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

Inside the p shape marked in pencil is where I can gland into

One of the mechanical guys onsite is 6'7" and he can only get his fingertips near the centre,
What you can't see on pics is an 80mm post either side of the panel which means you need to double jointed too!

Hi - do you know roughly the load on those singles?

I take it the panels are not aluminium or made from a non-magnetic alloy?

Panel built in France nice job it's just a shame the sparks glanding into it have made things difficult also no one told the guy that built it that there was no clear access from above,
it's meant to have a trench which it would have had a 12" trench below ( still no good to me)
But they decided to move the Panel onto another wall anyway

I'm back onsite tomorrow I'll get some better pics then

Would it be possible to install the glands before connecting the cable using a socket inside the panel and a spanner outside?

It's definitely steel but those magic glands mean it's not a problem

I offered to redo those cables and run them all nearer the back to give myself more room but was told it wasn't possible yet there's plenty of spare cable at the other end

This confuses me...which isn't difficult. The photo is a bit blurred, did they cut a slot in the panel between the bushes containing the singles or is it just a pencil mark they left?

Nice looking panel by the way, shame there wasn't a routing and glanding plan done in advance.

The load isn't huge our engineers who are controls engineers massively oversized the cables ( I've had words)

This will make you laugh they basicly add up all MCB ratings in the panel no diversity at all they've obviously never been involved in quoting

This isn't our normal job but we've been asked to do it as part of the job and their guesstimate came in at less than half the quote from a French company
As I've hot experience with SWA it's become my problem

I've had this discussion before and put clamp meters on all the panels under full load on other jobs and shown them

2 of 50mm cables could have easily been 16 mm to be sure they could havevused 25mm if it was borderline which would still be oversized to allow for any future load increases which will never happen

The others are sized about right with the Volt drop
