Discuss Why? Is metal conduit so thick in the UK Electrical Forum area at ElectriciansForums.net
RS Components are selling 3m lengths of 20mm for £70.I bet that stainless or expensive
Rob yes we have to install a equipment ground in our conduit. We have several kinds of conduit schedule 40 PVC, schedule 80 PVC, EMT, galvanized, aluminum, and Rob Roy conduit which is conduit duped in a rubber coating inside and outsideAlso has to do with our conduit systems can be relied on as the circuits CPC.
In the US a ground withe must be run with the system.
...Used to use quite a few 3/4''/20 conversion couplers, still have some somewhere.we have 2 types of conduit. older stuff is imperial (3/4" or 1") later stuff is (ach, spit,) metric.1 fits and 1 does not.
Different grades of conduit are available, it's just unusual to find anything other than class 4 at most wholesalers these days.
I had the misfortune of having to pick up a couple of lengths from CEF a few months ago, it seemed incredibly soft to bend and thread, when I looked a bit closer at the writing on it I found that it was class 3 conduit.
Are you sure it’s conduit and not some other kind of pipeWhy so thick ,
My take on this is Iron / steel resist aprox 10 x worst than copper ... so it was needed for a Low Resistance (E)/cpc !
(and also gives a DIYer something to find with his drill )
@telectrix was that Spit / or split --bendy stuff !
I have had the same happen to me. Also at CEF. Probably charged the same as class 4 also.Different grades of conduit are available, it's just unusual to find anything other than class 4 at most wholesalers these days.
