Failed driver/PSU. When switch mode circuits fail, you either seem to get a failure mode where it goes to start up, but cannot maintain the output so falls over and starts again resulting in pulsing, or doesn't even get anywhere near full output and just outputs a very small voltage that can...

If that is the case, then it doesn't meet the relevant standards as BS 1363 requires it to accept 3x2.5mm, or 2x4mm² per terminal

I'll make sure *not* to follow his advice when doing something like changing a socket in a hospital waiting room, or connecting a tea boiler in the canteen of a factory thats got a load of CNC milling machines going on the machine shop floor.....

Bloody hell, you've got good eyes! - Yes there seems to be

There is a random new colours twin and earth of a small ish size picking up live and unswitched live. It could well be indicative of something not quite right, I'd be tempted to make the ends safe in connector blocks and then see what doesn't work when you have changed the isolator. I have a...

The alternative is door retaining magnets, controlled by a relay from the fire panel, but while there is a chance of it being cheaper in materials, it'll need a lot more labour to install (You haven't got to keep batteries maintained at each location though)

I'm wondering if I probably ought to have a type 1 at the orgin. I have got a type 2 at the main DB in the garage (fed by switchfuse at orgin) which I added when I put the zappi in. The only overhead bit in the supply to my house is the ABC above my front garden, but the lines continue along the...

Quite a lot of the time when people(installers, wholesalers, even manufacturers sometimes) talk about type 1 SPDs what they are refering to is a device with the functionality of both Type 1 and Type 2 devices (and sometimes type 3 as well)...

It was either free or negative from half ten to half three today and I was in. So I washed and dried two loads of washing, ran the dishwasher, boil washed the dog's smelly blanket, topped the car upto 90% after going out for lunch, did some 3D printing I'd wanted to get done, while busying...

Interestingly they are not actually compressed air at all, if you wanted to transport compressed air you'd need a far heavier guage container. Instead to get a good volume in a thin walled container they need something which compresses down and becomes a liquid at relativly low pressures, which...

Well, Yes and No, It does seem that the whole smart meter thing is perhaps just starting to turn a corner and be useful and actually help with energy efficency. If you take the average consumer on a flat rate 24p/kwh, it doesn't matter to them when they do their washing, run the dishwasher, etc...

I think you still get it, I'm on agile and apparently I still get it it (though the benifiets to me will be small, as any time this applies, the power is likely to be sub 5p a unit anyway). I think with go (the inteligent or non-intelligent version?) you get x number of hours at night that are...

Remembered about this, and went and took some photos to give some context

I'd personally say the electric one might be worse, unless its got a mis-fire the petrol one should only have sparks inside the cylinder, the electric one will be generating them on the commutator as you say, and the surface temperature of a an engine is not generally hot enough to cause issues...

I only have a dropped kerb from where the entrance is on the minor road (Housing estate road/cut through, not B-road) not on the A-road, and I cant think I'd be allowed one as I dont have the justification to need one, so I dont think they would permit one close to the junction on a major road...

If as plugwash asks the EVSE has a grid limit function set to whatever the size of the supply fuse is, then that becomes irrelevant as that cant contribute to pushing it over the limit because it'll scale back as far as required to avoid that, so the only real worry left is the showers, if you...

Just posting here to see if anyone can help me get a start on this, basically my driveway has been a mess since we moved in over ten years ago, missus is on at me at get it sorted*, going to get someone in to do it, but I need to try and work out what I'm asking them to quote for first.... and I...

Thats true if the Thats more or less true if they are just in-line on the same circuit, with nothing protected only by the type AC that is not also protected by the type A (We will forget that re-used cooker circuit might have concealed cables in the wall before its terminated into anything...

You are looking at it the wrong way around, the upstream type AC does of course not compromise the ability of the downstream type A to function, however the presence of the downstream type A does not shelter the upstream AC from being affected by the load. The type A is guarenteed not to be...

Personally in that case, I'd look to re-instate the cooker cirucit to pretty much the standard arrangement for if you need it future, so that is 6mm from board, through isolator and then onto a box for an outlet below the countertop. Fit a dual accessory box under the counter and then a couple...
