I hope it's OK to post a request for help on an outside problem,
it's on electrics not plants.
We have a garden lighting circuit, looks as though it was professionally
installed, but could be at least 20 years old.
It has an earth leakage CB.
The CB is tripping out all the time so obviously there is a fault.
Have checked what I can see of the cable and it is two core, red and
black. No sign of an earth wire, although the sockets have an earth wire
in them, it doesn't seem to connect to the cable, just to the joint box
on each post in the garden.
All the sockets are round pin and I was thinking of changing them all
for square pin, hoping at the same time to cure the tripping out.
Could the tripping be due to simple condensation in the old sockets, or
is there any way to check to see if the cable itself is faulty. ( if its
the cable then we will abandon it as it would be a megga job to replace
Any ideas or advice please. Is it normal to have such a circuit without
an earth wire?
Thanks in advance
