So, it seems that trunking isn't belt and braces after all. If I'm going striaght on with the plaster, how deep do I need to go? Just into the plaster or do I need to start hacking away at breeze block?

So, leading on from my earlier question where I learned that I can't use the cavity between breeze block and brickwork, I'm now going to chase them into the plasterboard. I've got four lengths of 2.5mm T&E which should happily fit in the 150 mm vertical safe zone where the two exterior walls...

On closer inspection, the cable to the consumer unit passes through the block, void and brick to the unit in the porch. I guess this is where a little common sense is applied as there's no real alternative. The unit is at such a height that some go off through the floor space between levels...

Thanks for the reply. I'm always willing to learn about such things. I can understand how this might happen but how come the same doesn't happen with the foam that's filling the cavity? Isn't running a cable in the void the same method as the cables use to get from the consumer unit to the...

My exterior walls are the common plaster on breeze block, then a void and then brickwork exterior. My question is, do I have to recess into the plaster or can I go through the breeze block, up the void and back through the breeze block in the loft? I know it sounds like more work but I really...

Hi, Just wondering if anyone would like to offer any thoughts on my situation. We've had our boiler moved up into the loft. The old boiler and water meter have been removed. The new boiler is supplied by the old water heater radial which is only 2.5mm. Now for the 5 Amps needed for the...

As the cable goes up through the old cupboard, it has a 13 Amp fuse, this then leads to the boiler and has another fuse, 5 Amp this time. I was thinking of adding a socket between these two fuses just in case I need power up there. The business with the extractor fan is that it currently...

makes perfect sense when you put it like that. I guess my plan was a little ambitious. Maybe I should just run the three items off a radial line. Thanks.

If the ring should close at the same place in the consumer unit, does it have to go all the way back to the consumer unti to terminate or can it joint back anywhere so long as all the sockets are inside the loop? I'm asking as we had a new boiler fitted and the power is supplied of the old...
