I say it was a screw as i looked like there had been one there it had been put in the removed and when we went along the length of cable we found the hole because of the bubbling water coming out of the cable.

A reading of 0.01 mega ohms on the brown cable and the armouring.

Sorry meant dug up the cable and then seperated the ends and did an insulation resistance test to eliminate the good side and faulty side.

There was a mini digger and driver on site.

A friend of mine recently asked me to go to a job he was working on as he had broken his hand and was unable to work. When i arrived i found out that there was a fault on a 100m lenght of SWA, which was buried underground, after speaking to the customer it became apparent that he had fallen out...

I've recently been asked to hang a light fitting that is approaching 9kg in weight, now for most heavy duty light fittings or chandeliers i have used one of these...

That's what i think as well, and i'll probably end up doing option number 3 because option 1 is expensive and even though option 2 would be cheaper for me it will cause to much hassle and mess for the customer. Also option 4 is out of the question because as you said it won't satisfy the customer.

When i rang JCC i finally got through to there tech. line and the person there told me that because i was using 20-60va transformers then the 60va should be multiplied by the amount of lights to see what the maximum load the dimmer is taking, and therefore 60 x 16 = 960 so according to him the...

As i've still not found a resolution to this problem and with the customer wanting it finished and me wanting to get paid, i'm thinking of changing all the lamp holders in the downlights for mains voltage ones. Would this then decrese the amount of buzzing coming from the dimmer?

Well i've been waiting for a call from jcc all day and haven't recieved one yet but as soon as they recommend a dimmer to use i'll change it to that and let you all know.

Sorry yes your right, its from the jcc lighting shop though. So according to that quote if i were to get an IQ dimmer then this should stop the buzzing, because at the moment it is dimming the lights but just buzzing quite loudly.

Right ok thanks well as seen as i have jcc downlights and jcc transformers i've rung the jcc tech helpline and am waiting for a return call.

Sorry ban-all-sheds after reading through your post again i kind of understand it a bit better so what your saying is i should get a dimmer that is recommended to be used with the transformers?

If it is link 3 you are refering to then yes i bought the dimmer.

Sorry yes i did mean ELV, and in answer to your questions yes the transformers are suitable for dimmers and yes the transformers are dimmable but i what do you mean by 'have you matched the leading-edge/trailing-edge characteristics of dimmer and transformers?' And yes i agree it is alot of...
