water in an outdoor JB and effect on SWA glanded in on the lower edge

psychicwarrior

Outdoor electrics tripping out and located to a JB (above ground) with water in it  (not clear if its condensation [seemed a lot for that] or a failed stuffing gland on the top edge - favour the latter)

Box emptied and dried out.  however,  the outdoor SWA glands on the bottom edge were obviously soaked and water must have seeped down the 3-core (one as cpc) cable (which goes underground).  Armour tied to cpc at both ends.

Just curious on other folks experiences on whether cables ever dry out (to some / any extent)  and whether will perform fine for lifetime  ?

thank you

    I had to replace a metal distribution board a few years ago. It was connected by SWA to a junction box 5m away and 1m higher. Water had got into the junction box, run through the SWA and into the distribution board in sufficient quantity to turn it to rust. Once dried out the SWA tested OK, but maybe it's life was shortened.
