How to tighten a 50mm SWA gland with no access to locknut

[Wilko]

If you just can't get it - gland into trunking perhaps?

I would have but the other contractor has cabling which prevents this

So with all the usual methods being impracticable I am down to just finding a way of tightening them up in situ

Sounds to me that your options are limited to making off into some trunking, then feeding the conductors through the trunking into the panel, or to removing the cables that are blocking access and then replacing them once your cables are installed.

It's a crap job alright
as I said earlier trunking isn't an option as there will be panels either side , and contractor already has cables in situ effectively blocking the rhs ie he has large singles at the rear and at the front leaving a gap in the middle which makes it impossible to install my larger sized cables
I pointed out to the customers engineer that
a) he'd installed in such a way as to make things impossible for me
b) he'd installed singles into steel plate thru separate glands

So I just have a small area at the back into which I have put a 25mm on the LHS coming off tray on right
Contractors singles also on same tray
I have used a small area for 15 small cables crammed together where I can cable tie the inner cores in sheath to panel frame out of the way

I've left the area with a clear drop inside for my larger cables which will approach the panel overhead on tray I've installed

The "Engineers" thought I could put 4 x 50mm5c, 1 x 50mm 4c ,1 x25mm5c, 4 x 16 mm5 c, 17 x 2.5/4.0mm cables from the side with a low ceiling height

I'm confident I can get these cables into the panel now I've added tray at the front , it's just tightening the locknuts is the problem however I'm going to try the method I've already used cutting serrations into the locknut, but with Marvos idea of a second locknut on top to tighten

I'll try and upload pics

Thanks for all your help it's much appreciated

Can’t see any problem with tightening that gland.
Just need long arms.

Insulated bus bars, nice.
Quite rare.
