MCB = Circuit Breaker? CU = Consumer Unit? Whats the difference? I thought the MCB was in the CU?

Yep. Aldi special. I replaced the battery tonight just to be sure.

Don't worry I will be very careful when I am in the CU. Honestly, I don't need that kind of shock. So I'll just check the neg going into the back of the fuse thingy to make sure it is nice and secure. If that is ok can I purchase a tester to check line continuity. I used one of these when I...

Right, I tested for resistance and got a tone so that's a good thing at least,.....assume that means that the element is not burnt. Do wires ever just work themselves loose behind a sealed CU? It just seems odd that with no moving or decorating the Neutral should just fall out...

I'm happy to do it myself, just gonna wait until it's light....so if I kill the main breaker and don't touch the grid wires (tails)....I shouldn't fry?

RCD is in the other half and the blanking plate is on my to do list......only realised myself tonight. Thank you for pointing it out thought :)

This is excellent help!! So regardless of whether the element is burned or not I should still see 240v on all the terminals up to the element? Can you have a look at this picture and tell me where to test for resistance?

Any idea why I am getting a near decent voltage when I test L&E or N&E?

Unless it is hidden under the floor boards I don't think there is one.

If the immersion had actually burnt out all together would this break the circuit? So when I am testing across L&N in this scenario would I see the voltage drop? and on either side L or N it would show the right reading?

Red to red only reads 22v Red to red and black to black reads 0v. Can actually watch the voltage drop on the multimeter once you touch the black.

L&E or N&E are both giving reading >200V...............WTF?

Interestingly, as you can see I have bypassed the switch with that block. When I take a reading (just replaced the battery) with the multimeter, I get 26v with just the positive test lead, when I use the neg test lead the voltage drops off all together.

First things first.......here's the pics. Secondly, from what I can determine, the supply side (before the switch) is directly from the MCB, then the output (don't know the right names sorry) goes up to the loft, through a fused swtch, then to the immersion.

No. Wires are isolated there. All wires are the same size.
