Microsoft announces Xbox One keyboard and mouse support with Razer partnership | 25 Amp Circuit Breaker

The 40 Gallon Hot water tank takes 22 Amps with both element on. And you used a 25 Amp relay. What really happened is you under rated your relay. Solid state or Mechanical does not matter. At the Max for a load it should never use more then 80% of your ratted load of your switch/relay/controller.

Heater might be pulling 22 A when hot, but on power up … likely much more. Think about incandescent lightbulb or electric motor, for example.

A user calling himself "Tango" over at the MyNissanLEAF forum posted them yesterday saying, "I wasn’t sure if anyone posted pics of the insides yet, so while they were [installing it], I took a couple of pictures of the innards."

Speaking of mains power and gas pipes, I live in a 100-year-old house which has some rather dubious wiring (though, perhaps not as bad as the knob-and-tube it started with). The kitchen’s gas range had been in place since puke green was the preferred color, and its power cord (for the clock & timer) was, unbeknownst to me, seriously frayed. The range’s gas inlet was connected to the shutoff valve on the wall with one of those scary-looking flexible tubes (not a modern, yellow insulated one, but rather bare metal). Well, one day the range got pushed back for cleaning, and the exposed hot lead in its power cord brushed that gas line. ZAP!, followed by a roaring jet of flame from the large hole now in the flimsy gas line. I couldn’t get close enough to the shutoff valve to use it, so I had the frantically seek out a big wrench and shut off the gas where it enters the house in the basement. By then the wall behind the range was well and truly aflame (way too big for my wimpy little fire extinguisher to deal with), so I threw pans of water on the fire. I figured the breaker for the outlet the range was plugged into had already tripped, but it later turned out that the contact had been too brief for that and I was throwing water on a live electrical circuit–no harm came of that, fortunately.

But at the very same time, if the rectifier dissipates enough energy for this to be a concern, then it is probably a poorly designed power supply to start with. As most power supplies will be designed for the voltage range of 110 to 250 volts AC. And as it will draw the most current down at 110 volts, then this is where the manufacturer has their specifications chiseled in stone, as if we want 1100 watts, then we need at least 10 amps when we have 110 volts AC on the input. This means that we “effectively” have 5 amps to dissipate per diode.

I didn’t buy one, largely due to some compromises in the plug-in version. The very high load floor in the cargo area was a big downside for me, as it really limits cargo space.

Naturally, the instructions are a bit specific to the Pentair system he has. However, it isn’t as specialized as you might think. The project relies on the connection for a wired “spa-side remote” that most modern pool systems support. The electrical connections for these aren’t quite standard, but they are all very similar, so you have a good chance of reproducing this for your setup assuming you have a connection for one of these wired remotes.

In the old days, waaay back in the 20th Century, you’d buy something from a vendor that had a good reputation. It was in their interest to keep their reputation, because that’s where customers came from, so they’d make sure to only buy their materials and parts from reputable suppliers. And they’d do the same, forming a chain of reliability and trust built up through experience and everyone’s mutual need to keep up a reputation.

Sweep Panorama mode makes shooting panoramas easy, but not entirely brainless: It often takes me a few tries to get just the shot I want. The camera throws away a fair bit of the image area top/bottom and left/right, to insure that it has enough room to get everything aligned properly, despite your having angled the camera or not having swept perfectly horizontally or vertically. Sometimes, you can end up with your main subject higher or lower in the frame than you’d anticipated. It’s also easy to get a tilted horizon, if the camera orientation or your sweep direction is a little off. I found the A33 and A55′s level indicator and viewfinder gridline displays very helpful for avoiding these problems, although there was a little learning curve for me to make effective use of them.

The plug-in Kia Niro has an 8.9 kWh battery (vs. 1.6 kWh in the regular car). You can quickly estimate the amount of kWh you used in the week as long as the battery was fully drained every time you plugged the car in (it’s fully drained if the gasoline engine kicks in) and you know how many times you charged the car.
