In San Diego (where I live) residential electricty rates start at 15 cents per kWh. Lower electric rates are available if you charge the car at night, but you have to agree to pay a crazy-high rate of 53 cents per kWh at other times. That wouldn’t work for me, but YMMV.

Yeah, dont use these. Use a relay instead. There is a reason all the high end stuff went away from the Triacs as they will float to full mains voltage when no load is connected and you get electrocuted when you mess with the circuit. AMX, Crestron, Lutron, etc all have moved away from pure Triac control due to this safety issue.

I was mainly thinking about the diff between high vs. low RMS AC voltage but the discussion of AC vs DC has been interesting as well.

Heck, as I said, when I have needed to do this in the past I just used a multimeter, a terminal block, and no relaying whatsoever (ah, being perhaps complacent “qualified personnel”, eh?)

At the risk of being labeled a pedant, I’ll remind you that Mike isn’t billed for power, he’s billed for energy, and you didn’t say how *long* you’d expect to draw 3 kW for free.

To tout that you’re rigorous about tracking efficiency data, you completely missed a very important statistic.

At the time I tried to get the regulatory authority in NSW to do something about it. Zero interest. Useless idiots.

I suppose I would’ve used small contactors with auxiliary contacts as interlocking instead through some sort of arrangement, but that’s only because I have a pile of them lying around (and you would just put the wires under terminals rather than QD’s) but as I said (and you reinforced) I trusted your QD’s, particularly at these…”small” levels of current.

Many of the Sony A55 and A33′s settings are accessed via the Fn button, just below and the to the left of the thumb grip recess on the back of the camera. I can’t think of any better place to put it, but accessing it does require loosening your grip, and therefore shifting support from your right hand to your left. Apart from that, the Fn button is in a good location, easy to find by feel: Just slide your thumb down out of its recess, and the Fn button is the first control you’ll touch.

Whether you call it neutral or ground is (I suppose) not important, what is important is that there is no distinction between neutral and ground until you are at the customer’s meter.

The Sony Alpha A33 lacks one feature found in the A55V (the only version of the A55 that’s sold in the US market) — a built-in GPS receiver. It’s still possible to geotag images and movies from the A33, but doing so will rely on an external GPS logging device and PC software that can backtrack to calculate the location at which images and movies were shot — not nearly as seamless a solution as the A55V’s ability to geotag images and movies straight out of the box.
