Who’s really being silenced on Twitter? | 220v Contactor Relay

For the voltage setting, I thought that wattage equaled volts times amps? Shouldn’t the waste heat be the same regardless of whether it’s drawing ten amps at 120 or five amps at 240? Or is it more complex and nonlinear than that? I’m curious.

On our case a combo was the right solution. We use a contactor (a relay) to switch incoming power because it’s either on or off. But we use a SSR to switch elements on and off because they cycle on/off many times a minute.

(No portable generator can power an entire house; for that you’ll need a different category of generator, called a home standby or whole-house generator, which will cost $2,500 to $4,500, plus installation, something that can run in the thousands, depending on where you live.)

Driving the Niro PHEV is a better experience than the standard Niro — when I drove that hybrid, there were a few stumbles with the dual-clutch transmission when cold. It seems the larger, more powerful battery and motor combo smooth out the rough edges of this transmission. The greater electric torque makes getting off the line brisk, almost fun.

We were pretty close to that 40% rule when our controllers started to fail, which is probably why they only started failing after our customers had use the controllers a few times. We were pushing 22 Amps through 40 Amp rated parts. In other words, using a component at half its rating still won’t cover for substandard parts! Our solution was to find a part that was manufactured to spec and also use the component at half its rating and we’ve not had a verified SSR related failure since.

From the top of the Sony Alpha A33 camera body, you can just see the stereo microphones, located on either side of the flash hot shoe on the sides of the viewfinder / popup flash housing, as well as the three hole grille the speaker (above the Finder/LCD button). At the top of the handgrip is the popular combination of a shutter button surrounded by a power switch, making it easy to quickly power on the camera and snap a picture with one finger. The Finder / LCD button allows the A33 to be manually switched between shooting with the electronic viewfinder or the rear LCD panel. Upper right of this is a D-Range button that provides access to Dynamic Range Optimizer and High Dynamic Range shooting options.

Nissan has said that most people who get their LEAF charging stations installed by AeroVironment will pay around $2,200 to $2,500 in hardware, permits and labor—$750 of which is for the actual charge station hardware. While the pictures are interesting in-and-of-themselves for those of us that care about what happens under the hood of all of our equipment, the bigger question the pictures bring up is what, exactly, you’re paying for when you plunk down your $750 for the hardware.

“Engineering types”? – I would suspect business or accounting “types” to be responsible for “saving” on maintenance. Engineers normally know, that maintenance is important.

But 110/120v A/C? that stuff is baby-play, as long as you realize that you shouldn’t use both hands, or use grounding straps, it just kinda buzzes, I’ve played around with TENS devices that had more (felt) kick than it…

He’s not using a pool side remote box but emulating it. But what if he wanted to use both? At the moment it’s simulating the buttons. What if you need to both simulate the buttons and also read them if they are pressed?

“The Psychopath Test” by Jon Ronson is a great book about it, the guy who invented the checklist now used to diagnose psychopaths, has his pet theory that psychopaths with power are the cause of many of the world’s ills and inequities. His name’s Bob Hare, and he probably knows more about it than most other experts.

I’m not going to argue with your statement, it just seems funny to me that someone would tens of thousands on an Electric Car but still be using a Gas lawnmower!:)
