We’ve seen very few car charging hacks. If you know of one, or have been working on your own, let us know!

While if we take the same supply and drive it with 300 volts DC, then it will only need a bit less then 4 amps. And this is in fact going to put our rectifier under less load then when we run it with 110 volts AC.

I am certainly not suggesting HVACR techs engage in performing work outside of their skills or licensures, but, in many cases, being able to identify the problem and making the repair are two different things.

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?

Several hot features were brought over from Sony’s NEX and Cyber-shot digital cameras, including Sweep Panorama, 3D Sweep Panorama, Auto High-Dynamic Range, and Handheld Twilight modes, each of which strategically combine and align several images into one seamless shot. It’s pretty impressive stuff. As if that weren’t enough, Sony has added an extra mode for the SLT-series cameras — Multi-Frame NR — which operates similarly to the handheld twilight mode, but allows the ISO sensitivity to be specified.

Nose Relief. The Sony A33′s viewfinder eyepiece projects back a bit, leaving a bit more room for your nose.

My Tesla Model 3 came a week ago, Thursday, and I traded in my Volt. So, I swapped out the NEMA L6-20, for an Eaton box with NEMA 14-50 receptacle, 8ft of 6-4 wire, and a 50 amp double-pole breaker. About $75 at Lowes. Yes, the Tesla came with a L2 EVSE that charges at 32 amps. You could buy the Tesla HPWC for $350, I think, but it’s totally not necessary for most.

In the case of Chinese relays and SSRs I double the amps and add 10% …. Ditto for Chinese switching regulators which put out everything but DC after they reach about 50-60% of their rated load

my first “real” job was in a video game arcade back in the 80’s my boss was a really cheap prick that used to buy asian cocktail machines that were “native” 110V, with a 240V to 110V step down transformer wedged in where it would fit, my second day I was fishing out a 20 cent coin that had missed the coin box, I got “zapped” hard enough to blow my finger nail in half and stop my heart.

The guy on final test stood on a rubber block but still used to get blown across the floor once a month

What about converting down to 12-24v AC for the bed with a ZVC switch going to the controller? It seems that running it off DC is wasteful but mains is relatively risky.

NEC article 440 was added because air conditioning and refrigeration systems are different from typical loads, like lights and heaters. Air conditioner compressor and fan motors are largely inductive (magnetic) loads and have different characteristics than purely resistive circuits. Article 440 has specific guidelines for HVAC and refrigeration equipment manufacturers to follow when writing the equipment data tags as well as for electricians when sizing conductors.
