AMP Seeks More PJM Scrutiny of TO Projects | 220v Contactor Relay

I liked your article. It had a lot of good pointers for others. It may be a good idea to add a red indicator between neutral and ground for the two incoming 120v lines. That way, if the hot and neutral are reversed, the light will come on.

If ever there was a right time to change the name, it’s now, as this ground-up, all-new car launches with all the incumbent R&D investment and expectation you might expect for a vehicle that has been benchmarked to beat the class best. So while you might reasonably argue that it would have been more straightforward if the naming U-turn hadn’t been made several months after the car was unveiled as an Auris at this year’s Geneva motor show, the truth is that when Corollas start running down the line in Burnaston, Derbyshire in a few months time, surely only Google will recall it.

No, it’s far more likely a combination of the strength of your flexor muscles (biceps) being stronger than your extensors (triceps), a bit of spinal reflex (sudden stretch of pain signal = withdraw limb) and observer bias; you’ve probably seen people electrocuted with 120v AC more often than 120v DC.

The US had the luxury of a relatively new infrastructure to deal with, just like our cars we built roads to fit the cars Europeans built cars to fit the roads, high RPM small displacement, VS low RPM large displacement in US. Power in Europe had to be retrofitted into 300 year old buildings, much easier with higher voltage-thinner wires, if you have ever been over there they also run their plumbing on the outside in old buildings because there is nowhere to put it inside the walls.

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

We drive about 30k miles/year, lots of long trips. After a trip, we usually pull in with 25-50 miles of range remaining. No problem – charging to the normal 80% is < 7 hours.

FR4 is actually quite a good insulator. It’s only real failure is when you have impurities on the surface of the PCB in very high humidity conditions. The impurities will cause the surface tension of the water molecules in air to lower and as this happens the water will condense onto the PCB. The water on the PCB reduces the effective creepage clearance and can cause a flash over or arc.

But there is other sources for the “warmth”, all though, if one lives on permafrost, then many of those sources are off limits. Since it is typically either boring a hole into the ground (Not always an option due to geological reasons), putting a hose that is coiled under the surface of the ground, typically a meter or so down. (the ground temperature a meter under ground is typically rather close to the average year round temperature (though dependent on what soil one lives on). We would find permafrost if the average temperature is below freezing.) Or sinking a coiled hose to the bottom of a lake or river. Since the temperature at the bottom of lakes is typically around 4 degrees C. (This though requires that one has a lake on one’s property that doesn’t completely freeze to the bottom… (So a depths of at least a few meters is typically required for cold climate.))

The time-multiplexed full-color RGB pixel technology generally worked well to deliver very high resolution with no gaps at all between the pixels. The only place I was aware of the EVF pixels were in diagonal strokes of letters on the various VF info readouts, or on the electronic level display, when the indicator lines were tilted. I never saw pixel jaggies when looking at the subjects I was shooting, even in the case of sharp high-contrast edges.

In salt water – which approximates human flesh, the skin depth at 1 MHz is actually 25 cm which means your arm is a pretty good conductor through and through. The illusion of safety comes from the fact that the frequency is too high for the nerves to react, so you don’t get spasms or cramps and you don’t feel the heating that’s happening below the skin because there’s no heat-sensing nerves there and those at the current entry points have died already.
