514.11 Disconnects for dispensing stations need to allow for rapid response to a hose breakage or other event that creates a fuel-related fire or explosion hazard:

(A) Each circuit leading to or through a dispenser (including equipment for remote pumping systems) must have a clearly identified and readily accessible switch, located remote from the dispenser device, to disconnect simultaneously all conductors of the circuit including the grounded conductor if any. Single-pole breakers with handle ties shall not be permitted.


If there is a 120V, fractional pump (1/4HP) at fuel dispenser, what's type of remote disconnect we can use to disconnect both hot and neutral wires to the pump?
 
The last ones I messed with used an IEC style rotary switch with at least six poles so they could break all circuits. Controls, lights, pumps etc.

If it is in the panel just use a switched neutral breaker. Otherwise use a 2 pole switch.

I might add that from your desciption I'm thinking this is a simple combo pump/dispenser with no other light circuits, etc, as opposed to a full blown computerized dispenser with lights, etc and a remote pump.

Correct. Thanks
