    Bolton fire

    Government spends a few weeks every few years pretending to pander to the wishes on the electorate. The rest of the time they actually pander to the hoards of corporate lobbyists, often with personal sweetheart deals attached. There are 30,000 + lobbyists in Brussels. Great news for corporates, pan european and global interests and steering regulation and almost anything associated with government money in their interests. Shite for small companies, the self employed and ultimately any individual within a given country.
  2. This, or possibly less messier still decant using a small plastic container/jug on a stick type affair, hold the pipe into u bend and fill with the jug. once u bend is full place finger over one end whilst dipping the other into the tank and ready to go.
  3. You're welcome, you'll definitely thank me later too not having to put the blank in, an epic amount of faff, if the template shifts too much holding by hand just temp screw into the plaster as with the batten method.
  4. There's a few tricks, as drilling hole around existing hole is troublesome as you don't have use of the guide drill bit to stop it wobbling all over the place. Make a hole in something like 10mm mdf and use that as a template/guide/support to help start the new hole on its way, there's also a stacker mandrel available that you can mount two hole saws onto one mandrel - ok if you have the smaller hole size holes already which acts as a guide for the second (but won't work with very similar sizes as one won't fit inside the other). Can also use a batten screwed into the plaster, drill with the pilot through that to guide the hole saw but that leaves a few holes in the plaster that need to be filled. Dimmers also cause problems, not all of them are suitable for LED's, as well as the other way round as not all LED's are dimmable. Max flexibility if fitting first time round just go GBDamo's route with dimmable GU10, 240V and should then be just bulb changing when blown and no additional faff and max flexibility.

    I brought it up on the other thread. The London building code / act whatever it was decades ago specifically banned use of anything other than non-flammable materials on such buildings.
  6. The process is iteractive though, the equation I think is designed to extract the minimum cable size according to the values you have plugged in - either measured or calculated based on the cable sizes installed and the earth path resistance.
  7. Also as the cable size is decreased, the expected ia decreases with it (voltage is constant/nominal in the circuit). Tending to zero as the cable size decreases so will the fault current fall to zero. No fault current, no need to trip.

    There's a huge amount of regs, I'm wondering whether it is more of a case of wholly unsuitable materials being used and the compliance/regs being written around them to try and make them safe when they are inherently very unsafe. Also wonder about testing and compliance of such materials.

    It's a real problem - you have a building / occupancy that is sensitive to fire, some quite serious fire sources (kitchens) on every level, multiple instances in most cases. What do you do? Festoon the building with sensors, a hair trigger waiting to go off at any opportunity, which then gets ignored.
  10. Was just about to say the trip curve is non-linear so that once a high tripping current is detected - 3x, 5x ,10x for example then the trip is instantaneous regardless of actual current. No harm in having an excess sized earth cable, more durable too though 10mm gets somewhat cumbersome at times. So as Malthus says just use an overrated one and not worry about it, min 6mm. The Onsite Guide is often a much more useful document that the full regs, they are a nightmare to trawl back and forwards through with all the counter stipulations and interpretations. Simple lookup tables and rules of thumb saving a lot of headaches.
  11. Beat me to it. Aldi Barista americano (instant) very good too, cheap too. Add one of those electric whisks and warm milk - a cheap alternative to machines, some of which are not very reliable and require considerable faff cleaning them down to keep them going. Reckon good quality whisk and milk at the right temp would be a close match.

    Modular construction and design (probably), building based on sub units of room size and pre-manufactured elements to suit, big crane, hoist all elements into place )with the emphasis then on keeping weight down of all materials as they are prefabricated in larger sections). Makes it a factory build, just assembly on site rather than construction per se on the site. Delay might be having to wait for different cladding/ redesign or change the way the chosen cladding is used (remedial work to ensure sealed as much as possible against fire).
  13. IF the batteries were good enough and cheap enough it would actually be a solution to the storage problem, getting the car buyers to pay for it to boot. You could arbitrage the energy stored in the car battery to feed back into the system during high demand periods with premium payback rates or you could use the energy stored to supplement your own consumption during peak periods, Opened up an old box of batteries yesterday, some old NiCd and Nimh mainly, tiny capacities in comparison to newer lithium batteries, it is getting there but batteries will have to halve in price for EV's to be fully competitive with ICE, but that is only the point of purchase, the real savings are the running and maintenance costs.
  14. Fully filled they would have been a solid joint between the cement courses - almost like steel reinforcement and no voids/weak spots in the bricks for the bricks themselves to split, with a string mix no wonder it was difficult to knock down.
  15. Saw a programme on this - was about the construction of a whole street of houses in London (presumably standard London brick) , just carried on extending the brick kiln in a long run along the building plot with the houses being built in quick succession behind it.
