Out of curiosity I have just been browsing small CUs. I thought that 17th ed required RCDs to be fitted but when looking at 4 or 5 way CUs there appears to be no provision, eg: http://www.screwfix.com/p/wylex-5-way-fully-insulated-main-switch-consumer-unit/24223...

It's often healthy There is a stop cock on the water just above the entry point in the flat. Seems the most logical. The gas pipe is not bonded in the flat but is at the meter on the groundfloor. It won't need an extra one.. ?

So it seems that in 1973 builders were hiring some dodgy contractors. Doesn't surprise me.

No. So I suspect the answer is yes. And as I intend to let the flat, someone will probably tell me a new CU is pretty much obligatory. Whereas RCDs required a technical development, there was nothing to stop a lack of bonding from being connected to casualties and from being specified much...

Having read many threads about bonding I am still confused. The question is, when did all this stuff come in? The reason I ask is because I now have my 4th property. House #1, built 1947 - rubber wires in steel conduit, steel bath, no bonding to gas or water, no equipotentials. I rewired...

After my son moved into his house he noticed a strange problem. For some reason, the heating would not come on. A bit of fiddling with the override buttons on the programmer revealed that there was nothing wrong with the system. It turned out (through trial & error) that the programmer has a...

...but the plumber's error is completely irrelevant to the matter of following electrical regs. Please keep it in context. It's probably quite difficult to make something that's potentially or actually dangerous - until a plumber puts a saw through it. Didn't the fuse trip?

As a further thought, it sounds as though the boiler is working - it is turning itself off when the water is hot. If the request for heat is not going away when expected (both CH & HW are turned down), then a thermostat may be stuck. To turn the boiler off, do so at the programmer or turn...

It is putting more heat into the water than can be dissipated at the radiators, so it modulates by cutting in and out. The Solo is not good at cycle control so it constantly clunks on and off. Without turning my system back on I don't remember the light behaviour. The pump is meant to run...

Excuse me, but please explain how an anecdote about physical damage relates to installed deficiencies. But were the fuses/trips not blown?

I didn't know kitchens and utility rooms were treated differently. Does make the regs look a bit smelly. 300mm isn't it? I've never seen an example of a refit done since '05.

Well I do have a stock of red & black cable... Being uncertain... does not mean it cannot be done safely. Two completely different issues.

No, it is a genuine question. I don't blame the respondant for the answer. What's so special about a kitchen? The rules allow for sockets to be scattered around the worktop that are in easy reach of the sink. It's probably considered unsafe to use a toaster near a steel sink. Is safety...

The thing is, electricity is easy. Mains electricity requires respect and care, certainly, but there is a big difference between abiding by the letter of the rules and an installation that is so incompetent it is a physical danger. (It's probably quite difficult to make something that's...

On a slightly related note. In the bathroom, the light switch was originally outside the door. I pulled the cable up and shortened it to fit a cord operated switch inside the bathroom. There is no cable (either dead or live) left in the old switch box so just plastered over it. What would the...

I wondered whether there was some curious rule about feeding a cable through a hole in a stud timber. Pertinent to the "Should Part P be scrapped?" thread. What a totally stupid piece of bureaucracy.

Do the regs allow this? The kitchen light switch is in an inconvenient position, shown as x in http://tinyurl.com/74bz268 and it would be nice to move it by about a foot to y. It is annoying to reach round from the door and as the fridge goes in this corner it has to be spaced away from...

This would be an obvious short circuit which a diyer with a cheap multimeter could find just as easily as someone with an expensive IR tester. I have yet to be convinced that domestic electrical installation is a particular "art" that can produce faults which inhabit some murky grey zone...

Of course it is possible to break a connection... but whenever I have changed socket covers it has always been obvious that a conductor is at breaking point. Even so, I doubt that in these days of central heating, most rings that do not serve the kitchen ever get loaded close to capacity so...
