My brother in law had two 300 gallon, above ground tanks delivered to his landscaping business, one gas, one diesel. I have hooked several diesel tanks up and had them inspected ect (all went well) but this senario is different and I have questions: the two tanks are 12' from each other with the 7200 volt transformer feeding the building in the middle of the two, the gas tank is 4' from the service and meterbase coming into the metal pole building. Since they are this close, I think both are Class 1 wiring? he claims the oil company that delivered these are saying if it is less than 300 gallons, they are not!! (I guess 300 gallons of gas is less flammable than 1500??) both of these tanks have a 6' cord and plug on them, (thats how he wants them wired) also there is no spill protection, they are just sitting on the ground, not in any dike or double walled tank ect. Would both tanks have to be considered Class 1 and need an e stop circuit with a switch at the pump to brake the hot and neutral? I dont mind wiring the diesel tank, I wish the gas tank was not there!
Thanks
