UL 87A-2015 pdf download – Power-Operated Dispensing Devices for Gasoline and Gasoline/Ethanol Blends with Nominal Ethanol Concentrations up to 85 Percent (E0 – E85).
3.6 DISPENSER, BLENDING – A dispensing device that is provided with a blending option 3.7 DISPENSER, REMOTE CONTROL TYPE – A dispensing device that does not contain a power- operated pump as part of the assembly, and which is intended for connection to a fluid piping system containing the power-operated pumps at a remote location. Also commonly identified as a “dispenser”. 3.8 DISPENSER, SELF-CONTAINED – A dispensing device that includes a power-operated pump as part of the assembly. Also commonly identified as a “pump” or “suction dispenser”. 3.9 DISPENSING DEVICE – A product consisting of various components as applicable, which are used to control and meter the flow of liquid from an upstream storage device. 3.1 0 ELECTRICAL CIRCUITS – a) High Voltage Circuit – A circuit having a potential of not more than 600 volts and having circuit characteristics in excess of those of a low voltage or Class 2 circuit. b) Low Voltage Circuit – A circuit involving a potential of not more than 30 volts ac (rms) (42.4 volts peak or dc) and 1 ) Supplied by a Class 2 transformer, or by a battery, by a battery and fixed impedance, or by a transformer and fixed impedance each of which, as a unit, is in compliance with what is required for a Class 2 transformer, or 2) Limited to a maximum of 1 00 volt-amperes. A circuit derived from a source of supply classified as a high voltage circuit, by connecting resistance in series with the supply circuit as a means of limiting the voltage and current, is not considered to be a low voltage circuit. c) Intrinsically Safe Circuit – A circuit incapable of releasing sufficient electrical energy under normal or abnormal conditions to cause ignition of a specific hazardous atmospheric mixture. Abnormal conditions include unintentional damage to any part of the equipment or wiring, insulation or other malfunction of electrical components, application of overvoltage, adjustment and maintenance operations, and other similar conditions.
