Peter I was truly amazed when I bought one of these: https://www.amazon.co.uk/C-K-T49145-1-Screwdriver-Terminal-Strip/dp/B002BDPFWM/ref=sr_1_15?ie=UTF8&qid=1513873121&sr=8-15&keywords=terminal+screwdriver how much more the breaker terminal screws turned with it without any more pressure, they are essential IMO, look at the end its a different shape to a normal cross head.

So extraordinary that it’s not even in the Wikipedia overview of all known screw drives. Seems to be a combination of a PosiDrive (improved Phillips Drive) and the traditional Slotted Drive:
Christian – bricoleur par passion, pas par necessité http://www.klussen-in-frankrijk.eu/
Wiki does mention these combination screwheads:-
Some screws have heads designed to accommodate more than one kind of driver, sometimes referred to as combo-head or combi-head. The most common of these is a combination of a <b>slotted and Phillips head</b>, often used in attaching knobs to furniture drawer fronts. Because of its prevalence, there are now drivers made specifically for this kind of screw head. Other combinations are a Phillips and Robertson, a Robertson and a slotted, a Torx and a slotted and a triple-drive screw that can take a slotted, Phillips or a Robertson.
Combined slotted/pozidriv heads are so ubiquitous in electrical switchgear to have earned the nickname “electrician’s screws” (the first screwdriver out of the toolbox is used, and the user does not have to waste valuable time searching for the correct driver). Their rise to popular use has been in spite of the fact that neither a flat screwdriver or Pozidriv screwdriver are fully successful in driving these screws to the required torque. Some screwdriver manufacturers offer matching screwdrivers and call them “contractor screwdrivers”, although the original concept of not needing to search for a particular driver being defeated as a contractor screwdriver is useless for non-combination heads. Slotted/Phillips (as opposed to slotted/pozidriv) heads occur in some North American-made switchgear.

Finally an end to the saga. Re-contacted the firm of plumbers who were going to do the major work (re-connexion to the water company etc) but which I rejected due to cost, in agreement with my co-owner friends. They sent a proper ‘devis’, arrived yesterday morning on the dot of 10.30 as promised and after 1 hour+ to empty the old ballon had the new one (100litres) in place and working, with hot water by 4.00pm. They are now contracted to do some jobs for the BandB owners replacing some old showers and much relieved to find we have at last found a reliable firm. Cost of my work was 947 euros which everyone seems to think is about right for the job.
Once again, a big thank-you to all of you who kindly offered information and advice – Peter.

Seems an awful lot of money to me for a 100 l ballon fitted.
Thankfully I’m still able to do do these jobs myself.

Why not replace with a ballon thermodynamique / heat pump for domestic hot water?
For your current and also the heat pump solution you could use a wifi time clock for better control than a regular mechanical version
You will use 1/3 of the electricity and dehumidify the basement at the same time. Then use a simple programmable timer to control time of use. Of course you will need a big enough basement to avoid cooling it out to much.
love working on our new old house.10th February 2018 at 20:07 #1822280

In view of the preoccupation with getting the right torque on terminal screws, I’m slightly surprised no-one seems to be bothering about periodically checking their tightness.
On large installations it is not uncommon to find some 20% or more terminal screws can be retightened by up to 1/4 turn after a couple of years, especially with multi-strand conductors.

Yes and for my sins I used âme souple conduit cable throughout pulled through plain gaine, I had a shedload left over from my business.
I really came unstuck when all of a sudden you could no longer buy prise murales with screw clamp connections, all the push connections were only suitable for solid core, I had to search far and wide and bought the last 200 from Castorama.
I will be doing a couple of revisions to the tableaux for the upcoming Consuel inspections so will finally get the proper tournevis and nip them all up.
If anyone wants a job lot of screw connection prise murales I have loads left over unused.
