No, that’s not a typo in the fact box up top. I drove the Niro PHEV a total of 253.2 miles, and topped off the tank with 3.107 gallons of regular unleaded. 81.4934 miles to the gallon very nearly doubles the mileage I observed last year in the standard Niro. 26 miles of all-electric range makes a serious difference — there were many days where the gasoline engine never fired.

Oh, and if you want a car charging hack, there’s always the Hydra: http://hackaday.io/project/3939-j1772-hydra

What’s the big deal? The heated rock for my herpetarium plugs directly into the wall. Nice cozy and warm. No shocks for me, no limp lizard either.

Some customers get sticker shock, but I’m not trying to rip you off. You only see the half-hour of work I did in your home, but that’s not the whole story. I spent years training, and now I need to pay my crew (who went out of their way to get to your home), plus deal with marketing and other costs of running a business—and my prices reflect that.

what really matters is whether or not your insurance company will deny your claim. if you have homebrew stuff like this then you are wasting your money on homeowner’s insurance. and of course if your homeowners insurance is invalid then the bank will get a little upset about their mortgage

Wikipedia states most of mainland europe is on TN−S. “This arrangement is a current standard for most residential and industrial electric systems particularly in Europe”, if thats wrong, someone should fix it, preferably someone who has a authoritive position and can quote standards https://en.wikipedia.org/wiki/Earthing_system

The issue is we are more than willing to make unknown compromises for price. And we don’t just make these compromises with electronic components. We make the same compromises in the vehicles we drive, the foods we eat, the houses we buy…..

The only way, AFAIK, to know how much current it is actually supposed to be capable of is to calculate it based on the listed thermal resistance from junction to case, the thermal resistance of your heat sink from case to ambient, and the Rds(on).

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.

Many will ask what protects the circuit in an overload condition between the MCA and MOCP ratings? In these overload conditions, the overload protections on the motors themselves are designed to protect the circuit. If the overload protection on the compressor or fan motor fails, the windings in the motors have a far lower ampacity than the branch circuit and will fail open or shorted before the branch conductor will fail. In the case of any significant ground-fault short, the overcurrent protector (breaker or fuse) will still protect the circuit.
