What to do with the Earth?

[optionclick]

Hi all, hopefully a rather straightforward issue that I'm hoping you can help with.

Over the weekend I was changing a wall-mounted porch (interior) light for ceiling-mounted spots.

The original light was connected with a regular Twin and Earth cable.
The spotlight kit included a transformer box with connections for live and neutral, but not earth.

The installation instructions stated to 'run the earth back on itself' as the kit does not require earthing.

So.... what does this mean? What should I do with the 'spare' earth wire?

To give further detail, the Twin and Earth cable originates from a junction box, which is fed with a Twin cable (no earth). I'm a little hesitant to simply leave the earth unconnected.

Thanks in advance

If there is enough room to terminate it back into a terminal block then do that.
Doesn't sound like it is connected anyway so technically what you have is an open circuit protective conductor which is wrong. Smells of a 1960/70s installation, might be worth having an electrician take a look and see what they say.

You're probably right about the antique wiring!

A re-wire is on the cards, but on hold until funds allow, so this installation should be viewed as temporary, however I still want to make it as safe as possible under the circumstances.

Thanks for the advice

Nothing so permenant as a temporary installation.
