In another thread I've been introduced to the joys of Electrical Gels used for sealing external junction boxes. Are these Gels proof against your averages spider, ant, or rat?
When we moved here we inherited a courtyard nicely lit by ten lights on various walls and brick pillars, and the plonker who installed them used SWA cable embedded presumably as the walls and pillars were built, without glands, into galvanised internal junction boxes. In times of heavy rain we get the occasional RCD trip not surprisingly.
I would replace them with waterproof boxes and proper external SWA glands, but the length of cable sticking out of the masonry is not long enough. So I've been considering using a suitable box and injecting insulating Gel.
Now in a recent "cleaning and re-insulating with self amalgamating tape" exercise the main problem seemed to be spiders and other critters getting into the boxes and dying. So if I fill new boxes with Gel am I just giving them a free meal?
