Grounding at Gasoline Dispenser

[Kohlhase]

Will driving a ground rod below a gasoline dispenser at a gas station/convience store cause any concerns? It will be connected to the dispenser. This is being accomplished at each dispenser.

Does anyone know what purpose it might serve?

 

[bphgravity]

It will serve no purpose.

I agree. No purpose served. See reply to your post under grounding.

Any concerns?
How about ground loops? Is the dispenser grounded to the panel also?
Could cause noise on the communication lines.

You are driving those rods before the product lines and conduits are installed right?
And not through the bottom of the dispenser sump?

In the past (15-20 years) driving ground rods seemed to help with reducing electronic board problems in dispensers that occured during storms with lightning. No one expects it to help during a direct hit, but lightning within a mile or two would often knock out some electronics and this was one of the solutions that seemed to help.

I believe the newer electronics are much less sensitive.

Multiple connections of the EGC to earth does not create ground loops or noise problems.
