21-0512 International Equivalency - Voltage in NZ

Standard voltage rates vary country by country - in general, project teams may assume that any small appliances, equipment, and lighting that are plugged into the "residential voltage" electrical supply listed in this table are considered low voltage and therefore out of scope. All hardwired and hard-piped equipment and appliances, and plug-in equipment and appliances with a dedicated electrical circuit or that use voltage equal to the service voltage, are considered in scope. The exception is hardwired equipment that is low voltage, typically 50V or lower and requiring a converter, such as for doorbells, garage door opener controls, heating and cooling thermostats, alarm system sensors and controls, some digital equipment, and some high efficiency lighting.
