UL 495

Abstract

Scope: These requirements cover power-operated dispensing devices intended to be installed outside of buildings and used at service stations for dispensing liquefied petroleum gas used as an engine fuel. Requirements for installation and use of these dispensing devices are included in the Liquefied Petroleum Gas Code (National Fire Codes, vol 2), NFPA 58, and the National Electrical Code, NFPA 70. These requirements cover wiring methods used to install or interconnect control equipment when the equipment is located directly on or within the housing of the dispensing device. These requirements do not cover control equipment that may authorize, monitor, or interrupt operation of a power-operated dispensing device. Such equipment includes panel mounted equipment located adjacent to the dispensing device, remote consoles located inside a permanent structure, and auxiliary equipment physically attached to the dispensing device or enclosed by the pedestal and housing.
