I think you have highlighted the need for people undertaking the work to have a knowledge of basic electrical science. I teach PAT and go through this with all my learners
ANYTHING METAL CAN BECOME CONDUCTIVE, so I totally agree with your reasoning and direction - how I was taught and execute full testing for almost 10 years now. Best to be safe than sorry! Excellent video!
Thanks for the video, you mentioned that you shouldn't use the full 500 v insulation test on sensitive equipment, how do you know what is sensitive and what isn't?
Hi Ben, wonder if you could clairiy when an item would "power up" and are there any dangers to this. Alternatively do you have a video explaining this. I have literally just started using a KEWTECH Smartpat. Many thnaks again. AJ
an item would only normally power up if you were conducting a functional test or a leakage test via your machine. It wouldn't power up on the earth or insulation resistance test.
Hiya! I was told told on my course if there are no exposed metal parts then to place the probe at the cable entry point. Would that ever pick anything up do you think? x
I'm.confused I use preset 2 on same appollo tester to test class 2 hoover but the hoover doesn't actually power up when the power switch is on during the test?? Is this incorrect
It doesn’t sound like your mate knows what he’s verifying when PAT testing. Even though an appliance may not have an earth connection, it may still have exposed conductive parts. When you know what could go wrong, you realise how important this test is. Earthed appliances should trip or blow the fuse when voltage goes down the earth, with a Class 2 appliance, the voltage will just sit there on the exposed conductive parts waiting for someone to provide a path back to earth.
