Any PAT testers on here?
Discussion
Hi Guys,
Being 'assistant' landlord for a property I have taken it upon myself to carry out the PAT testing.
Have a machine, have undergone the required training, all good there,
Went to the flat at PAT tested the devices we are responsible for, kettle failed ... no problem, we'll just replace it.
Out of interest, I tested my sisters kettle - failed on earth continuity, same as at the flat.
Limit is 0.1 ohms, even allowing for a short mains lead, we are miles, out, getting a reading of 0.5 ohms.
OK, so I tested my kettle at home, failed .... same issue.
Tested the base alone, that was ok, 0.02 ohm, tested with a multimeter and got 0.03 ohm, so close enough - my PAT tester is calibrated, so should be giving an accurate result. However, when the kettle is on the base, and testing with the probe in contact with the metal bottom of the kettle, I'm getting about 0.6ohm.
Tested my friends kettle, again failed - same issue - when on the base, getting about 0.6 ohm.
No problem with other devices, tested toasters, m/waves, hobs, fridge and washing machine - all passed with no issues. It's just kettles - no scale in any of them, so it's not that.
Any ideas .....

You'll never get as good an earth connection via the contacts on the base as they just don't have enough contact force. If they did it would be too difficult to lift the kettle off the base. The only answer is the old style kettle with a three pin kettle plug & socket, but people don't like those these days.
Thanks guys.
The kettles all dropped onto a base.
2 in fact were the exact same model, one of those bases failed the other didn’t. Both of those failed with the kettle on the base. Mine is actually quite new, only a few months old.
I have a clamp lead, but was using the standard none clamp lead, pressed against the bottom of the kettle.
Guess this is just one of those times you have to make a judgement call.
