Charging Your Tesla Model 3 With Just A Wall Outlet | 19mm Momentary Push Button

It should be possible. I used to have a heated tray for keeping my home brew beer and wine warm while fermenting. It was probably only about 30 degrees C but mains voltage.

And you’d need to think about seperation (diodes to seperate the two paths?) if you wanted to read a local button press verses a node press, or would you be better off just doing that in software. Detecting a button press and checking to see if the node had recently issued one itself.

Not at all. One lumberjack pushes while the other pulls, and they’re both pushing and pulling against the ground. It’s fits perfectly.

Two inputs for the beefy converter are supplied from outlets not just on separate circuits, but on two circuits whose hot lines are 180 degrees out of phase. That means identifying where there are two plugs, not protected by GFCI outlets or breakers, which are on two separate hot lines of split phase power. To protect the user, [Nick] designed in a set of relays which kill the circuit when one of the two supplies is unplugged. A system that didn’t have these protections would have mains voltage on the prongs of the disconnected plug.

NEW YORK (AP) — Wells Fargo will pay $575 million in a settlement with attorneys general from all 50 states…

So a 20 amp breaker is designed to take the load shift on startup. A 15 amp breaker will carry the nominal load, but that surge on startup will kick it every time. In the days before switching supplies the input voltage would vary from 108 to 115VAC where I did work. This occasionally caused breaker trips on the unprepared circuit. I learned to spec high enough to minimize that issue and keep a safety factor in play.

If the car achieved its minimum 44 mpg and used 3.1 gallons, that means 136 miles were done on gasoline and 117 were EV miles.

My grandmother had a set of glass topped buffet serving tables where the glass top had a foil element sandwiched between the glass layers. They plugged right into the wall. No components other than the heating element, line cord, and a neon bulb to remind you it was plugged in. The element terminated with a couple of fused in copper rods threaded to take nuts. Got too hot to comfortably touch, but warm enough to keep your food hot. It should be within the capabilities of a glass/ceramics hobbiest with a kiln to sandwich a foil element between two pieces of glass and fuse the sandwich together.

My post outlines the PME system. There are older systems that do run an earth / ground but they are being removed as and when they need attention. The US system is different but the number of countries using the US system is much less than the number of countries that use a similar system to the UK. I am UK based and UK trained.

I am not going to go right into the above calculations as there are plenty of graphs and tables out the on the net that you can google for. Example – http://electronics.stackexchange.com/questions/22796/creepage-distance-for-pcbs-handling-line-voltage-ac, http://www.smps.us/pcbtracespacing.html

I’m renovating my basement, and putting in a 240V line to my garage. Just for something to do, as I don’t have an EV.

The gate resistor will eventually short to the trace after so many cycles. It may take a while, but it will eventually happen. We had that problem years ago with a product. Resistor has to be lifted up above the trace. Traces and such seem fine for 120VAC for low current loads. Wouldn’t pass muster overseas.
