Yes they were, I remember them.

Some of the old MK ones had 4 lugs for horizontal mounting and two lugs for verticalmounting. Six lugs for the price of two - bargain!

Yup - not as the manufacturer intended but I wonder if they now include the instruction. If mounting in a bedroom then place on ceiling above headboard and fix in place with double sided tape if intended for use without batteries .

You might. have a chance providing it`s not stuck up onto the ceiling paper using double sided tape as the only fixing - yes I have discovered such a thing. I did hear tell of an instance of a smoke detector waking someone up thanks to being installed by that method - apparently there was a...

Back to the OP. If you had bonding but cpc not connected you would usually still have an effective "c.p.c (earthwire)" in effect. Example - you have 6.0 or 10.0 mm bonding to the pipework at or near the appliance etc in question - say immersion heater pipework for instance then the immersion...

That "Hot Leg" method of wiring a secondary Eric? seems as strange to me but there again the Americans (The USA branch at least) seems to sometimes have some strange ideas anyway.

Clockwise/AntiClockwise (or Counter Clockwise ) are becomming uncommon sayings these days of digital time pieces!

It is often said that "Bonding and Earthing are two different things" Well YES but then NO. (sounds like Little Britain?). Earthing (Circuit Protective Conductors a.k.a C P C) is in place to connect metal bodies of electrical appliances etc to "Earth" (our installation MET = Main Earthing...

Maybe its a local term thingy , in fact most electricians of a certain age are exponents of the art of using mini trunking lid for feed cables under floorboards from well before Super rod etc was invented. We used to have a motto :- We the unwilling, attempt the impossibe for the ungratefull...

I must admit that I had never heard of a "Wavin" so I looked it up with google :- The term "Wavin" has a couple of meanings: In slang, it refers to showing off or flaunting one's wealth or status, often associated with young people fastslang.com. In Irish slang, it is used to refer to a penis...

99.99% wherever you put it then it will be a compromise or three!

No it’s not the high load. It is the high number of A/ the number of arcs generated. And B/ the number of wear and tear on the moving parts. A good quality isolator switch will reduce the ill effects of these and will increase the life expectancy of of such. Whatever the switch is fastened to...

Personally I always like there to be an isolator switch preferably immediately outside the bathroom - I’m not keen on pull switches of that type, they require a good pull and on some I’ve seen you might pull the ceiling down or loosen it before the switch pulls to off. I do not advocate using...

Please explain what you mean can’t spur from spur from twice. If you mean two radials (spur) from say one point (or one junction box) on the ring and each of those radials runs to a single socket ( or an FCU ) then no. It used to be allowed because it would 2 x 13A fuses but it was discovered...

Well to stick to the rules you only spur unfused once from any point on the ring - you are allowed to spur to one twin/single socket/Fused Connection Unit although in reality two single sockets or two FCUs are electrically no different from a twin socket because in each case a maximum of two 13A...

Indeed - the measurements give a guide to the "parish" that might might be your first guessthen the other considerations come in to play, then one or two more probably - such as whats in the alcoves, are there shelves and if so are the glass or solid and like wood and is possible to have wall...

The answer is, what do you consider would look best and in practice illuminate best and be the easiest (or not too difficult ) to be best , you might well get three conflictions and you might have to consider the best over all compromise . The final choice is what suits you unless you favour...

May I just add to that? The short stub of wire on the left hand side to be bent over to help it not fall looser in a downwards direction - I know it will need to have slackend a bit in order to fall dowards in the first place and 10.0 or 16.0 earthwire would not fall out but smaller sizes might...

Yes, with pure DC it does not really (usually) matter if only the negative or only the positive is switched and the opposite pole (+ve or -ve) is always directly connected. In fact if you deem that electricity flows because electrons are deemed to flow then it actually flows from negative to...

ADE, I remember when they first became known to Alarm Installers and I was a little sceptic I must admit. The reason for that is (rightly or wrongly) I viewed them as more of a yesterdays technolgy sort of idea with more use of transitors in their circuits - simple but tried and tested. Don`t...
