mportant Information - Determining the Appliance Class
Before you can check any appliance, you must first
determine the class of the appliance.
This will determine which LEDs you need to check whilst
testing.
Appliances and cables generally only fit into one of two
classes: Class I or Class II.
Class I Appliances
Class I appliances always require an earth wire from the
earth pin of the plug to the bodywork of the appliance for
safety. Examples of class I appliances include:
Kettles, toasters, irons, microwaves, washing machines,
PCs, monitors, shredders & laptop chargers.
Class I Cables
These must always have an earth for safety which runs from
the earth pin of the plug to the earth socket on the earth
socket on the other end of the cable. Examples include:
Kettle power leads, PC mains leads, laptop power supply
cables, monitor mains leads, 4 way extensions & extension
reels.
See cable examples on the following pages.
