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?
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
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
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.
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.

On the fan the ideal test point is the shaft that connected the motor to the blade
Great video Ben! thanks for the advice, love your videos, keep them up, ive learnt so much from your videos to be able to do my job better!
thank you!
G'day, Do you have an example of a classc 2 item that has failed with the earth brobe attached?
Thanks
I've applied for a PAT engineer role , if you have any tips or more videos using Apollo 600
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?
experience will mainly guide you on this. There isn't much these days that you can't test at 500v. Mainly valve amps and RCDs I test at 250v DC
@@caterhampattesting thanks
MOV metal oxide varister powee boards need to be tested at 250v otherwise they will fail
Love you vids so informative thank you
Thank you, I do try :) I can't confess to everything being 100% accurate as everyone's opinion differs.
Thankyou for the video.. Am I right in thinking that any reading less than 20megs would be a fail, or is there another threshold to use.. Thank you.
Presuming you mean on an IR test? The thresholds are 2 and 1 meg ohm depending on the type of test
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
no that is correct. your pat test machine won't power up the unit when conducting a class 2 insulation resistance test.
@@caterhampattesting thanks for reply

Hi Kim, no probably not unless there were any exposed metal parts on show.

On the Apollo in the video it shows the test type as Insulation only, would it not show touch current or substitute leakage?
you would only need to do touch current test if the insulation test failed. touch current isn't a mandatory test.

which mate are you referring to?
@@caterhampattesting 2:04
what about earth cloaks or braided earth wraps....
In what respect?
I like to use my insulation cloak whenever i can on a class 2
no need to use one of those, keep it simple, and use your test probe on an exposed piece of metal
Hey on class 2 charger if there is no metal parts can you use probe on the actual charging pins. I'm doing 500v insulation test
no this would be visual only. please see my video on laptop / phone chargers
@@caterhampattesting will do
Yes, you would test to the charging pins to confirm live supply conducters and pins are electrically isolated
30 second video crammed into 8 minutes.
glad you enjoyed it :)
