Rob, where would anyone ever get 10,000V from? Or even 1,000? Short of lightning strikes, these voltages don’t exist in the home, or in many factories. Why do those voltages matter?

people remember “the good old days” and they forget all about the horrible accidents and fires and massive death that came from ignoring fire regulations

A user calling himself "Tango" over at the MyNissanLEAF forum posted them yesterday saying, "I wasn’t sure if anyone posted pics of the insides yet, so while they were [installing it], I took a couple of pictures of the innards."

Great reasons to add L2 to your own garage, carport, parking spot: preconditioning vehicle will not reduce your SOC, lower fire risk than overloading an existing 120V circuit, more efficient charging, added resale value to your house, NEMA 14-50 outlet can be used for other things (welder, RV, heater, etc.), two EVs in the same garage, maximize off-peak charging, cool factor, etc.

I don’t know if the heat is high enough but mirror heating pads can be quite small and put under a sheet of glass would be quite effective.

Terminals 4 and 6 are used for capacitors and/or condenser fan connections and have no electrical significance to the starting relay itself, as shown in Figure 1. In fact, terminals 4 and 6 are sometimes referred to as “dummy” terminals and are simply used for wire connections.Figure 2 shows how a potential relay is wired to a capacitor-start/capacitor-run compressor motor. Notice that the relay coil is wired in parallel with the start winding and the start capacitor.

But don’t believe brand names are any better, especially if you buy them from eBay or Amazon! There is too much profit to be made remarking parts to trust any of these type parts from anyone but a major distributor like DIGIKEY or MOUSER Electronics.

Exactly, sometimes less of a compact form factor makes a better product overall. Snubber circuit is a nice touch tough.

I think it’s just fine and nice to see someone put care and thinking into this sort of thing in an unusual way for HaD. Usually people are either completely terrified or entirely cavalier about mains voltage in projects on here when all that is required is some respect and thoughtfulness like you have quite obviously displayed. Next you can add a power meter so you know how many quarters to give your friend

Good call, light bulbs and heating elements don’t need perfect smooth precise 12vDC, as long as it’s in the ball park you’re good.

We drive about 30k miles/year, lots of long trips. After a trip, we usually pull in with 25-50 miles of range remaining. No problem – charging to the normal 80% is < 7 hours.
