A smear of Vaseline?

Vaseline is fine in high pressure contacts, as it gets driven out at the point of contact - copper slip is less satisfactory as it actually slightly 'gritty' at a microscopic level. The Vaseline complication is that it is highly inflammable - you do not want to get it to ignition temp (at a push it makes a reasonable fire starter once massaged into the cotton wool balls from the 1st aid kit when you are on camp and it has rained on the kindling)

I have been known to either heat or dissolve Vaseline in IPA to make it runny enough to paint it onto things post installation.

But how is this box vented - a lot of water in the box problems arise from poor venting strategy ideally you want pressure equilisation without damp air being drawn in.

There was no provision for drain holes when the isolator was fitted (unlike various makes of external sockets) and none had been drilled.  Venting was via a rear mounted 20mm PVC conduit which led through the wall beneath floor level.

My intention is to drill a small hole in the bottom face of the isolator and to seal the 6mm T&E in the PVC conduit (Plumbers Mait non-setting putty).

Would silicone grease be a good choice to smear on the cable end and terminals before tightening?

Apply Prysmian's R391 compound after termination? Not used it myself; just saw it while looking up the jointing pastes we use but I don't think it's designed for liberal application over the finished joint and this comes with a voltage rating for the avoidance of doubt.

NB: No link to either Prysmian or ETS
