Hello Code Question of the Day.
Is a electric meter considered source of ignition with a propane tank or regulator?
Yes. Propane tanks and associated regulators have hazardous (classified) locations associated with them, and must meet the location and area classification rules in Articles 514 and 515. See Sections 514.3 and 515.3 for the classification of the areas. See Sections 514.4 and 515.4 for requirements and restrictions of equipment and wiring in these classified locations. It is best to locate the meter away and outside of any hazardous (classified) location.
