Victorian style Garden lamp mains connection query

[60BOWENS]

Hi
We had recently bought a replacement Victorian Style Mains Lamp(old one broke when a small tree fell on it).
Instruction manual's electrical connection diagram is very dark and difficult to make out.
But it has an Earth wire coming from top of the unit and there is another earth wire attached to a screw in the base of the unit.
Feeding wire comes from underground and has got a Live+Neutral+Earth wires.
It looks like a simple Live to Live/Neutral to Neutral/Earth to Earth connection is all it needs.But the circuit trips when I do it.
Not sure how the earth wire at base needs to be connected.
Please help

Disconnect it and put the ends in an insulated terminal block.
Does the circuit still trip?
If yes then you have a wiring fault. If it doesn't trip then the light is faulty.
Where did you buy it, was it new?

I would be looking for a fault with the lamp. Pictures always help.

Pictures would help.

one earth proberly goes direct to the lampholder or top of unit, then a second supplementary earth goes to the main post body, both would connect together with your supply earth, usually coloured green/yellow

Thats what I did-connected earth from the lamp and earth from the body(base) to supply earth.Lamp comes on for few seconds and then fuse trips.

If the breaker does not trip when the light is not connected then there is either something wrong with the light or something wrong with they way you have connected it.

If it does trip with the light not wired in then there's something wrong with the cable to the light.

What sort of cable is it?

Does it run underground?

Did you buy the light from a Chinese seller on eBay or Amazon with the main criterion being price?

Hi
here are some pictures,if that helps.
I must admit it was bought off Amazon but it is IP44 and CE marked
A and B shows how i connected it,but it trips the fuse.C with the earth wire from the base loose,but it trips as well
AA is the wiring diagram I made of how wires lay.
Please advice as to how to connect them properly.

Have you removed cover off circular junction box? Maybe something strange happening in there. Turn power off at circuit breaker first as may be a loose wire somewhere.

I have taken out the wires out from the junction box and the ends are now seen outside connected

The light fittings connector block is supposed to be in the black plastic enclosure inside the base of the light, a short length of suitable flexible cable should then have been used to connect into the round junction box with a suitable gland, or that rubber grommet that is now on the floor. The internal wiring on that light fitting looks rather long considering how far up the fitting the lights connector was. Has the lights internal wiring been pulled to try to make it reach the round junction box, possibly disturbing the connections to the lamp holder, or damaging the insulation?

Is it an MCB that is tripping or an RCD?

Maybe it's best to go back to basics and disconnect all wiring from the underground supply so the cable is not attached to the wires in the grey JB anymore. Make the supply safe.

If tripping still occurs, it is a fault with the supply. If not, as Ban says, there is a problem with the fitting (or possibly the grey junction box between the supply cable and the fitting.

okay,will re-do the connections once more.
Coming to my initial query-the earth wires from the top of the lamp and the earth wire from the base(body) where do I need to connect them.
Shall I go ahead and re-do connections like this pic??
