By the looks of it, in the first pic they have used SY cable. That is not suitable for fixed wiring. With regards to the gland, they have just used a through gland. Would be interested to see if that have done anything with the screen inside the box..
In the second pic they are used SWA cable and so have used the glands specific (the ones with the black sleeving) for this cable and are not 'through' glands.

Different types of cable maybe? what is the IP rating of these glands? don't look right for E the application they are used in, in the 1st Pic the cable is SY think the others are FP200

I think the non swa are SY but they have been shot by the sun.

Could be right Mate SY is the go to cable for HVAC guys isn't it

in 2nd pic. might the not be stuffing glands but with boots on top?

JB: SWA via CWs, SY via stuffing glands
Isolators: One SY via what might be genuine slotted SY glands under boots, other SY via stuffing gland. In and out were probably done at different times by different people.
