Electrical Testing and Tagging in Tamworth. We test and tag your electrical devices and cables to ensure they’re safe for you, your family, and your colleagues to use. Our licenced electricians use the Metrel DPAT electronic test and tag machine. All clients who use our testing and tagging services will receive a register of results and certificate of compliance. We will also send a reminder of when your devices and cables will be due to be tested and tagged again in compliance with AS/NZS 3760 standards.
