Thanks for letting me know about the typo and qualifier on the 208V part. I’ve updated it in the article.

Life gets in the way. No matter how much you plan, there will always be circumstances that, at the very least, interfere with that plan — if not throw it completely out the window.

Specs-wise, the Mi Mix 3 moves the series to OLED with a 6.4-inch 1080p panel. There are four cameras in total: 12-megapixel wide-angle and telephoto modules on the back, and a 24-megapixel selfie camera backed by a 2-megapixel sensor on the front. The phone has a fingerprint sensor on the back, so unlike the Oppo Find X you don’t have to pop the cameras up every time you want to unlock it.

My first thought was that the terminals were over torqued rotating the blocks, stretching the pins, and tearing the pads.

I don’t know about anywhere else, but in North America, power enters the home via two 120V hot and one neutral. The two 120V hot legs are out of phase with each other, and when combined, you get 240V. So, from the breaker panel, you can pull 120V or 240V, depending on the type of breaker you insert at a given position. Some large appliances (water heaters, central AC units, electric stoves, large power tools) are 240V in North America, but most everything else is designed for a single leg 120V feed. Then just to make things even more complicated, large industrial businesses often have three phase 480V for the really big equipment.

For every piece of equipment that lists MOCP and MCA, you are given the breaker size and minimum wire ampacity. As above, the MOCP is usually significantly higher than the MCA, but this is to allow for the spike in amp draw upon motor start.

The Sony A33 ships in the US market from mid-October 2010, with pricing of US$750 for the camera body and an 18-55mm kit lens, or $650 for the body only package.

It should be mentioned that any of us that have been working in commercial/industrial settings should be familiar and certified under NFPA70E. This includes, but is not limited to, how to work as safe as possible with hazardous energy sources, what the proper protection is for various levels and what is considered “safe” (working distance, approach distance, protection level, etc).

Over and over again, I have heard HVACR technicians and electricians quote rules of thumb regarding wiring sizing, and I have witnessed and participated in many heated debates on the topic.

“AC is safer than DC. You can let go of two AC terminals but not DC as DC keeps your muscles clenched. AC doesn’t. ”

Earthing is thus a vital part of power distribution safety. The only snag with open equipment on your bench is that any earth connection becomes a valid part of the return circuit for the power, and since that earth connection can come through you, that’s dangerous. The isolating transformer breaks that earth circuit for your bench, thus removing that particular hazard. The upshot of this is that you can safely touch either one of the two wires and because there’s no path to ground, you won’t get zapped. (Touching two wires completes the circuit. You still have to be careful!) Isolation transformers are also used to lift the ground so that you can connect mains circuitry up to your oscilloscope, even though the black probe clip is connected to earth ground.
