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.
 
Were the AC-DC power supplies purchased as seperate items or were they supplied asan integral component of the light sets? Where are the power supplies mounted? What's your take on the cause of them burning? Are they overheating or could there be a condensation problem? Have you got any photos you can attach to give usa better idea of the installation?
 
Hi there,

The AC to DC power supplies came as part of the lights, the power supplies are mounted 2.25m from ground on the the tree trunks, I reckon there is an overheating problem which is coming from AC/DC inverter causing it to burn up and short out. There is no condensation involved here but they are outside and are subject to outdoor elements eg. Water. The fittings are ip44 so shouldn't be a problem

See below a photo of a connector which had burned out. This is the only photo I have at the moment, can put some more up tomorrow.
