If they wanted to set up a database so that people could register on an entirely voluntary basis in order to help the police in the event of something happening in the area, that's fine. I absolutely object to the idea that somebody should be forced to register just to have a camera on his own...

Yes, 2A was more commonly used for lighting with 5A for smaller appliances. Although obviously there was nothing to stop anyone using a 2A outlet for suitably low-powered devices like radios, etc. Switched 2A outlets for lighting seemed to make something of a comeback for a while (early...

Indeed, a length of floating pipework running parallel for some distance to a cable could well sit at a significant potential due to capacitive coupling.

Or perhaps they're wrong now. Changes in the wiring regs. don't always make things stricter as is often assumed - Removal of supplementary bonding requirements, increasing the current rating of cables, relaxing the standards for maximum voltage drop, etc. Fair enough, but that will involve a...

That it would result in C3 becoming so widespread that it would lose its impact and it would probably end up being completely ignored by most people, thereby detracting from things for which a C1 or C2 can't be justified but which really could use improving.

That if one is going to say this - - then surely that should go for everything which is not to the current regs? So is it an assessment based upon judgment, or a simple call upon whether something complies with the current regs. in every detail? If the latter, then just about every EICR...

Neither do they say that existing "combustible" consumer units need to be replaced. But they say that newly installed units should be "non combustible" just as they say that new wiring should be brown/blue.

Thin end of the wedge. What would be next - A license for any sort of camera because you might take a picture of somebody in the street? Public places are just that - Public. You have no expectation of privacy in a public place. And it's a bit rich coming from a government which has...

What if part of the installation is brown/blue? As you've pointed out yourself in the past, those responsible for BS7671 obviously consider it to introduce enough of a potential risk to require the addition of a warning notice.

Sure, but the point I was trying to make is that if you're saying that pipework should not be earthed because of the possibility of somebody sustaining a shock by contacting some other live point while also in contact with that pipework, exactly the same argument could be made for not earthing...

Yes, that will be EDF's Option Tempo, which provides for six different rates: Blue, white, and red days with day and night rates (heures pleines & heures creuses respectively for each. Most of the year is the cheapest blue days, with up to 43 white days and 22 red days per year. Here's a...

Yes - It's a common arrangement in living rooms and bedrooms, most often - but not always - the lower half which is switched, sometimes just at a couple of outlets, sometimes at various outlets all around the room. Wall-switch controlled outlets for lamps were quite popular in Britain at one...

But the reasoning for not earthing the pipework in that case could also be used as an argument not to earth the metal casing of a class I appliance. But who goes around deciding or changing bonding arrangements on such unknown things? But they are not metallically contiguous items running all...

So do you C3 red/black T&E because it's not to the latest regulations and want to recommend that it be "improved" by going around adding brown/blue sleeving throughout?

As in Bernard's example. Say you have continuous continuity from the immersion heater tank to the hot tap, which is therefore earthed by way of the feed to the immersion heater, but plastic couplings have left that unbonded cold piping floating, or in reality earthed via the relatively high...

Nearly 2:30 p.m. here at the moment and a beautiful 77 degrees on our patio. :) There might be one or two things I miss about Britain, but the dreary, drawn-out winters aren't one of them!

Even if a fault causes that part to introduce a potential into some particular location which would not otherwise be there?

Indeed, with increased used of plastic couplings, plastic tap fixings etc. there's far more potential (no pun intended) for such things to happen than in the past when there was a good chance that every bit of plumbing throughout the house was all bonded together electrically.

But earlier you said: If you are recommending an improvement of something which may give rise to danger, then surely it would warrant a C2 or C1 coding?

A fault which places a potential on, say, a kitchen tap could in turn introduce that potential to the bathroom plumbing.
