Looking Mains Voltage In The Eye And Surviving | Lrd12 Overload Relay

I haven’t seen you around the traps here before and you have put in a good effort so welcome aboard.

However, experience tells me that this very minimal standard is not good practice. Modelling for 240V will only cause problems with the first over voltage transient or spike.

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…

Anyone know a good source of information for dummies on electromagnet math? I’d love to build one of those electro magnetic pan brakes, but blindly connecting 240VAC to a coil scares me.

Xiaomi has announced the Mi Mix 3, the latest entry in its series of full-screen flagship phones. It’s yet another high-end Chinese device with a huge screen-to-body ratio achieved by hiding the front-facing cameras on a sliding mechanism — no notch required. Unlike the Vivo Nex or Oppo Find X, however, the slider isn’t powered by motors. CEO Lei Jun compares the design to older sliding phones and suggests that it’ll be relaxing just to play with.

Gasoline-powered portable generators, which cost from about $400 to $1,500, based on their output and features, are not only readily available at home-improvement stores, they’re easy to use. “If you can operate a lawn mower, you can operate a generator,” says Art Aiello, spokesman for Generac, one of the largest manufacturers of portable generators. “In winter, it doesn’t take a lot of snow or ice to bring down a power line in certain neighborhoods. If you have the ability to pull it out, add fuel and attach extension cords, a portable is a sound solution.”

Just reach for the “Flame Wrench” while working on a press, in a corrugated box plant. Within the next two minutes, you’ll know how many fire extinguishers are in that building. Box dust and the old, grease based, Letterpress ink was always a major concern when you were doing the repairs and needed to use a grinder, torch or welder, etc..

When I’m doing electrical work, I *always* short the conductors to verify no power (after flipping the breaker and testing with a meter). Better safe than sorry.

Wrong again – The VOLT from the very first had a choice of 8 or 12 – it just wasn’t from the touch screen in the car in the first 2 years, it was a button on their ‘charger cord’. And there was no ‘default’. Unlike later cars such as my ELR and BOLT that must be constantly changed to 12 amps on L1 (yes, I know about zip code based charging on the bolt), my 2011 VOLT would stay at the setting you left it at since it was stored in the EVSE, NOT the car.

All electrical devices are designed with safety in mind and are rigorously tested to make sure the design works. All of us have probably plugged in one too many things on the same circuit and tripped a breaker or blown a fuse, and that’s the first consideration you need to know about the Amazon Smart Plug — it has a safe output rating based on the type of load you’re using. Here are the exact technical specifications according to Amazon.
