can we also assume that the cupboard is outside the bathfoom seperated by at least a door? If so are you going to fit the heater in the bathroom drill through a wall and terminate all the cables inside the cupboard outside the bathroom ?

I'm assuming that you are going to use the old immersion cable to feed the heater, or are you running new?

Not quite sure what this test was you were doing between the E/N if you was getting 0 VOLTS between them. that is spot on as you have 0 potential. If you were doing some sort or ring continuity test and testing the loops for Rn and R2 I would expect you to have some sort of resistance...

Let's deal with the 4mm Twin +E you say it's buried in a steel conduit, can you guarantee that it is in steel conduit all the way to the garage?? If I was the Sparks I would not take the chance and want to have a look and see. How far is the Garage from the house. That will govern what cable...

It is frowned upon now to notch or cut joists and noggins as it can weaken them. It is recommended that you drill holes through them to run cables. What you can do is before you fit the insulation run your cables to the positions fit your noggins as I'm assuming as you are running flush and...

[quote="MalcofArabia";p="1704302" Also that 3 core cable that is RED/BLUE/YELLOW could be the old 3 core+ Earth but missing the earth. If you have enough spare strip a little back and see if there is a bare copper wire, which should be connected to the other earths. Not forgetting to sleeve...

Well it certainly looks like that is the correct way it would be wired. A double check would be to remove the switch that controls the light and see if it's yellow in there. Bit concerned about the colouring though. Not sure I've seen RED/BLUE cable outside of control cables. So that's...

Quite right BaS wrong terminology as the red book is not law

Providing that the extra light will not overload the existing circuit or alter the Zs for disconnection times then no problems. But the problem is not the extra light but the procedure to fit it. As it is outside it is classed as a special location and therefore you will either need to...

First that 32 amp breaker protects the cable installed not the appliance as such. So you should have at least a 6mm cable on that 32amp breaker. The new regs came in July 2008 and there were quite a few changes yes. You will need to check you CU to see if your installation was done to the...

Steady as she goes lads :lol: :lol:

Change the tails you can't go wrong really. You could mention for brownie points to the assesor that the existing tails were sufficent as it is just a 60amp supply but in case of further expansion you fitted the new ones. As far as the seals go we all know that every sparks known to man have...

Not sure if this is a bungalow or not but a bit of a run from a kitchen normally on a ground floor to the loft. Also if he developed a fault on the hood would the kitchen lights go out? Nothing like scrambling in the dark in a kitchen. No can't see why you can't come of the cooker supply...

Not sure where your going with that ban.

The poster originally wrote that the installation is spured off the ring final circuit. If he had said that it was spured into a FUSED spur unit then, it may be a little different. Though still not Ideal at leat the 2.5mm cable coming of the ring would have the protection of either a 13amp or...

The only time Part P mentions a shower is in the context of the room which contains one. What Part does say that if your replacing an accessory like for like, i.e a shower, and that there is no need to alter the existing circuit, then you do not need to notify LABC. Now there as always...

I don't think you would have both a exported Earth and a TT System as that don't make sense, but stranger things have happened. You may find that you can drill through the wall your CU is on, providing it's an out side wall and most of the work could be done externally. A good sparks...

Sorry KKen I should also have said that in order to use the exisitng SWA you will need to carry out a small Periodic Inspection Report (PIR) on it and the garage to satisfy that the installation is safe. A Sparks will check and make sure that the cable and everything is safe so this is just...

KKen what you have there is not legal you can not run a garage installation off of ring final circuit spur. You never quoted what size the SWA is or how far it runs. Those pieces of information is vital if your not to dig up the existing cable. If it's 2.5mm then you will need to replace...

This subject of testing is something that as so many sides to it. I know that over in the continent where the use of RCD's have be in place for several years testing was not as in depth as ours is. With the UK now advoacating RCD's and RCBO's will our testing procedures be changed in perhaps...
