You need an FCU for the micro. Cut the plug off the flex and connect this to the load side of the FCU. When you say a 45A switch do you mean a Circuit Breaker or just a DP switch? If it's just a switch, then what is protecting this circuit at the CU? If you do mean a breaker, then a 45A...

:oops: I didn't mean buried underground, sorry, I should have been clearer. (Edited OP to clarify)

IEC60332-3 cable has a copper foil around the conductors, with a stranded drain wire running through it in contact with the foil. With the drain wire earthed, could this be used for runs buried in a plastered wall less than 50mm from the surface without RCD protection?

NO. :shock: That's the problem with a broken ring. 2.5mm twin & earth is not rated to 32A. When a ring is installed, it is deemed sufficient for the cable to be rated to carry 20A (2.5 T&E buried in an insulated wall is rated to 20A, 23A in conduit on the surface and 27A clipped direct on...

Brackers, I don't post here much, but I feel moved to do so after reading your thread. Going on the information you've provided, your installation is EXTREMELY dangerous! On a TT installation (earth rod) the Earth Fault Loop Impedance is relatively high compared to a TN system. If we say...

Give it a rest, Martin. I've not copied and pasted yet because I have better things to do then spend hours on end fighting poxy little wars on internet forums. I came to this forum to gain knowledge and advice before embarking on a major renovation project, but although there are some...

So Martin; were you joking about a man dying? Or were you seriously attempting to blame someone on this forum for the death you had perceived? I'm not trying to be clever or trick you in to anything, I just really want to know what you meant by that particular post.

That is nonsense. I have spent a lot of time reading through the archives here, and you are having a giraffe when you say that. People, who sound perfectly competent to do simple work in their own homes, are routinely insulted, belittled, patronised and part-peed-to-death for wishing to do...

In just how much of a rush must you be, in order for these to be a benefit?

This is the beauty of part-p; if you'd have just slammed the new fan in place of the old fan, you'd be no less safe and quite happy. However, because you have tried to do the right thing you now have to pay a small fortune to someone who has done the necessary courses and paid their money to a...

Right, something sounds very wrong here! You need to find out if this cable does actually go to next door, and if so exactly where it goes. I have never even heard of anything like this. Are you good pals with your neighbours, so you could have a mooch through their house to see where this...

So Martin, the comments you are refering to (as of happening before), were they meant to be 'fun'?

Fair one, I hadn't taken the 3% limit for lighting circuits in to account. At least it gives you something to feel smug about though.

What exactly are you trying to do/achieve here? If you are installing new SWA and a new RCBO, then size both accordingly. If you are trying to use the current SWA and install a new RCBO suitable for it, then 20A is your limit (assuming 4mm^2 cable). You absolutely cannot install a...

You really need to ascertain the size of the SWA cable before you decide upon anything. It should say on the PVC sheath covering the SWA, if not measure the diameter of one of the conductors, half it to get the radius, then do radius multiplied by radius multiplied by 3.14 (pi r squared!)...

erm, to be fair, he did say Am I right in saying that an extraneous conductive part is something metal that comes in to the premises from outside the equipotential zone (ie a water supply pipe) and thus may not be at the same potential as the MET. But an extraneous conductive part is NOT...

The sink is (probably) live due to the lack of an incoming earth. There will always be a small amount of earth leakage (especially from electronic items like computers), but on an earthed installation this (small amount) of current is conducted away, and anything that is bonded to earth remains...

As the others have said, it sounds like you have significant earth leakage somewhere, and the laptop PSU (which leaks to earth under normal operations) is pushing it over the tripping threshold. It could be a faulty appliance somewhere (typically something watery) of a breakdown in insulation...

Happy new year! My comment was not about someone dying and forum posters being prosecuted; so no grip obtaining is required here.

No sleeving on CPC? L+N conductors exposed? Not connected to anything? Penny not bonded?
