Facebook and Google hit with $8.8 billion in GDPR lawsuits | 25 Amp Circuit Breaker

By not distributing the three wires and only distributing two you try to limit the possible potential between neutral at the sub and neutral at the house by using multiple earths anywhere you can so in this case when lightning strikes the local ground potential rise applies to the ground and to the local end of the neutral/earth wire. Massive currents may flow through that neutral/ground and eventually through the low value resistor at the substation but under no circumstance other than network failure is it possible to get a neutral ground potential of significance with a premise. The low value resistor at the sub limits the current to one that the network can handle.

So it’s the usual forgettable Toyota – but still hugely preferable to the godawful Prius which is a truly horrendous looking vehicle 

But even so, you’re not likely to be arrested for adding your own electrics, I dunno that it’s actually illegal. Charging money for it would be different. But I can imagine insurance companies would hold it against you. Any excuse, of course. You’ll have to check the teeny-weeny print in your policy, and the extra documents they didn’t send you. But it’s not impossible for someone to fuck up mains wiring and burn their house down, and that would be their fault.

It’s what this high technology allows that’s so exciting: real-time, phase-detect autofocus while firing off up to seven 14-megapixel frames per second in the A33, and ten 16-megapixel images per second in the A55. Few other large-sensor cameras offer frame rates this fast. DSLRs rivalling the A33′s speed are available for a little over $1,500, while only professional cameras that cost around $5,000 can match the speed of the A55 — and they’re still not capable of real-time autofocus between shots like the new Sony Alpha SLT cameras. Real-time phase-detect autofocus is also constantly available in Movie mode, something no current SLR can achieve.

Note: Not all certifying agents offer online lookup, and some have a lag time for posting new certificates. If you are unable to find a certificate online, contact the certification agency or supplier for further verification.

For the person who jumps up and says “coatings insulate the water from the trace”, well no it doesn’t, we are talking about AC voltages and water that has formed over a large trace (even insulated) forms a capacitor that will conduct AC even when you have a DC insulation. Even if it did you then still have the exposed solder pads.

It’s *mostly* read-only. They usually have a LED for power-on indication. You could stick something to the front to detect that, if you needed a response. Tho for things like lights, usually the user will press the button again if they don’t come on the first time.

How about trying to say something accurate for a change? Almost everything you say lately is provably WRONG.

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. All of the earth ground leads are also screwed into a bus-bar linking them all to Neutral.

SSRs can actually contain what is used here: optocoupler+triac or they may use optocoupler+mosfet. Just like individual triacs you will find that they suffer from the same issue: high power dissipation. A quick looks shows BT137 will burn 20W to switch a 5A load, I see 6W for the first 10A SSR I encounter. This is too much to dissipate in a small junction box isolated inside a wall. Meanwhile, a 10A relay will dissipate maximum 2.5W through the 0.1ohm contacts.

Capacitive or Resistive Voltage Dividers are not really an option for this device since the ESP8266 draws a relatively high current. You would have a high power dissipation (resistive) or a VERY large capacitor. A more complex design or a small transformer has to be used here.
