Nose Relief. The Sony A33′s viewfinder eyepiece projects back a bit, leaving a bit more room for your nose.
Most people posting seem to have three stories, I only have two. Hard to believe I learn faster than you all; I must have just forgotten the other times.
My own maxim is that just because something can be – and perhaps often is – done poorly or hazardously does not at all preclude any possibility that it can be done properly and safely.
This 225 percent of motor load/branch circuit allowance for breaker sizing is to allow for motor starting without nuisance trips while still providing circuit protection against short circuit conditions.
Depends how far north you are – direct sunlight isn’t required for them to produce useful heat. If you’ve got a months long night then they’re no use though.
The very first point to make clear when writing an article like this one is that you should disregard any ideas of “safe” voltages or currents. While the story about some significant number of people who die every year from licking a 9-volt battery is probably an urban legend and you have little to worry about from low voltage equipment, it is best to look at any higher voltages as potentially dangerous and react accordingly.
The triac can handle 8 amp continuously and upwards to 60 amps in surges. But the 8 amp is if heatsinked enough. If you insist on a 15 amp capability replace the triac with a 25-30 amp model instead. But will *still* need heatsinking. I triac usually drops upwards to 1 volt, so pushing 15 amps in a triac regardless of size will generate up to 15 watts, and that will generate a *lot* of head in a hurry.

I’ve paid 18’000.- CHF in Switzerland back in 2017 for a 9.3kW roof top installation and I’ve gotten 5’580.- CHF back from the Swiss government in cash. That’s like 13 cents per watt installed
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.
It is often a surprise to see how other people react to mains electricity when they encounter it in a piece of equipment. As engineers who have dealt with it both personally and professionally for many years it is easy to forget that not everyone has had that experience. On one hand we wince at those who dive in with no fear of the consequences, on the other we are constantly surprised at the number of people who treat any item with more than a few volts in it as though it was contaminated with radioactive anthrax and are scared to even think about opening it up.
