Megger PAT420 Business in a box

Megger PAT420 Business in a box

  Key features:

  • Dual voltage operation: 110 V and 230 V
  • Automatic and manual testing
  • Full colour QVGA display
  • Fast re-start
  • Convenient USB stick database transfer


PAT420 is the ideal PAT tester for those moving into PAT testing for the first time, looking to ensure all aspects of portable appliance testing are covered including construction sites using 110 V equipment. It has memory storage for 10,000 assets and can download direct to a USB memory stick for reading by PC. It has fully configurable tests with direct access via soft-keys, and a full QWERTY keypad for fast and precise data entry.


Push-button operation makes the PAT420 fast and intuitive to use. All test requirements are supported, including Class I and Class II, IEC power leads, extension leads and full trip-time tests for portable RCDs. Automatic testing proceeds sequentially through bond, insulation and operational tests, indicating a pass or fail at each test, with user-selectable PASS/FAIL limits. Should a fail occur, testing is stopped.


A quick-test key provides direct access to individual tests for diagnostic purposes. If a repair has been carried out or a suspect result obtained, just the relevant test can be performed so increasing efficiency. Each test is preceded by a selection screen where the test parameters can be chosen.


A selection of test leads are supplied, including a combined earth bond, continuity, and insulation test lead, an extension lead adaptor, and a special adaptor that makes it possible to test most laptop power supplies and leads.


Other options for the PAT420 include barcode asset identification with the optional scanner and label printer. Thermal-transfer labels provide permanent, resilient and robust labels for locally identifying asset numbers and re-test dates. A USB barcode scanner speeds testing by the elimination of having to type asset numbers into the PAT, enabling direct scanning, data entry and recognition.

  • Earth bond test (with lead null): 200 mA, 10 A, 25 A
  • Insulation test: 250 V and 500 V
