I deal with and use tech all the time. I am not against smart meters in general, but against the ****ing stupid designs and systems we're getting lumbered with, and the attitude of those pushing them. The smart way to deal with information security is to collect and store as little of it as...

Now, if you have a non-smart meter it's very unlikely you could be cut off or have the meter changed without knowing. People coming to the house is a big clue. And if they do, and it's an illegally obtained warrant because a supplier lied to the court and supplied false details (or they are just...

As you say, an extreme situation - and in practice won't happen. In part, that's why I suggested a large number of loads. Most large domestic loads are a) controlled and b) not in any way synchronised. So while the network load will not be constant, I expect it'll follow a fairly narrow spread...

Sounds similar. The 898HD had a special tool : Step 1, untwist wires, put through the 8 holes in the tool, wiggle a bit to remove the waviness and set them to the right soacing, trim to length. Step 2, slot the wires into the slots in the connector block, fold down the flap, use the parrallel...

FWIW for many years my preferred socket was the ITT Canon HD808 style. Crimped on in much the same way as an "RJ45" plug - and as Sunray says above, could be done qucker than it took to fasten the cable, unwind the pairs to the right places, and punch down 8 cores individually. Had the added...

Firstly, I'd second having a good think now about where you MIGHT want an outlet in the future. It's rather annoying to find you have them everywhere but where you currently need one. OK, don't go overboard as I used to recommend when fitting out offices - several times I've looked at a plan...

OK What is the power with 200V into a 50Ω load ? It's going to be 4A * 200V = 800W, or 4² * 50, or 16 * 50, = 800W. Only if you miss the fact that 2off 100Ω in parallel is 50Ω :unsure: But, we were discussing losses in the network. Let's assume we have a loop impedance of 0.1Ω, and 100off...

Consider something more sensible. Lets say 1000 loads, all running at say 10% duty cycle. So assuming independent loads, at any time there will be around 100 loads on - give or take a few. Double the voltage, doubke the current for each load while it is on. But at 4 times the power, the duty...

I think your just looking too close - take a step back. Let's assume all loads are controlled for a moment, and consider "lots" of end users (i.e. consuder a big chunk of network). And again consuder an impractical doubling of voltage. Yes, individual loads will draw double the current when on -...

OK, with non-controlled linear loads, as voltage goes up, so does power delivered, and DNO losses. Losses as percentage of energy supplied will be roughly unchanged. If you consider controlled loads - think ovens, immersion heaters, room heaters, ... ON AVERAGE, as voltage increases, current...

As you say, a significant proportion of loads will be controlled - and a prevalence of switch mode supplies, including high power inverter drives, where the load current decreases with increasing voltage. I suspect we're still a long way off the latter cancelling the former. But however you look...

Not necessarily. Don't forget that these days power flows can reversed in the local networks due to embedded generation (e.g. solar PV). So the voltage at the end of a line can be higher than at the transformer. The DNO likes to keep the voltage up as it minimises I2R losses. Then embedded...

Yes Indeed - and that's what I have installed, but currently only have a gas boiler (and immersion heater for backup). The other benefit is the the store acts as a neutral point that decouples not just the heat sources from each other, but also the geat loads bith from each other and the heat...

Doesn't necessarily work that way. Let's say we want the top of the tank at 60°C, and the boiler is set up for a max delta-T of 20°C (stanard max for gas boilers). Absent "something additional", to get 60° out of the boiler means putting 40° in - so you have to partially heat the entire tank...

But a route for actually getting it from A to B might not be - at least, without ripping into the decor.

Had something similar not far from me. The town was getting fiber via one of the non-BT outfits. For whatever reason, they couldn't use existing infrastructure so wanted to put a pole up. The residents on the "nice street of detatched houses" objected - so missed out on fiber.

I was assuming all the gaps between slates would provide ventilation. There's a void between the roof and the flat ceiling below - which I'm assuming won't be insulated. I'll probably try sticking a camera in when I get the old fascia off and have a look.

Has a "safety moment" thing at work a while ago. A gouger was working, tugged the cable a bit, the connector came off (just like above), and the bare end dropped onto a gas cutting torch and the arc cut the torch into two pieces.

The thing is, it's no longer a non-domestic thing given the prevalence of solar systems with battery storage, and EVs with V2G facility. And some of these include the ability to operate off-grid like a UPS. A schoolmate went on to be an ekectrician and got very badly burned on an industrial...

Here's my take on it. I'm assuming the small box to the left of the meter is either a timer or teleswitch to control the off-peak supply. I think it's connected into the round terminal box - supply from a circuit in CU3, via the FCU, via the time/tele-switch, and finally controlling the...
