NoTe:
Measurement Category l is for measurements performed on circuits not directly connected to mains. Examples include: Measurements on battery
powered equipment and specially protected (internal) mains-derived circuits.
Measurement Category ll is for measurements on circuits directly connected to the low voltage installation. Examples include: Household appliances,
portable tools and similar equipment.
Measurement Category lll is for measurements performed in the building installation. Examples include measurements on distribution boards,
junction boxes, socket-outlets and wiring and cables in the fixed installation.
Measurement Category lV is for measurements performed at the source of the low-voltage installation. Examples include measurements on primary
overcurrent protection devices and electricity meters.
