Oil terminal wiring

[powersystems]

Hi guys,
We are doing some work at an oil and diesel fuel pump terminal. They relocated two pumps that pump the fuel from the holding tanks to the terminal. The pumps are not explosion proof and the starters that control them are in Nema 1 enclosures. The service (including the starters are under the terminal canopy inside a plywood doghouse and the pumps are about 10' away just outside the back wall. Is there any reason that the wiring for these pumps would need to be explosion proof.

Thanks,

Kevin

When you refer to "oil" in your first sentence what types are you talking about? In general, "heavier" oils like diesel don't require electrical area classification. Kerosene and some lighter jet fuels are technically oils that need classification attention. We need a little more detail to give a complete answer.

I would suspect that the inspector might want to see an Area Classification Drawing depending on the materials.

Check out Appendix D of API RP500 to get an idea of point source Area Classification and what is required to determine a hazardous location.

To reiterate what Bob said, it makes a big difference on what materials are being pumped.

Thanks guys,
It is only Diesel fuel and #2 heating oil. I dont think either is classified, plus it would be a joke seeing what is on the line and load side of the piping I need to install. i just feel like I am missing something. All of the controls (lights, switches, stop/start etc.) up on the platform are ep but not the starters or anything in the cabinet where I am coming from.

Thanks again,
