Cheers for the replies so far - its an aircraft manufacturing plant - pretty clean environment with no airborne dusts etc. The cabinet is sealed as in ATEX rated - though not sure of the spec.....its deffo a weird one
Non-electrician here. I'm looking to pick the hive brain and wonder if any of you have come across anything similar to the growth in these pictures - this was found within a sealed electrical panel located within a manufacturing environment. Any ideas what it could be?
Thanks in advance.
