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

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

  • The cables may dry out to some extent but the life will not be greatly changed although the armour may suffer a very small amount of corrosion. Armour corrosion requires that the water is changed frequently as once it reacts with water the water is unreactive, and Hydrogen is given off.
