Street lighting

[Aargent27]

Got a street light that keeps blowing the fuse in the cut out.
Single core cable with sheath connected, have disconnected the feed to the lamp and it still pops the fuse.
Any ideas they are the old concrete post type.

Fault on the cable.

The fuse in the column blows? What is still connected to it if not the lamp? Is there a loop out of the fuse to another column?

How can it be the lamp if it is disconnected?

Any testing done other than replacing the fuse to see what happens?

Single core cable?

The right questions are already above.
To start with where is the fuse that blows, within the column or at the supply elsewhere?
I'm familiar with the concrete post types, have about 10 of them on a site I look after.
A photo of the column innards would help a lot too, for example is there a Lucy/Tamlite connection unit in it....
Is it a split-con cable feeding it?

Probably Sox or Son and faulty control ballast/ignitor?
