No, I took a look, it's just a conventional one-way switch. So could I just replace the existing switch with a switched FCU? But doesn't that mean that the circuit is still potentially allowing 13A up to the incoming side of the switched FCU? I thought that the FCU had to be on the supply...

I've just discovered that the outside security light (a double spotlight with PIR) at the back of my house has been wired to the upstairs ring main. It's mounted about 12ft up the back wall and is supplied by a cable running off a double socket in the back bedroom, and then out through the wall...

I would use a large stick, but I'd be done for breaching their human rights... I know I know...I'll never get my money back. But just in a technical sense, would it be suitable? Also I thought quite useful if you're emerging from the dining room with a load of washing up and no free hands...

I have a galley-shaped kitchen with a halogen E27 6-spot bar ceiling fitting. Rating 50W each, total 300W.The kitchen does not get much direct light so is usually on when occupied. The light is then often left on (not by me) when unoccupied. I've tried 11W CFL spots but not very impressed with...

Can anyone help on this one please?

Thanks, could I just get clarification on one more point? Are the Wylex RCBO's (part no. NSBS32/1) compatible with my Wylex NS consumer unit as well as the newer NH units? TLC's website says they fit both NH and NS, but when I asked them to confirm this, they said they couldn't tell me and...

Thanks for the various replies...and the MIL jokes, I really should have seen that coming...(BTW ban, neither of your blonde ladies resemble my mother in law, sadly). In reply to the various points raised: Main fuse and board are 100A. The shower fitting instructions (Galaxy Aqua) make no...

I have recently visited my mother in law who has just had a new bathroom fitted. This included a new shower, a Galaxy Aqua 3000 (8.5kw). This takes about 35.5 amps. The original shower was an ancient Triton, probably about 6kw. As far as I can see, the original cable and DP switch have not been...

No, I've been changing them when they show a low battery warning. Typically about a 2 year cycle, but I think the one I just replaced was the original-it's a side door that is rarely used. No signs of battery leakage or corrosion, if that's what you're thinking.

I have a Wickes 710702 wireless alarm system, with 4 PIR's and 3 magnetic door sensors. The control panel was showing a low battery warning. I changed the batteries in one of the door sensors because the little red neon was not coming on when it opened, it's now OK. But I'm still getting low...

Thanks, I'll call them tomorrow. So I run the 16mm earth wire from the main earthing block on the meter board and leave it for them to make the connection? There is already an earth connection from the meter board block to a point just upstream of the service head (can be seen in the pic on the...

Sorry, this time with pic attached. The leak is from the lower unit, looks like used engine oil. [/img]

I've just noticed that I have an oil leak from my service head (see attached picture). I'll call my DNO to get this seen to but is it something that needs urgent attention? And why is the service head filled with oil anyway?

Thanks, so (physically speaking), B and C are interchangeable? I am changing to CFL's, just working my way round as the old ones fail. Going back to my original query about RCBO's, so should I be looking to fit B or C type, given that my existing MCB's are B type?

Thanks for the advice, but I'm not clear on the difference between B type and C type though-please could someone explain this further? All my existing MCB's are (I think) B type, for example, serial no. NSB06 B6 on the lighting circuits. On the subject of MCB's. I read another post which said...

I have a Wylex NS1104 CU which was installed about 9 years ago. If I understand correctly, there is no built-in RCD protection on this model. On that basis, I would like to add some RCD protection on the 4 power circuits (up, down, kitchen, cellar). These currently all seem to have 32A MCB's...

Thanks for that. Yes, it is an ex-local authority property. I have a standard multimeter, can I check the earthing for them, if so what is the procedure please?

I've just replaced an old pendant bathroom light with a new flush-mounted unit for a friend. Ceiling was solid concrete. On removing the old rose I found the following wires inside a metal-lined conduit box recessed within the concrete: 2 black neutrals. 1 earth from cable (probably the...

I've now measured it precisely and the ceiling is 2.33m high (just over the 2.25m limit). And the edge of the fitting is 5cm horizontally from the edge of the shower enclosure if projected up to the ceiling. Looking at the IP diagram, this is technically Zone 3. However common sense tells me...
