Pat Testing, special case (electronic switch):
It is easy to misinterpret an insulation test on appliances fitted with an electronic switch.
The electronic switch limits the insulation test scope (only testing power cord).
One solution is to use a substitute leakage test at 40V. This allows testing beyond the electronic switch without powering up the appliance. This approach is particularly useful for computer. It does not energise it and no shut down is required.
Another solution is to power up the appliance and use a leakage tester (leakage clamp meter).
I hope you find the above information useful. Please let me know.
