This photo make no sense to me whatsoever!! We have a full on flanged EEX'd panel that i imagine is mounted within a hazardous area, and directly underneath we have two bog standard metal clad twin sockets??

So Ollie, please explain what the hell's going on here???

The Exd Enclosure you are refering to is infact a Combined pressurisation, fire and gas panel. Now this is mounted inside the winch cabin itself which, once all the cabin doors are closed we can purge for a minimum of 3 minutes the unit to create a positive air pressure inside the unit compared to the outside. This means that gasses wont be ables to enter the cabin, once purging is completed the inside of the cabin is then deemed as a safe area and therefore the safe power contactor inside the cpfg panel is energised and allows non Ex circuits to be used. If there is a pressure loss or a fire, then all Non Ex circuits turn off.

The only circuits that are Non Ex and are still power in this event are the Intrinsic safe (very low current) circuits - Smoke/Gas detectors, alarms and break glass etc.

Thats the basics to why,

Ollie

That's a fair enough explanation Ollie. ...Thanks lol!!

Good question, good answer

I was brought up with intrinsically safe circuits as an apprentice. They don’t make life easy.

Knowing that if you make a cock up you’ll be sat on a cloud with a harp makes you take that extra little bit of care.
