Hi all, and what a great forum this is. We're doing up our 2.3 x 1.8 metre bathroom, and from reading various posts on here, this is what I think I'm doing:
1. Replace exisiting ceiling rose with a 4-terminal 5A junction box.
2. From this, run 1.5 mm cables to 4 separate 60VA transformers, which are in turn connected to 4 x 50W ELV halogen downlights, rated IP65.
3. In the loft, construct little boxes out of plasterboard to go round the lights.
4. Replace the lightswitch on the landing outside the bathroom with a dimmer switch.
My questions:
1. Should I a) run the 1.5mm cable from the JB to each transformer, or b) run cable from the JB to the nearest transformer, and from that transformer to the next transformer, etc?
2. When connecting the 1.5mm cable to the transformers, do I need JBs or will choc boxes be OK? In either case, I presume they should be fixed to joists or battens between joists?
3. The loft has chipboard T & G flooring - will the downlights get too hot if that flooring is replaced over them? How else could I allow airflow around the lights?
4. Would a 250W dimmer switch be man enough for the job, or should I get a 400W dimmer?
Sorry for all the questions, but hey, that's what a forum is for, right?
TIA
