Specifies safety and performance requirements for general purpose single-rate and multi-rate induction watthour meters with terminals arranged for bottom connection or with contact blades arranged for the meter to plug-in to a socket conforming to AS1284.4.

This Standard specifies requirements for general purpose single-rate and multi-rate induction watthour meters (hereinafter referred to as ‘meters’) for the measurement of 50 Hz a.c. electrical energy in domestic, industrial or commercial premises.The Standard specifies terminal arrangements and connections for bottom-connected meters, also contact blade arrangements and connections for single-element single-phase 2-wire plug-in meters by cross-reference to AS 1284.4.NOTE: This Standard includes guidance to purchasers of meters. Appendix A provides information which should be supplied with enquiry and order to facilitate the specification and purchase of meters.
