Article 514.11(A) states:
Use of the terms "switch" (singular) and "disconnect simultaneously" it appears that it must be one switch that disconnects all power. So what if there are more than two circuits that need to be disconnected. The enclosed emergency stop switches I've found can accommodate no more than two stacked DPST switches. Since both the hot & neutral legs must be broken, that's one DPST switch per circuit, thus a maximum of two circuits.514.11 Circuit Disconnects.
(A) General. Each circuit leading to or through dispensing
equipment, including equipment for remote pumping systems,
shall be provided with a clearly identified and readily
accessible switch or other acceptable means, located remote
from the dispensing devices, to disconnect simultaneously
from the source of supply, all conductors of the circuits,
including the grounded conductor, if any.
Single-pole breakers utilizing handle ties shall not be
A second question I have is regarding the circuits that are affected by 514.11(A). Our fleet dispenser requires two circuits (one 230VAC circuit for pump motors and one 115VAC circuit for electronic controls, solenoids, & dispenser internal lighting). Outside the dispenser, we are installing hose reels with power rewind (115VAC). Would these hose reels be considered on a "circuit leading to or through dispensing equipment"?
