What is the required distance range for a circuit breaker from the propane dispenser?

• A. 10 to 20 ft
• B. 20 to 100 ft
• C. 50 to 150 ft
• D. 100 to 200 ft

Answer: (B)

Keeping electrical equipment away from a propane dispenser reduces the chance that a spark or fault could ignite propane vapors. The safe distance should be at least twenty feet so any potential ignition source stays clear of the dispenser area, while not being so far that wiring becomes impractical to protect, connect, and shut off quickly in an emergency. About up to a hundred feet is allowed so the run isn’t excessively long, which could cause voltage drop and make emergency isolation less effective. So the required range is twenty to one hundred feet. Distances closer than twenty feet raise ignition risk near the dispenser, while distances much farther than a hundred feet create wiring and safety-control challenges.
