That RD415 looks like a nice cable, but is it only available in 1.5mm² ? Those Aico bases are hard enough to wire with 1.0, I wouldn't like to do them with 1.5 :eek:

Actually, yes they have "learned" to play. The mumber of possible moves even when looking only a few moves ahead quickly becomes too large to handle - which is why early chess programs got got thrashed by even moderate skill players. At the start of a game, there's 20 possible moves, then 20...

Yes, a decent option. But ... What are they called ? Any examples of where they are sold ? Do they do them in the different sizes/shapes needed - some conduits are round, some are oval. I imagine "bush" will appear in the description - but that's a rather generic term to search for.

But considering the primary function for most RCDs - pritection against direct contact. You'll conduct "considerably more" than 30mA - and trigger all the RCDs. The only one's that won't trip will be thise that are slow enough not to have triggered before another has physically opened its...

Except if you refer back to the first post it specifies White in Ireland

Parallel conductors are allowed for in the regs : 433.4 Overload protection of conductors in parallel Where a single protective device protects two or more conductors in parallel there shall be no branch circuits or devices for isolation or switching in the parallel conductors. This regulation...

Can you clarify: is this existing cable connected to anything or not ? If it's still connected at the house end, what's on the other end ? There is (in practice) no discrimination between a 10mA and 30mA RCD (and 100mA RCD for that matter) - in the event of anything but a fairly high resistance...

Indeed, and it's "really annoying" when many of the "AI" solutions I see making the news are really noting more than basic machine learning - simply reading lots of input-output sets of values and inferring what the relationship between them is.

No, black is a standard colour (along with brown and grey) for line conductors and therefore does not need sleeving brown.

Err, so you've forgotten the number of threads here (and in other forums) where the EICR claims lots of stuff must be done, but in fact it's a made up excuse for fleecing the customer - or at least, somewhere between that and reality. Not saying that's the case here, but there is certainly scope...

And so we get ‘Dangerous’ daffodils and 10 more ‘elf and safety myths, Common health and safety myths in schools, Common work at height myths On that last one, a while ago I was doing some work for a client and needed to put up a couple of WiFi access points (not very high up on a wall) - so...

Not 3 supplies, 3 (or more) circuits. Could be one conduit for the sockets, one for downstairs lights, one for upstairs lights. Our house is like that, particularly from the CU up to under the first floor, where one carries on to the socket above (one end of the upstairs RFC), and one carries...

An update. Went back and had another look. If we get the store cool then it seems to work OK - modulates pump and burner to maintain 15˚C T across the coil. There's a disappointingly high T between coil and store - so it soon starts running out of headroom and throttles back. But it's working as...

Or the direct BBC link https://www.bbc.co.uk/news/articles/cp8zpj7zz5do While that is sad, it shows how "the Amercan way" is getting pervasive over here - it was only a matter of time. So bloke waves a long pole around near power lines and gets zapped - and call isn't for better understanding...

You mean, like no-one would make a prank call for whatever reason. Not heard of it being done to cause power cuts, but then we don't have DNOs turning off the power willy-nilly (yet.)
