Got a potential Ex failure on an external LV distribution board. Its an Exe board and has been in place for over 25 years.
Loads of cables enter through a brass gland plate at the bottom. The gland plate is threaded but only 4mm thick. Locknuts and IP washers are not in place.
The board is in excellent condition and bone dry inside.
So installed today to ATEX standards the gland plate would need to be a minimum 6mm thick for an installation like this.
Does anyone know what the UK standards were in 1994 when this was designed and specified. ATEX didn't make an appearance until 1996 and I understand wasn't mandatory until about 2003. 60079 would not have been around in 1994.
When did the 6mm thick bit come in?
Can I claim 'grandfather' rights on this?
It is a UK installation so American standards although interesting are not applicable in this instance.
Value your thoughts.
cheers
