Sparkies have no direct authority to disconnect your power. However, if something is found which is immeadiately dangerous (which would be code C1 on the report) they should make a reasonable attempt to contact the person ordering the work to advise them of the danger (and hopefully the person...

I see its use becoming far more frequent

could be either.

Arcing happens where a switch makes and breaks a circuit. If you have arcing at a light fitting, call a sparky, pronto. Generally, its only a switch that arcs. EICR costs can vary with the type/size of house. Do not bother with a very low price, get 3 quotes and decide. You (hopefully) get...

It might make a subtle difference, but seems a bit pointless. Effectively, Its the current, not the voltage that causes heat/fire. The switch at the wall would still be at 240v and the current would proabably be similar. If you are worried, i might suggest get a spark in to give the place a...

Thats quite probably true. There may be other factors that affect the amount of arcing aswell. e.g. inductive or capacative loads, frequency of switching, contamination of switch contacts, etc...

The zone height stops (as you rightly say) at 2.25m. Where did you get the belief about the 3m bit? There is a significance to bathrooms and a measurement of 3m, but i don't think its applicable in this context.

It sounds like a bonding cable, which although is not live, it is very important. If it is not likely to be damaged in its location, then its ok. Personally, i don't like to see it and prefer to drop that cable through a length of conduit, but thats just cosmetics.

Onslaught? Dear oh dear John, you can be quite the drama queen when you want to be. I thought you enjoyed hypothetic style debate? Thats nothing more than pure conjecture on your part there John. I am in-different to the existence of such a PFC, it may exist, it may not. For those who are...

But have you actually stopped for a moment to read it? Yet i imagine you will Yes, it does. I was just a little curious as to why you are being the way you are. it wasn't but it that is not what you initially typed. ditto. But why are you still posting? it was, but if you have one thing...

John, why don't you go back to the beginning and look closely at what you actually typed instead of what you are now trying to suggest you mean't to say. Your statement implies that you are evaluating Zs. You say that so long as disconnection times are satisfactory, there is nothing more...

Why don't you call your local LABC to discuss the issue, find out if they actually give a monkeys? I'm sure they'll be happy to discuss it at length with you :)

OK. There are many houses spread across this country which are closer than 23m from the supplying sub. The frequency that such houses can be seen will undoubtedly increase proportionally with urban density. That seems very obvious to me, but maybe not so to you.

I'm always playful, it gives me a great sense of well being and an inner warmth. This is the first time you have included the 'i.e. disconnection times' bit. Up until now you seem to have been talking about the only consideration regarding Zs is to ensure dis. times are met, there is nothing...

( I can't really believe I'm having to type this out as it is already written above ) -You said if 'Zs is low enough for disconnection times' then that is 'it', nothing more to consider. -I say it is not 'it', there is more to consider. -I say, you need to consider the potential damage that...

Im sure there are many dwellings spread around the country which have a sub <23m away. Probably more so in urban areas/cities, wouldn't you agree?

oh BTW, almost forgot 10 points for you for getting there. Also, wrt that rather unclear statement which you asked whether i agreed or not. It was just a bit too rumsfeldy for me to really know whether i agree with it or not. Maybe you could rephrase?

That is not what you said. There really isn't any need to erroneously paraphrase that which can be seen above. It is clear what you did say. John, unlike a verbal conversation where it is a bit easier to back track as its easier to fudge (due to the reliance upon the contemporaneous memories...

ok, you say no-one could find a reg (as per your opening quote).... your starter for ten>>>> Taking my response to be true (Ze<0.04 Ohm), then i say reg 133.2 could very easily become a problem in a standard domestic install.
