#PreferLinux mentioned switching off at the mains socket. Do that, but still test; that saved me once when the switch was faulty. Yes, that socket was replaced, pronto!
The first time I hooked up to HT it was a 32+ inch screen (about 27KV) and it launched me into the air and I landed 4 meters behind where I was sitting. The second time was a 27 inch (about 24KV) and there was a wall about two meters behind me and I was slammed into that so hard that I was bruised in many places.
The purpose of this project is to fabricate a heater for use in a 3D printer. Nobody is suggesting that we should somehow 3D print a heater.
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.
I’ve never used a 3D printer but I imagine the printer nozzle is conductive – a small misalignment, the nozzle breaks through the solder-mask, your whole printer then becomes live, blowing up the PC connected to it at the same time.
I heard from an instructor that some guys from the national power company use full PPE when switching on/off old main fuses in domestic installations (230V, 15 to maybe 60A). These things are fully plastic and can be operated by everyone, so no PPE needed, but it seems like they explode sometimes – maybe because of the dust you mentionned.
I suppose a more flexible grid, with more cheap gas plants, which can fire up quickly, made this possible, as well as making the grid itself smarter. There was a rush to build gas power plants a while ago, since of course gas isn’t going to run out any time soon or anything.
All silly, make graphene in a blender combine it with acrylic paint, then paint it on. Making heated beds is anything but an art form. Or just use graphite.
The QD terminals are totally fine as long as you have a ratchet crimper, which I saw you said that you did.
This! I just want to add: >3. Verify that the system is really dead. Use an appropriate tool. Test the tool, test if the system is dead, retest the tool. It should be broken or may have broke while testing. >Use nonflammable clothes. Yes! Synthetic materials melts, sticks to your skin and burns – you don’t want this! >Use electrically protective gloves. and check them before use! Do not work alone and if the second person has no clues about electricity instruct him: -What NOT to touch. -CUT THE CURRENT before trying to help somebody that has been electrocuted. -Where the main breaker is and how to operate it. Have a fire extinguisher and a fire blanket (if you catch fire) handy.
Alternatively, the stillborn 42V automotive power standard is another solution. http://en.wikipedia.org/wiki/42-volt_electrical_system
No, thatâs not a typo in the fact box up top. I drove the Niro PHEV a total of 253.2 miles, and topped off the tank with 3.107 gallons of regular unleaded. 81.4934 miles to the gallon very nearly doubles the mileage I observed last year in the standard Niro. 26 miles of all-electric range makes a serious difference â there were many days where the gasoline engine never fired.
