I am trying to install a new metal 4 halogen light unit in my bedroom ceiling. The instructions suggest I wire the appropriate cables coming from the ceiling to the new light via a supplied 3-way box. Unfortunately there is no earth coming from the ceiling (only a live and neutral). Is the 'EARTH' really needed? If I wire it up with no earth could the metal casing become live??

no live it wont work, and yes itting could become liv, try serching the forums, been asked before
rwgb said:
Surely this is a windup. The live is not needed if you get a solar panel to produce 230V and send it to the light via a remote control.
Have a closer look - it is possible that some previous miscreant has just cut it back, and that if there's some slack cable you could strip some more sheath and get access to it. Then, of course, you'd need to check that it was actually connected to earth...rwgb said:
If you don't connect the live you need no longer worry about the lack of earth...

you have to bear in mind this is a diy forum, some people have no idea what so ever, then again he may have typed EARTH but spelt it L I V E
pdcelec, its a good theory, what size remote was you thinking of?
I was attempting to make the wording as clear as possible and go and make a howler like that, sorry for the confusion.
On a serious note though, there is no cable stripped back or hiding behind the ceiling.
However, the bracket supporting the new fitting is screwed into the joist - would this not earth the new fitting??

I suppose if the wood was conductive enough and a cable run from the joist to the cu then it might
OK - simple summary
1) If your lighting circuit has no earth, then you cannot use any light fittings that require one.
2) If your lighting circuit has no earth, then you cannot use any metal light switches or dimmers.
3) If your lighting circuit has no earth, then it might be old, and it might be an idea to have the whole of your installation checked by an electrician.

Is it not possible that it's an RSJ?
If it was an RSJ then it would also need a main bond.

I'm thinking of running a fan heater in my bathroom. However, the floor has just been tiled, and I cannot run any cables to the required spot. But there is a Hot & Cold feed nearby for the basin.
Can I wire up the pipes to the mains outside the bathroom, and tap off them inside the bathroom for the heater? I guess logic tells me I should wire the HOT pipe to Live and the Cold to Neutral.
Then I can pick up an earth off the studwork. Is this OK, Ban?
