    Instructions, should they be required, what should they say, etc.

    I read the manual for an Erbauer battery drill, (Screwfix/B&Q own make) trade rated drill. It said not to leave the battery on charge unattended, so when you return at the end of a days work, you go into the depot and watch the batteries recharging? I use Lidi's own, Parkside, the battery even...

    What to do, once we get rain, to get lawn back.

    A bin left out in the rain, has just a covering of water in the bottom, so yes seems a lot, but really we got very little, hopefully enough to stop wildfires? Never worried about it in the old house, it never got too hot in the house, and the pond never seemed to dry out, this house is so...

    Instructions, should they be required, what should they say, etc.

    Many videos on YouTube etc, have the speech written below, and often I see the wrong word, etc, lbs instead of £ etc. In 6 days time, the plug in solar becomes legal, and it has to come as a kit, with instructions which are a legal requirement. And what they say will be very important. A small...

    Interesting Regulation of Yesteryear

    I remember the signs "Danger 440 volt" everywhere as an apprentice, but across two phases of a three-phase for a single phase of 230 volts is 400 volts, 240 volts are 415 volts and only at 250 volts would it be 440 volts. So in my lifetime (I am 75) it has never been a nominal voltage of 440...

    What to do, once we get rain, to get lawn back.

    Well it has rained, mainly at night, but the grass one side of the drive has already started to grow with a vengeance. But under apple trees, there seems to be no change. Around 5 days in all, but since at night, not sure exactly when it started. The flowers have really come on.

    If a hydrogen car is 50 MPH faster to a diesel car, why are we looking at electric?

    JCB seems to have proved their point.

    The mole!

    That's the point, they are laid on the old concrete slab, there was some concrete stuck to the bottom of the slabs, so to stop them wobbling I put a small amount of sand between the slabs and the brick sets, the brick sets did not quite touch the house, so cut one in half long wise, to fill that...

    Instructions, should they be required, what should they say, etc.

    OK, now making more sense, seems two models, one is an electric oven and gas hob, the other electric oven and domino hob half gas and half electric. So we know an electric over will likely take 2–4 kW so if it had a domino hob then it will use the full 5.6 kW, but with an all gas hob, will work...

    Instructions, should they be required, what should they say, etc.

    I remember a multi-fuel boiler, it was German reparations after first world war, would work on coke ovens gas, blast furnace gas, oil or coal, although it was hardly ever used with coal. And it powered a 12 MW generator which at the time we thought was big, I have since worked on 750 MW so...

    Thoughts on tidying up a garden wiring box

    To export TN-C-S out of the bonded area can cause a problem with a loss of PEN. And it is near impossible to know if the supply is TN-S as at the head they and look the same, so we assume it is TN-C-S even if really TN-S. So in the main outdoor equipment is class II, so earth not used anyway...

    Thoughts on tidying up a garden wiring box

    Any box where the wires are fixed makes testing easier, sometimes called a wiring centre but there is no real need. That is rather a complex question. What we are really looking at should a garden be TN or TT earthed. This may help but it is down to what is in the garden, and not something I...

    The mole!

    With the help of our cat, it came into the house through the cat flap. We could hear something around the fridge did not know what at the time, so put down humane mousetrap. Mole it seems strong enough to lift the lid and get out again. However, cornered by the cat, so grabbed it, lovely little...

    Do I need an electrician to replace a hob?

    The fan and rear element runs and the grill turns on so it is cooking from both sides, so only need to turn food once, works well with bacon. I think the selector on our oven has 12 options, there are elements at side, top and rear so it is a bit like the old Rayburn oven where you could...

    Water based paint, and thinning it down.

    We used to use oil based paint on wood, but the drying time was a real problem, it would seem dry after two weeks, but try moving the benches etc, and we still got paint on our hands, clearly where some bit was a bit thicker than it should have been, so there was always a worry putting benches...

    RCD tripping issue (again) - Earth Leakage?

    I think we all know, not really referring to a dead short, but a low resistance connection, between earth and neutral, your comment is likely to confuse a non electrician.

    Electric Saw

    Yes I have the Scorpion one, was my dads, and I used it a lot, until I got the Lidi multi-garden tool, looks like this but one shown is tool station. 40 volt (two batteries) with strimmer/brush cutter, hedge cutter, and lopper (little chain saw) on a stick, and in spite of the problem...

    Anti-growth paving sand

    I know should use sharp sand, not builders sand, but my daughter used the sharp sand for brick laying, so I only had builders sand to hand when laying the slabs, but not convinced it makes that much difference. I have no intention to do a re-lay with sharp sand.

    RCD tripping issue (again) - Earth Leakage?

    All my garden sockets, are either plugged in, so easy and quick to disconnect if a fault is suspected, or on their own dedicated RCBO.

    Do I need an electrician to replace a hob?

    The new pacemakers it seems are now compliant, and can be used with the induction hob. The induction hob puts a larger % of energy into the food, and the food needs the same amount of energy as it has always needed, so an induction hobs average power use must be less than a resistive hob. And...

    RCD tripping issue (again) - Earth Leakage?

    If you have a neutral to earth fault, the turning items on/off often does not work. As the load increases the resistance in the neutral wire means the voltage differential between neutral and earth also increases, which in turn means the current in any path between neutral and earth also...
