In order to segregate the energy used by different services, such
as lighting and power, you can either use two boards which each
have separate meters or you might consider using a lighting and
power metered board.
Saving energy
Conservation of power cannot just be about measurement. It is
also about using efficient systems and controls.
Timers and photocells help ensure that energy is
used efficiently. More sophisticated control such as
knx/tebis bus based systems also offer solutions.
Such controls are often DIN rail mounted so provision of
extension boxes provides a neat and functional purpose.
