If you wondering how to perform portable appliance testing (PAT test) on 110V portable appliances with a 230V PAT tester without a 110v socket… here’s how!
Patesting manufacturers will always supply (as standard) a 110V test adaptor with 230V PAT testers that do no include a 110V socket. This enables PAT Tester to include 110V portable equipment in their testing regime.
Portable Appliance Testing (PAT testing) 110V appliances can be done on a limited but satisfactory basis. The portable appliance tester like other equipment runs off a normal 230V supply and is not able to supply full power to do any kind of load/leakage test. The load test would need to be done externally by plugging the 110V equipment directly into the 110V power supply, to confirm the equipment is functioning correctly.
In relation to PAT testing 110V extension cables/reels the polarity checks cannot also be carried out. The live is shorted in the 110V adaptor supplied for safety reasons, this is to avoid powering up 110V with a 230V PAT tester (portable appliance tester). In this case you would need to check the wiring with a continuity tester or open the plug and have a look!
