Selecting the busbar trunking
Knowing:
p The type of luminaire (types of lamp, power,
compensated or not), their weight, number and
distribution.
p The structure of the premises (option of mounting
busbar trunking).
p External influences (IP degree required).
Reminder of the various stages of selecting the busbar trunking (See the selection and study guides on
page 0120Q-EN.fm/2 and page 0120Q-EN.fm/2 and page 11068-EN.fm/2 to page 11068-EN.fm/11)
p Select the type of busbar trunking depending on the possible fixing distance and/or the weight of the luminaires.
p Select the number of live conductors depending on the distribution scheme chosen or the number of lighting
circuits.
p Select the Inc rating depending on the operating current.
p Select the power supply cable (type and cross-section) depending on the operating current and the type of protection
against overloads.
p Check the voltage drops.
p Select the type of protection against short-circuits and its coordination with the busbar trunking.
Selecting the tap-off units
Tap-off units are always single-phase L + N + PE or 2L + PE.
Their selection depends on the functions required during installation and operation.
