It is a bit of VIR cable on the side of an old farm building. It goes through a hole in the side of the building just above the picture and is cut off just below the pic. Don't know if it is fed from inside or what and whether it was live (highly doubt it) :shock: All the insulation has...

The transformer is earthed on the HV and LV side. However, there could still be a small amount of voltage present in the event of a fault somewhere on the LV network

Oh FGS!! :shock: :x

Ahh... the good old meter man didn't double check the screws for tightness!! naughty naughty! Pretty common like they said

Right, drawn a little diagram of how it works. It shows how the power gets from the national grid (the gert big metal pylons) to your house.

It seems as the human race continues to evolve, common sense lessens :(

Might not be anything to do with this at all but... Are any of your neighbours having problems? Service joint on the mains electric cable feeding your house breaking down maybe? Just a thought

It has definately made contact to earth/neutral at the side somewhere.

I work for the DNO as a cable jointer and there are plenty of ancient cables about. The oldest I've worked on was a bit of .25 PILSTA from 1949 and even at that age it was like new inside

That's what I thought, I was just up in the loft the other day and saw the junction box and thought the cable was a bit thick as wasn't t+e, so i isolated the circuit and had a look, decided to replace it. Also, while Mr Bodger was at it, he thoughtfully decided to disconnect the CPC for the t+e...

This cable was feeding the light in my hall, it was going from a junction box on the lighting circuit upstairs to the ceiling rose of the landing hall light. My house was obviously owned by a bodger before :D. The cable is 5 core flex, I think it's 2.5mm2. At both ends (junction box, ceiling...

The lights are 'tapped' onto the circuit so i suppose if you look at a circuit diagram of a parallel circuit, if one of the bulbs in that circuit blows, the others still light and the live (pos/neg) and neutral are still there regardless

Because the neutral and live in the circuit are continuous and the live is switched separately to each fitting allowing independant operation. I suck at explaning things http://www.diynot.com/wiki/electrics:lighting:single_way_lighting :D [/url]

I discovered today that in my house the hall light is fed with a bit of 2.5mm 4 core flex with the blue core snipped off at both ends! Well good! And the screws in the junction box it goes too were loose! Oh well I suppose It gives me something to do tomorrow :shock:

tis a bit rusty! :shock:

Our company are trialing those auto devices at the moment, they have a remote control and aren't too bad. Otherwise you have to firmly put the fuse in place and hold it while its shaking about and sparking until the fuse blows :shock: . They can get into a bit of a state and the scenario...

It will have 3 phases in there. It has a 300kva transformer behind it and the fuse holders have got 315A (IIRC) fuses in them. The fuse holders can have 630A fuses in them if the circumstances allow

That is bang out of order! Literally! :D :shock: Hecking amateurs that could of killed someone! Report them immediately!

Thought some of you would like to see the inside of one of these, they are very common on the LV underground network. Exposed busbars, an ammeter per phase, voltmeter. cables are- 2x .2 PILSTA, 1x .1 PILSTA, 3x .2 Solidall PILSTA and 1x .1 PILSTA Neutral solidal from the tx. We were trying to...
