    Has anyone got an apprentice

    I've had a mixed bag over the years, the more recent being the worst. I think it is a combination of poor education, by this I mean that discipline lacks and social attitudes. Many teenagers believe they are more entitled than they really are and when they hit the work life its a shock to the...

    Why are there so many secrets during job planning

    In my experience the wife usually wants as much as possible everywhere and the husband wants as little as possible to keep the cost down. Sometimes I may offer a suggestion in anticipation that hey may change their minds at some point anyway when it's too late and more aggro for me. You often...

    How does fault current loop? "Earth Fault Loop"

    Just to add, the safety circuit (earthing in this case) when required, is along with any safety device the most important part of an installation. Selecting the correct equipment for safety in an installation is essential, and this includes cable, connectors, devices...etc . It is also...

    Working for the self.

    Agreed, I fell into this trap many years ago and still paying the price even today! I still get phone calls from family members I don't even have normal contact with for years who expect me to drop what I'm doing and go help them out (usually to save them a few quid). These days I remind them...

    RCD's not tripping at all

    Yes good point, I've had this situation in the past, never give it a thought in response to the OP!

    Do plugs have to be fire rated?

    Yes, its all about time and exposure. A plastic Rawl plug will fail once the metal screw has heated up enough to soften the plastic plug to an extent where it easily pulls out but in most situations the building is likely to have been vacated by all by the time this happens. Even so, it might...

    RCD's not tripping at all

    As Tim said, It could be possible but not common for both RCD's to fail, unless they have been damaged somehow or stood for a long period of time, as James mentioned. Even so, I'd be suspicious of sticking RCD's and would recommend a swap out even if they prove to be unstuck and test ok...

    Landlord's EICR query

    An EICR is to determine if an installation is safe for continued use. You have stated this yourself (in bold). Whether the installation of the CCU had been notified is irrelevant. All you can do is comment on the current installation's condition, and if required apply codes and/or make...

    Is 187 hours of work reasonable?

    Who changed and to what extent the plan and what was the sequence of events? Based on what you have stated (though there still isn't enough detail to make a proper judgement) It does seem very excessive. There seems to have been a lack of communication from both parties involved. Have you...

    Is 187 hours of work reasonable?

    Did you not agree a price prior for the complete job? Usually you would expect a price with caveats that additions to anything initially agreed would be discussed, agreed on, and charged extra accordingly. On face value it does seem excessive but, in the electricians defence without full...

    Puzzling tripping problem.

    As James said you need to do an insulation resistance test.

    Plumbing Question - Shower not hot

    If the water is hot at all other outlets then this directly points to the shower mixer valve as first point of call. However, I have come across once a bath that had the same issue, but this was down to the water flow rate, where if you turned down the hot tap to slow the flow rate the boiler...

    UK New consumer unit required for updated kitchen

    How many times have we all been there! I fitted a consumer unit a few years back, just over a month later the client called to complain that her fridge freezer had stopped working. I was perplexed as to why she thought it was anything I had done. She said "I've had that fridge freezer for...

    The fastest RCBO in the world

    For most intent purposes what we perceive as instantaneous can be described as such, especially such that our senses and reactions are way way slower than the speed in which electricity and light propagates. But there is no such thing as a cause and effect mechanism which is instantaneous in...

    Maths needed as a spark?

    Often my trainees have complained about having to do certain things during training that they probably will never use again. However, I always point out that, especially so when inspection and testing and/or designing a slightly different than common install that having an understanding of how...

    The fastest RCBO in the world

    I'm a member of a few science forums, its a passion of mine. So my apologies, I just find it so fascinating and just wanted to share with bore you all. :D

    The fastest RCBO in the world

    There is no such thing as instantaneous cause and effect in the way you are imagining it. Even if the device operated at the speed of light, (around 300,000 Km per second = 186,282 miles per second) it would still take an extremely small amount of time to operate . Albeit, this would be so fast...
