The earth straps we only install in certain conditions, generally speaking your earth continuity is more then sufficient via the manufacturers fixing points. The last time we used these it was a job for one of our local rail networks and they required ever single trunking, bracket and tray joint to be earth strapped and torqued up.
The internal, external 90`s and the flat tee you demonstrated are the guset versions but you can get tight accessories as well.
I always used to install Earth Straps on metal trunking. It was drilled into us at college. Thanks for sharing. 🎅
I remember when going to the wholesalers you ask for a particular item, say an internal bend you were handed an internal bend now most counter staff and wholesalers don’t have a clue what we are talking about when it comes to accessories. The manufacturers really should get to know the onsite terminology and label there products accordingly. After all they bang on about making products to make our job and our lives easier. .
Great video guy’s as always 👍
7:57 Those earthing straps are par for the course on any job I work on. Just makes sense to have redundancy in your earthing so that if, somehow, the trunking does part company at one or more joints there is still a continuous low resistance pathway to ground. Just one less thing to worry about...
Like you Joe I've never seen a coupler to rotate the trunking 90 degrees 😳
Regarding the Earth straps it always used to be par for the course, every length used to be supplied with them. These days we think a bit harder about why we do this and in a lot of situations it just isn’t necessary, we use CPC’s….
I use Copper earth straps in industrial settings
Those clip on lids look neat, not sure how I feel about them not needing a tool to remove.
That being said the amount of trunking you see with the lids hanging off or completely missing because the turnbuckles have vanished or were never fitted it'll be a million times better than that!
Also you've had this one stashed for a while - uploaded a year ago?!
Been around years now; most lighting trunking has this design I find it much safer than potentially hitting the cables turning those screw lock things in
@@user-wk7wv8rn8h good point, I've definitely suffered from that one before. Thankfully only new trousers required ;)
