Tight bearings could result in an overload of the motor. At the very least an increase in length of time for which the circuit protection has to handle the starting current. You can't test for tight bearings with any kind of electrical meter. You can't test for an increase in starting time...

Could be wrong but I always thought that the preference for 110V equipment wasn't anything to do with the peak voltage. More to do with the need to use an isolating transformer to step the voltage down. No one uses autotransformers on site right? If the UK was 110V as standard I could see a...

argh sorry... need glasses and a brain I was using the links at the bottom of the forum :(

Most aerials sold nowadays are wideband. It is important to have the elements correctly aligned to the transmitter's polarization. This will be either vertical or horizontal. I haven't looked up which you should be using. This site http://www.megalithia.com/elect/terrain.html is useful...

I'm curious as to how much (as a percentage) the meter is over-reading.

oh joy, every single socket would have to be moved upwards about a foot. every room would need redecorating after the change all the wire would have to be changed as it is the wrong colour. I have a lot of sympathy with the opening poster : there ought to be a simple and not too expensive...

Modern trusses are complex engineering structures designed to use the absolute minimum amount of wood. I doubt that the supports for the tank are over engineered. Builders don't like putting in any excess money (read wood) The purpose of the tank supports is to spread the load uniformly...

So it isn't a special location. Does the 60cm exclusion for zone 2 still apply? It would seems sensible for it to apply but I don't know.

will the addition of a hand basin make notification necessary?

Whilst the heat from a tungsten bulb does make a contribution to space heating. Any arguement based upon that waste heat misses the point that using electricity directly for space heating is a very poor use of probably our best energy source. I am always suspcious of anyone who claims that...

Each of the different lighting technologies has uses. My own experience of CFLs is that whilst they do last longer than tungsten lamps they are unsuitable for intermittent short duration use, the elctronics inside the lamps is often very poor and the construction quality of a lamp can be as...

sssshhh don't anyone mention the mercury inside the CFLs

You could always use a three phase busbar and remove/ignore one of the phases. This does mean that you have to use blanks between the breakers to pad them out. I would cut the unused prongs on a single phase bus bar only if there is no risk of damage to the neutral wires that may have to be...

You have already confirmed that something is wrong as both rcds have to be off to disconnect the circuit. You can track it down a bit more precisely by operating each mcb in turn. As you suspect that the ring is wired into two breakers then you need to have all mcbs off and turn on each one...

Do you know the original manufacturer/supplier of the roof trusses? You can contact them and they will tell you exactly how to make a good repair. You may be surprised at just how far the repair will extend onto the sound wood. Our house was built with a faulty roof truss. Despite being told...

yes that is a condensate trap. you can fit it at a 45 degree angle with the exit pipe at the lowest point. (I'm always amazed that builders think water flows uphill) Your pictures show two small bore pipes. What do these currently carry? Was the fan you removed showing signs that it had...

can you photograph the compromised pipe and post the picture here?

was there any condensate in the fan when you removed it? I can't see a condensate trap in the picture of the pipework you posted.

I've just had notification from my energy supplier that day electricity units now start at over 20p a unit., dropping to 14p a unit once I've met the minimum consumption. Night units cost 6p per kWh, I'm sure the costs were half that not so long ago. ------------ You could monitor your...

Are you planning on extending the area serviced by the existing supply or just to add extra sockets within the existing room?
