The only place neutral is bonded to Earth ground is at your electrical panel, open it up and look at it. The white wires will all be screwed into a giant bus bar, which makes electrical contact with the electrical panel enclosure.

Wonder how long it’ll be before Toyota marketing changes Aygo to Starlet, the Yaris to Tercel, GT-86 a Celica and CR-H a Space Cruiser?

people remember “the good old days” and they forget all about the horrible accidents and fires and massive death that came from ignoring fire regulations

The time-multiplexed full-color RGB pixel technology generally worked well to deliver very high resolution with no gaps at all between the pixels.

Farewell, then, Toyota Auris, welcome back Toyota Corolla. Goodbye countless marketing millions spent establishing a new name and fresh reputation, hello old friend. Out with the old and in with the older, although it is surely not just me pondering why the passing 13 years have replaced recollections of the dull but worthy family hatch with a nostalgic fondness, lightly sizzled by memories of victorious Castrol-sponsored world rally cars?

No need, really. You just need a few mates with smartphones – just enable the wifi hotspot on each of them, place them roughly in a circle and put your coffee in the center. Make sure to dismantle the circle before you reach in for your cup though if you don’t want to get fried too – safety first!

Far as I’m aware, you’re supposed to get a qualified person to fit an electric cooker. Of course, doesn’t stop me doing it. Actually more complicated than you think, it’s not just 3 terminals, there’s a dozen bits of plastic and metal in there that all need putting back in the right order.
