Hi All,
I've recently installed LED tree lighting on outside trees at a local shopping centre. There are 27 sets each with a power output of 27 watts each. They have been installed using a ip68 outdoor commando socket and plug to protect against the elements. They are fed from a type b 6 amp breaker and wired on 1 circuit on a 2.5mm hi tuff on a 120 metre run. My calculations were as follows:
Design load:
27 sets
x 27 watts
= 729 watt
/230
= 3.16amp
so by my calculations I think I have everything covered, however here's my problem- from day one these lights have gave me problems with the AC to DC inverters on the lights burning out and going on fire causing the mcb to trip out. Of course the manufacturer is blaming the spark and the spark is blaming the manufacturer and we are getting nowhere. Has anyone any experience with these type lighting installations? Everything electrically is testing out and EFLI and VD has been verified to meet regs. Does anyone know does LED lights have high inrush currents or any special wiring requirements?
The Led tree lights were supplied with a plug with 3amp fuse which was cut off and replaced by a commando plug with no fuse protection. The circuits only protection by by means of 6 amp mcb.
All help welcomed and appreciated.
Thanks in advance.
