Re the top pic, we have similar but where there are only two cables to be joined we tend to use klippon type bus bar rails and an empty enclusure.
How is the earth continuity done lec?, it isn't clear from the pic.
Separate earth is run along side and will be lugged and bolted. Banjos on outside of busbar, bolt hole is in line with flange bolt ready for lugging.
This was a "what do you have on the shelf" type job. A resin cold pour would not be a solution.
To be fair, I noticed the busbar was upside down when I look at the phase rotation of the busbars. Blaming that on the boss who fitted the uni strut and busbar!
Top board is a merlin. Crap design tbh - door hinges down, not L/R. Gets in the way.
The board was rushed, prefer a night RF job - lol. No excuse for the rush other that simply too much to do to worry about photographic quality workmanship!
I dont think RF was referring to the chamber being upside down, more the wording on the label 'busbar supports must not be used for the termination of cables ' which they clearly have been !!!
The wholesaler only had a busbar in stock, and this was a "has to be done" job. I did order a couple sets of terminals, and *should* be able to fit them....Although, TBH, from experience, they are the same as the spacer ones anyway, and very similar to the support ones too.
I could always drop the busbars and bolt the two lugs together
