There's a B16 RCBO ( a 16A breaker combined with a 30mA RCD) here that does the same thing. I've never stopped to investigate it as it forms a temporary supply which will go soon. The only load on it is a 3.3kVA 110V transformer. I don't think I've ever known it trip when switching off using the...

Is somebody looking for a surface mount oven?

That composition is identical to Multicores surface mount solder. John, check out 'Flux pens' that are for surface mount work. These should be a compatible flux and you maybe able to re-moisten the solder paste.

From what I read Copper is also very 'green' for the same reasons, most of the copper piping sold in the UK is recycled apparently.

If you have an anorak, put it on now! :lol: No, you're not sad. It's good to come across somebody who's interested in what's going on. I'm not a plumber either, i'm an electronics engineer. Although I do all of my own plumbing. And a few other select plumbing jobs as specials. Being in...

Firstly thankyou for a decent and very descriptive post! Once the inlet of the overflow pipe is fully covered with water the siphon should start, if the pipe run is good. The fact that you have to raise the water past this, and submerge it more, suggests that the pipe run is not all it seems...

While a house or hot water tank is kept warm/hot it has a heat loss. The higher the temperature difference between 'it' and the surroundings the more heat it loses. If it isn't heated there's no heat loss. So it can be a trade-off between efficiency and convenience. As the Ideal Isar (from a...

I don't think she will be and I'd be interested to know if the same landlord has other properties. Unfortunately many tenants don't realise what the 'going rate' should be, which is a shame as it would force some landlords to up their game. Then you get to letting agents. They'll be some that...

I'm not a gas engineer but.... I would also guess that the boiler is an open flued type, ie it draws its air to burn from the room it is in. In which case it should have unobstructable vents of a certain size direct to the outside world and ideally one at high and one low level. Although many...

And even if you do get a copy, with something like that don't stop there, follow it up.

I think I'm correct in saying that you can officially use lead based solder for repair of existing equipment but not for new manufacturing, that has to be RoHS compliant. Unless its military and then it's probably exempt from most things, including the CE mark and EMC regs. :lol: I agree...

I'm allergic to the flux fumes having been soldering since I was about 7. I used the 'little pipe on the soldering iron' once and quickly found that they were hopeless. Mind you, my allergy to the fumes by that stage was very acute. So in the end I installed a centrifugal fan in one of the...

Sounds like it would a be good idea for her to go and buy a Carbon Monoxide detector due to the aged, and what sounds to be a system that works but hasn' t been cared for. Also get her to read up about the symptoms of Carbon Moxide poisoning and what to do if and when the alarm goes off.

It comes a a bit of a surprise to me that washers and piping can react with the amount of Chlorine in tap water. Chlorine is a powerful oxidizing agent but from what I know of how Chlorine is dosed into the water supply it's done in a way that means that very little free chlorine remains by the...

If its been in the loft for a while the potentially large temperature variations may have accelerated deterioration of things like the rubber on the pinch rollers and also of the tapes themselves. At a guess its probably chucking the tape back out as the tension is all messed up and it takes...

Very true. I was thinking of my much missed old Servis 600, one of the first push button digital machines c1982 that had a hot fill and used a respectable amount of water to do the job. I refuse to acknowledge its replacement as a worthy replacement due to the puddle of water it insists on...

Too right! Everybody is harping on about being green, many people now have solar water with mixer valves on but can only buy a washing machine that's cold fill only!! :shock: I have a feeling that Miele still do hot fill but while the quality is good so is the price.

I've not really messed with HDMI connections having been knee deep in other stuff since SCART was the best thing around. But some food for thought. 1)The audio and video connections need to be in their own channel/conduit for physical isolation from the mains cable. 2) read up on HDMI cable...

Its worthwhile checking out what standing charge you're on these days and, if you have the bills, looking at what it was maybe 1 or 2 years back. A friend was wondering why, when her elecy usage hadn't really changed and if anything should of gone down, her bill had risen. A look at her bills...

Definitely SWA. Not only will it be easier to deal with rather than mess with routing cable down conduit, it may also be cheaper too overall. SWA glands terminate very nicely in metal enclosures too, to give a robust solution.
