Measurement
Category
Application
I
Measurements on circuits not directly connected
to mains. Examples include: Measurements on
battery powered equipment and specially protected
(internal) mains-derived circuits.
II
Measurements on circuits directly connected to the
low voltage installation. Examples include:
Household appliances, portable tools and similar
equipment.
III
Measurements performed in the building
installation. Examples include measurements on
distribution boards, junction boxes, socket-outlets
and wiring and cables in the fixed installation.
IV
Measurements performed at the source of the low-
voltage installation. Examples include measure-
ments on primary overcurrent protection devices
and electricity Instruments
