Picture of the week!™

... and the tube wouldn't get earthed.

And more often than not, the sharp edges wouldn't be protected by grommets.


See it all the time

It seems we've gone full circle with steel conduit as I saw the country's biggest electrical contractor installing this stuff on a multi million pound job this week....

 

[seasickstevie]

Has that guy never heard of cutting fluid?

 

[Echo the husky]

I've never seen someone make such a meal out of cutting a thread! I saw this 'system' installed somewhere last year, total crap, all the joints were loose.

I also recently came across a conduit system I have never seen or heard about before. It was metal pipe, standard conduit boxes, but a sort of male adaptor was crimped onto the ends of the pipe. Was installed in a boiler room in a house.

Can you rely on those minute grub screws to give good continuity when using the conduit as a cpc?

 

[Echo the husky]

The adverts used to say you could, but I wouldn't dare. Not that I'd ever use this rubbish!

 

[ban-all-sheds]

I expect plumbers said the same when plastic pipe and push-fit first came out.

 

[sparkwright]

Even if the conduit is not used as the actual earth, would I trust the grub screws to earth the conduit?

Can see some advantage in this stuff but it's just inferior to the real thing.

 

[sparkwright]

IS IT WATER-TIGHT?

It can't be.

Crap then.

 

[RF Lighting]

The conduit must be reliably earthed as it is an ECP and from what I've seen of it I'd be very doubtful if this was the case.

It would be very interesting indeed to test this system after a few years in service with the old fashioned high current conduit tester.

Anybody know what the standard referred to in the video is for?

This sort of stuff?? Scroll to the last four items....

They don't seem to sell a tool to crimp it though.

Which standard? Can't run the video on my phone.

Certainly looks like it! How unusual.
