What to Consider When Buying and Installing a Home Electric Vehicle Charging Station | Lrd12 Overload Relay

The outlet on your wall is likely on a 15 amp circuit, so in many cases, the Smart Plug can handle as much power as the breaker or fuse can. To see what the power requirements of many electrical devices are and what type of load they create, you should visit Electrical Safety First. It’s a site based out of the UK, but the power ratings for products are the same no matter which country you use them in and the charts here are an invaluable tool.

I can’t remember the exact numbers, but before the change, UK mains voltage was acceptable between something like 210V and 270V, depending on grid load. EU mains had a similar range. All they did, was tighten up the range. So now it’s nominally 230V, with 240V being within acceptable range. Which is good because the voltage stayed exactly the same. They just trimmed the range at the top end to be within the EU standards.

True enough; This hack goes back decades floor finishers who have large floor sanders use this hack to run their large sanders.

The varistor’s absorption of the transient energy during a surge event produces localized heating within the component, which eventually leads to its degradation. If left unprotected, the degradation of a varistor can increase heating and thermal runaway. As such, a growing number of varistor-based surge-protection devices offer a built-in thermal disconnect function. It provides added protection from catastrophic failures and fire hazards, even under extreme circumstances of varistor end-of-life or sustained overvoltage.

3-phase installations like industrial facilities and some apartments are fed with 208V 3-phase, which provide three phases of 120V to neutral, or 208V phase-to-phase.

PS I understand L1 will work for many people (up to maybe 40 miles per day driving), I disagree that it should be encouraged due to safety concerns and most general people won’t properly care for the L1 charger.

The real problem with mains voltages is that somewhere, some day, some bonehead will manage to fry himself – and the media will blame the maker movement for it. I’ve already seen far too many absolute beginners planning to wire up their home appliances to an Arduino as their first project…

Thank you so much for posting this! One tiny correction: the “108V” reference should be 208V, and that applies only in business settings where three phase power is supplied to the building. In that case, the three phases are 120 degrees apart, resulting in any two yielding 208 volts. Residential split-phase service will 180 degrees out oh phase, resulting in 240V.

“International” power supplies usually are specified for 100V (Japan) to 240V +/- 10%, i.e., 90-264V.

Samsung is rolling out an update for its 2018 lineup of QLED TVs that enables FreeSync, which allows for smoother gaming without screen tearing. The company talked up its partnership with Microsoft’s Xbox division during its unveiling of this year’s sets, and this is yet another feature that embraces the capabilities of the Xbox One X.

Senate Majority Leader Mitch McConnell has been clear that, aside from any spending bills, Republicans’ priority for the end of the year is to keep pushing judges through — and if Flake holds on this issue, it could throw a wrench into that plan.

Kapton tape is nice but I know it peels and needs replacing eventually. You wouldn’t legally be able to sell something using just tape as a mains insulator. Glass can break. It’s a small chance, but risk should be proportionate to the danger when things fail. You might sometimes have metal screws or whatnot on the bed if you’re assembling a couple of pieces there. Best not to mess.
