Yeah was looking to show the apprentice as he couldn’t believe that busbars without flasguards were ever allowed to be exposed inside a DB. I’ll never forget the first time I saw one as a young apprentice the big old 3 phase DB with the 4 busbars in the corner with absolutely no covers other than the hinged door it filled me with dread
we had to drill and bolt tails to the busbar to install a small DB beside to feed sockets for a computer lab in a school. Then we got asked to go back and make flashguards for the board ended up with a massive sheet of Paxoline with the whole cut out for the breakers and the isolator wish I had taken pics the schools gone now so there’s not even an opportunity to go back.
Seen a few of them in the same school as well but they had these big double wide beasts that had an big isolator fed off about 300 mm or so of busbar (with the armour coming in and bolted to it) and similar to the bottom pic on right hand side don’t know if these were specifically made to order but I doubt it...
If course it’s all in the size of the toggle I believe that the smaller toggles are type 4 and the wider toggles are type 3 but to be perfectly honest it could be the other way round I haven’t clapped eyes on an old Dorman since 2013 except the old Do(o)rman at the pub see him all the time
anyone else even ever seen one of these I’ll try dig out my apprentice logbook pretty sure I drew a picture of one in there in an entry about safe isolation
That is one way depending on the age of the Type 3. In all cases the Type 4 has ridges either side of the toggle and the Type 3 is smooth.If course it’s all in the size of the toggle I believe that the smaller toggles are type 4 and the wider toggles are type 3 but to be perfectly honest it could be the other way round I haven’t clapped eyes on an old Dorman since 2013 except the old Do(o)rman at the pub see him all the time
Nice didn’t know that haven’t seen one in years now though as all of the old buildings that had them round here have been knocked down
