600 watt discharge lighting and contactors

[shane]

HELLO This is my first post on here and i have a daft question .I have a125amp 3 phase 4 wire 415v/50hz supply from a diesel gennerator 105kva.the customer wants 12- 600watt discharge lights installing with a timer to do the switching,i've done all the cable, powerfactor and discrimination calcs and i have desided to wire them in 2.5mm2 swa to an adaptable box then from the box to the lights in 1.5mm2 not swa,,in 3 rows of 4 using and a bank of 3-2 module contactors ct no(2 POLE 230V) and a timer to do switching.i have 3- 2 module merlin gerin ct no 20 amp in the van here and now,
can i mount them straight in the 3 phase distribution board or should i get a modular enclosure and feed them from a 3 phase type c breaker in the distribution board.
any advice and comments please are welcomed.
