

So, that then HAS to beg the question of why is it that we get hung up over using Brass and also paying through the nose for it?!

Cable tray isn't required to have any earth continuity, or even be bonded.
Whereas the connection to the banjo is a connection of the CPC.

So its not an exposed conductive part then?

No. You can't run unsheathed singles on cable tray.

We test to confirm that all cable tray/cable basket/cable ladders etc, possess suitable earth continuity values throughout their length. I can't recall a single project that i've been involved on that hasn't called for earthed continuity of any of it's metal containment systems.
