    Potential Overloaded? (Kitchen Oven & Hob)

    Popped round my old dear's yesterday. She quite fancies replacing her ceramic hob with an induction one, so I thought I'd take the oven and existing hob out to see what state the wiring is in (property built 1930s although I expect probably had a refurb at some point in the 70s or 80s, but...

    Do others filter the potential time wasters?

    I am sure there are far more time wasters contacting me than a few years ago, or is it just me being grumpier in older age. I think I'm usually good at sussing out the time wasters and I would say that around a third of the people who contact me I don't even arrange to quote them as I believe...

    Potential overload of ring mains

    At a house viewing I saw a dozen electric radiators connected mainly by plugs into wall sockets, one or two (in bathrooms) connected to fused spurs. I calculated nearly 14Kw and I'm given to understand all these rads are connected to either of two ring mains with 32A breakers. A quick look at...

    Potential circuit faults - RCD/ Megger

    Hi folks, In your opinion, do you think there would ever be a situation where an RCD (presuming it worked) would not pick up a problem that a megger test would? i.e an RCD would trip if there was ever a L-E, N-E or L-N fault

    Main bonding made to separate earth rod?

    Evening all.. I have just been to a clients house to quote for some work and when checking the Main bonding I noticed that it just had a 10mm attached to the gas pipe and then straight into a separate earth rod, it was the same for the water (had it's own earth rod).
