What to Consider When Buying and Installing a Home Electric Vehicle Charging Station | 25 Amp Circuit Breaker

When we moved from the UK about 15 years ago, we lived in a PME TN-S property and my ex neighbors house is still connected thus. Newbuild and current standard might be to try to retrospectively phase that out, but its still a generalization to say all properties will be TN-C connected. If your in a TN-S property, its my understanding that ignoring that layout and putting your own earthing system in and bonding it to the supply one, can result in ground current back flowing through your system from neighboring properties.

One of the best demonstrations I’ve ever seen, was at the Dayton hamvention. DP&L (Dayton Power & Light) set up several short poles with standard 7200 to 220 center tap transformers. By back feeding the secondaries with 220 from the breaker box, they could energize the 7200 lines and began demonstration what happens when you encounter these wires with numerous items. Antenna masts, kite strings, and even a hot dog were used to show the immense power available, and the audience was always suitably impressed.

I like the idea, but you don’t need a 3D printer for this. Just use conductive strips or good ol’ fashioned wire.

In my experiences, TRIACs fail shorted more often than explode. We have a failsafe of cutting off a mechanical relay in case it happens. Exploded TRIACs do happen though, in the rare case when the load has high leakage to earth, which we don’t have ground fault detection on our devices at the moment. TRIAC we use is rated for 40AMPS @ 600V though for industrial temperature control applications.

I’m glad you are aware of all of the many issues surrounding this kind of a hack. I spent 15 years as a commercial electrician, so the first thing that I did when I started to read this was think, “Oh, crap. Someone’s going to kill themselves.” I’m glad that’s not the case here.

Yes, unfortunately, in my house the car isn’t in the basement. I work cheaper than most electricians, but nowadays they hardly do anything for $300. My Neighbor across the street paid for a 1/3 hp 110 volt outlet for his pool mandated by the town to be installed by a licensed electrician in this town, and it cost him $1400 for a simple direct buried UF 14-2 cable and a faceless ground fault on a dedicated 15 ampere circuit. That was more than the pool and filter. It would have been $1500 but he saved $100 by digging the trench himself..

You say dull, I say perfectly judged for the day to day. This plus a sports car for the weekend would be a very nice combo.

I’ve left perhaps the most salient characteristic of the Sony AF55 and A33′s EVF till last: It’s huge. The view through the Sony A33′s eyepiece is much more akin to that of a full-frame DSLR than that of any competing sub-frame model currently on the market. It manages this with a comfortably high eye point (and plenty of dioptric adjustment) for eyeglass wearers, at least when simply viewing the live viewfinder image itself.

Yeah really though. It’s kind of embarrassing. I’m an engineer and work in big industry (usually minerals, bulk material handling, oil and gas, doing a big robotics project right now for a wood products plant, etc.) and this would be an afterthought. No one would even question it. I mean really a no brainer. People use electric blankets on their bed. I really don’t get it. It really shows how amateur hour most of the people who comment on this site are.

Redpepper’s video description boasts: “While only a prototype, the fastest There’s Waldo has pointed out a match has been 4.45 seconds which is better than most 5 year olds.” If this is a competition, we really can’t win against the machines.

Might be safer your way, since you’re transforming down, then back up again. Using a microwave oven transformer means horribly high voltages in the middle of the thing, and should, by chance, some insulation fail, or a bit of an arc, or whatever…

It’s a Prius for private buyers. It’s got one of the best drivetrains and most sophisticated chassis in the class, looks ok inside and out, no doubt usual exemplary quality and reliability.
