Frequently asked questions

Portable Appliance Testing (PAT) is a process used to verify the safety and functionality of electrical equipment. It helps identify issues like insulation failure, earth continuity problems, and leakage currents that could pose risks to users or disrupt operations. Regular PAT testing supports compliance with workplace safety standards, reduces liability, and prevents costly equipment failures by catching faults early.

Megger PAT testers are designed for a wide range of electrical appliances, including Class I and Class II devices, IT equipment, extension leads, and portable RCDs. Whether you’re testing power tools on a construction site or office equipment in a commercial environment, Megger’s range has a solution to meet your needs. Models like the PAT250 and PAT450 also support IEC lead testing and high-voltage flash testing.

CertSuite PAT software connects wirelessly to compatible testers, automating the process of logging test results, generating compliance certificates, and storing asset data. This eliminates the need for manual paperwork, speeds up job completion, and ensures professional documentation is always available. It also simplifies retesting by tracking due dates and test histories, helping you stay organised and efficient.
