It’s the peak rating. For constant loads, or anything that could be temporarily constant you need to de-rate.

From the Auris to this, haven’t Toyota learnt anything. It’s just a slightly bigger and slightlly less DULL than the car it replaces.

For all my complaining about the difficulty of tracking sports subjects and the dead-screen issue, though, the difference between these SLTs and other consumer-level DSLRs is little short of astonishing. It may not be a direct substitute for a Canon 1D Mark IV or Nikon D3s, but if you have a budget of under $1,000 and shoot any fast action at all, the Sony A55 and A33 are hands-down slam-dunk purchase decisions. At this point, there’s nothing else in the large-sensor segment of the digital camera market that remotely approaches their high-speed capture capabilities.

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…..

One nice thing about the Sony A55 and A33′s electronic viewfinder is that the Fn menu is also available in the viewfinder display; you can make many camera settings without taking your eye from the viewfinder eyepiece. As I became more familiar with the camera’s controls, this led to a very efficient shooting style, although it would take more than the few days I’ve had with the camera thus far for this to become second nature.

But I don’t like the mains powered heater in this case: If you take 120W @24V its just 5A. No problem for a switching transistor or wires with 0,5mm² and you keep the mains voltage in the PSU box. Which I prefer in this case. Mains rated cabling (230V here in Europe) are not thinner and need thicker insulation. In the worst case you have to have PE connection to any metal part of the construction.

Storage and battery. The Sony Alpha A33 offers a single flash memory card slot, but it’s compatible with two memory card standards, each with various permutations. The first is Memory Stick PRO Duo / PRO-HG Duo, Sony’s own proprietary media format. As an alternative for those who prefer more standardized media, Sony also supports three flavors of Secure Digital cards — standard SD, SDHC, and SDXC.

• Pick your features: Models come with either a recoil handle (similar to a lawn mower) or electric push-button start, and one or more outlets to plug in extension cords. Some include covered outlets, illuminated control panels or automatic shutdown in case oil runs low. Portables can weigh from 100 to 250 pounds, so you’ll want to buy a wheel kit. With the wheels installed, a generator can be rolled like a wheelbarrow into place.

If I scan a ceiling and I find a cold spot that doesn’t make any sense, I dig into it. Maybe it’s a plumbing leak from above, or maybe it’s just a cold water line that’s touching the ceiling. That’s where a moisture meter comes in handy. Ok, I’m getting sidetracked. Let’s discuss some electrical examples.

There are of course odd exceptions: my grandmother’s old house from the 1920’s had an instant water heater. It was a single 415V element, connected between two phases. Highly unusual, and nearly killed an electrician who didn’t realise that one side of it wasn’t neutral.

I think most people recommend having the PSU switched off at the wall. That way it should be pretty much safe, but there is still the other issue you mention.

I adore the Gravity Blue finish on this tester — it’s a welcome change from the sea of grey, silver, and white that fills every damned parking lot. More blue/green here again.
