There are a couple of construction differences which may be present, depending on the style of “lighting control panel”. <\/p>\n

First, a distribution board typically has poly-phase branch breakers with the intention of feeding either other sub-panels or large loads — such as a motor with a motor controller<\/a>. <\/p>\n

A lighting control panel will have mostly single-pole breakers with phase-to-neutral branch circuits feeding lighting circuitry. There is the added possibility of having either ‘smart’ breakers or integral contactors included on the branch circuits to allow for a control means for area lighting beyond local control of an individual fixture\/small group of fixtures, such as an office or conference room.<\/p>\n

In general
\n1. The final branch circuits to be identified and rating load to be estimated.
\n2. Adequate utilization\/diversity Factor to be applied if applicable (depends on the application).
\n3. To ensure the load balance over the 3 Phase as possible.
\n4. For Fluorescent light fixtures arrangement of the said fixtures with respect (RYB phases) is necessary to mitigate rendering\/glaring and frequency affect.
\n5. Then size of cable from DB to LCP can be determined\/sized, rating of the protective devices can be selected and type of CB(s) subject to type of lighting fixtures.
\n6. Verification of Voltage drop within the prescribed limit, otherwise select the next standard cable size.<\/p>\n
