I see the stress of the extradition is getting to you again BAS. :D

I've come across this quite a lot - a door inside a bathroom that leads to another room. Someone told me that the 'other' room is often called a 'hallway' and some (usually downstairs) are often called a 'kitchen', but I'm not sure if they are having me on.

The Fluke is very good. Decent sized jaws, very robust and simple to use. Only niggle is lack of peak hold. Expensive though.

Yeah..right. Since when did the truth ever stand in the way of a good story reported by 'journalists'? Correct if we are talking about stone cathedrals and castles. There aren't many semis and bungalows as we know them in Eastern Europe. Are we still industrialised? You learn something new...

Actually from the Greek Praktikos, then Late Latin Practicus, then medieval Latin forms practicalis, practicare then onto Middle French practiquer. In English as practicable circa 1670 derived from the English practic circa 1475 and as practical before 1425 derived from Middle English practik...

Magic...??? No. They just read the book 'Harmonization - My Part In It's Downfall'. An unpublished work, distributed in secret by the IEE and other 'interested' parties.

I'm not sure to what part of which question you are answering there :? But the retroactive argument is always interesting, in that it is usually rolled out by those who prefer not to think. They take that position with every Reg and every Edition and follow it blindly - even when carrying...

Yet most kit is installed on the (fireproof) backing board installed by the REC. :D The requirement is for the backing material to be non-combustible when tested to BS476 Part 4 or fixed directly to building fabric having the ignitability characteristic P of BS476 Part 5. So is it right...

I don't go along with 'blanket' Code 4s just because something complied with a previous edition. It depends on the deviation and the type and use (and user) of the installation. Heat damage evidence could be 20 (or more) years old, so I wouldn't necessarily give a Code 1 unless there was...

I suspect that when the clerk receives some paperwork in a foreign language, they won't make a decision at all - but escalate the matter and place it in the inexorable machinations of the internal email merry-go-round. Which is when all manner of people will dip their fingers in it before...

I wonder how many people have tried to start a fire with Swedish Fire Steel and a noggin of softwood (let alone hardwood)? Or with coarse shavings? Even though they are fairly recent, I bet there have been a lot more melted modern CUs than burnt out Wylex boards.

A standard which the supplier will either accept or not. I would like to think it would be an issue decided solely by a qualified engineer rather than the in-house or contracted-out legal team. But we don't live in the CIS. :cry:

My concern with this is the mixing and matching of different (national) standards. Either the whole installation conforms to one standard or the other (and that standard should satisy the requirements for a supply to the property). The other problem is maintenance. How likely is it that the...

My copies of BS7671, IEE Guidance Notes, OSG, Approved Doc P etc...and sight of all 1st fix. IEE OSG, IEE Guide to Building Regs, Approved Doc P.

No, that part is covered by the RCD part of the RCBO. It may also be covered by the mcb part of the RCBO, but even if it was, the RCD part of the RCBO would disconnect in 40ms (assuming a fault and not leakage), whereas the mcb side would disconnect in 100ms. The RCD side can not cover...

To which standard or bespoke design does the existing installation comply with? To which standard or bespoke design will the addition comply with? If the answer is BS7671, then the 'design' would be in compliance with BS7671 and the addition would be I&T in accordance with BS7671.

Comply in full with BS7671. Whether or not they do so in reality is neither here nor there, but I can not advise them to not comply in full with BS7671. It's also my opinion that I don't think anyone should advise anyone else to not comply in full with BS7671.

If there is a domestic installation which has been designed and constructed to a bespoke design or other recognised standard, there should be relevant docmentation to attest to this. It would then be a matter for the Inspector to apply this criteria to the addition or alteration (if they comply...

Replacing mcbs with RCBOs requires a degree of care. It's important to either replace a Type B with a Type B, for e.g., or else re-calculate (with direct measurement) the line-neutral impedance to ensure that the mcb part of the RCBO continues to offer overcurrent protection which meets the...

Let me rephrase - If people are incapable of complying with it in full for the work involved, they should leave it (the electrical work) alone altogether. As for the rest, I gave a full reply earlier. The reality is that in the absence of a submitted standard, BS7671 will be assumed to be...
