derived circuits.
Measurement CAT II applies to protect against transients from
energy-consuming equipment supplied from the fixed installation, such as TVs,
PCs, portable tools, and other household circuits.
Measurement CAT III applies to protect against transients in equipment in
fixed equipment installations, such as distribution panels, feeders and short
branch circuits, and lighting systems in large buildings.
Measurement CAT IV applies to measurements performed at the source of
the low-voltage installation. Examples are electricity meters and
measurements on primary over current protection devices and ripple control
units.
