QuoteElectrical meter bases, conventional mechanical meters and smart meters are not a source of ignition, and, as such, are permitted to be located within 1 metre of a natural gas discharge opening and 3 metres of a propane gas discharge opening. A meter is considered a conventional meter if it does not contain an internal service disconnecting feature.
QuoteI've attached ESA Bulletin 2-10-13 which provides further details on these types of installations. It also identifies which types of metering equipment is considered a source of ignition and which are not. Conventional mechanical meters and conventional smart meters (that do not have a service disconnect feature) are permitted to be installed within 1 metre as they are not arc producing devices. That being said, Rule 6-408 f) also requires the metering equipment to be in compliance with the supply authority. The local supply authority may want the flexibility to install any type of metering equipment available and may not permit the meter-base to be installed less than the minimum 1 metre requirement.
