Check the attached photo of a gasoline station.
The two panel boxes at the center of the photo (in the corner of the station) are standard panels (IP-67), which enclose standard circuit breakers for the main gas pumps of the station.
They are less than 7 linear meters on separation.
I would like to ask you, if you have experience on electrical EX-proof facilities:
Is there any mistake here? Or is everything right according to the EX-proof codes?
I see nothing in your picture to indicate that the circuit breakers need to be explosion proof. They don't appear to be in a zone 0 location, nor would I expect that any explosion proof volume would extend thru the conduit to the circuit breakers. That just doesn't make sense.
Also, cars aren't zone 0 rated in the first place, and neither are all kinds of things you are allowed to have in the car and on your person while filling up at a gas station. The protection is between the gasoline and where you can get at it, not in the zone around the pump.
Your whole concept doesn't make sense.
