Laptop Supply and IEC Cables
If you are testing laptop power supply and kettle-type leads,
there is a special adaptor kit which is sold separately which
will allow you to easily test these with the test probe.
110V and 240V Industrial appliances can also be checked
using the adaptor kits.
Special Appliances
There are some appliances which are Class I which you
simply cannot access any metalwork with your test probe.
These are appliances such as laptop power supplies, some
shredders and some makes of desktop fan. There are also
some flat bottom kettles with entirely plastic casing which
come under this type of appliance.
The general rule of thumb is that with these appliances
only you can omit the earth test and treat them as Class II
only on the condition that there is no metalwork that can be
touched with a nger.
