Our Portable Appliance Testing (PAT) service offers thorough inspections for both single-phase and three-phase electrical equipment using a PAT testing machine and visual checks to spot any damage or faults.
We provide a full asset register with ‘pass’ or ‘fail’ status for all appliances, giving you peace of mind and potentially lowering your insurance premiums. Contact us today to schedule your service and minimise the risk of electrical faults before they cause harm.
Electrical faults are a major cause of fires in New Zealand. Appliances with flexible cords and removable plugs are at risk of insulation or casing damage, which can lead to electrical fires. While most residential and office appliances use single-phase power, heavy equipment on construction sites and in factories often uses three-phase power. It’s crucial to regularly check any of these appliances using a PAT machine to ensure safety.
We provide PAT services for a wide range of businesses, including offices, supermarkets, rest homes, construction sites, manufacturers, gyms, restaurants, and schools. Whether you use single-phase, three-phase, or both, we can help you maintain electrical compliance by servicing your workplace.
Single-phase power uses a two-wire circuit: one phase wire and one neutral wire, creating alternating current. It powers most residential and office appliances like kitchen gadgets, laptops, monitors, and TVs.
We test these appliances using our PAT machine under Class I or Class II tests:
Class I – Appliances with single insulation and an earth connection, using a three-core cable with a metal earth pin. Examples: jugs, irons, toasters.
Class II – Double-insulated appliances with no earth connection, marked by a double box symbol. Examples: electric drills, hairdryers, computers.
A three-phase power supply consists of a three-wire alternating current circuit. Power is delivered consistently as it is transmitted at a steady rate. Some three-phase systems also include a fourth wire (neutral), but the system is designed to transmit a set amount of electrical power.
Three-phase power is commonly found in commercial buildings that use heavy-duty electrical appliances, such as manufacturing plants, data centers, ships, aircraft, and construction sites. To test three-phase appliances, we use our PAT machine equipped with a three-phase adapter.

Testing frequencies vary based on factors such as the appliance’s environment, usage, and industry health and safety standards. Typically, equipment will require testing every 6 months, 12 months, or 3 years, depending on these factors.
We offer affordable, competitive pricing based on job size and power supply type (single-phase or three-phase).
Unlike many electricians, we don’t have call-out fees and charge per tag, not per hour. Contact us for a free quote and pricing details.
Our service includes a full asset register report with pass or fail status for each item. We work around your business’s schedule and send reminders when your next test is due.
In New Zealand, businesses and organizations that use electrical equipment with flexible cords and removable plugs – such as offices, construction sites, and manufacturing facilities, should have their equipment tested and tagged to ensure health and safety compliance.
