You think you've found all the nails-through-wires, but there's one more. I once had a friend who's garage light switches suddenly started operating different lights, and I traced it to a 16p nail that a roofer had put through two separate runs of wire, one of which was a three-way switch send, and the other a regular single send. The nail shorted one leg ...

Turn off all the breakers, try them one at a time and see when the voltage returns, this should help to locate the problem area. Once you have the area found, turn on all the breakers, except the breaker to that area, and check it again. Now with the problem breaker/breakers off, go through the devices and check if any have a bad wire. I would start with ...

1) Yes, your interpretation of the layout and markings seems to be correct. 2) No, it's not a problem, it's a very typical setup. You can have breakers totalling more than the total capacity of the unit, on the ground that you are unlikely to be running each circuit at or near capacity at the same time. A MCB (or RCD, fuse, etc) is designed (and sized) to ...

As my high school chemistry instructor made us learn: Do as you oughta - add acid to water. If you add water to acid, the reaction dynamics work out badly and you get the MSDS warning - the water boils, this spits acid solution all over, and is dangerous. If you add acid to water, the reaction dynamics work in a more favorable fashion, and nothing ...

This leaflet just contains some general information concerning the product. The only thing relevant to installation is in point 5 (labeled 五). Basically, the user is told to connect what are literally labeled as the "fire wire" and "null wire" (火线 and 零线) -which I interpret as respectively the red and the black wires- to an AC supply of 180 to 250V, 50 to ...

Seems very unlikely. Consider that lots of harmful industrial chemicals are used in the production of electronics to begin with. Usually most people's concerns with VOC's associated with painting have to do with human health, especially the young and old. It's generally best to minimize any contact with these by ensuring lots of ventation and if possible, ...
