Constellation Performance Centaur II 500 power amplifier | Circuit Breaker Parts

The customer changed their tune. My boss was impressed (though not enough to give me some coinage for ingenuity) and the electrician was told to change the breakers and add the new feeders to support the load. Got a lot of recommendations from that customer in the years after that.

Due to its diminutive stature, most photographers will find that the grip only accommodates two fingers, with the index finger resting on the shutter release button above, and the little finger curling beneath the bottom of the camera. This might seem a little crowded, but with the light, plastic-bodied 18-55mm kit lens, handling is nonetheless good, with the combination feeling extremely well balanced. Using larger, heavier lenses, the grip size is too tiring for single-handed shooting, so the photographer’s left hand will need to serve double duty, adjusting zoom or focus while simultaneously taking up the weight of the lens itself.

Many thermostats are battery-operated, and once they power down so will your air conditioner or heater. Check that your thermostat is fully operational and the connections to the wall are good.

It’s good to see a snubber on the design (that’s often omitted on DIY designs I’ve seen). There are a few TRIACs that are designed to commute highly-inductive loads (“snubberless” is the marketing term I’ve seen) — may worth looking into them to reduce the BOM.

VAC says: “The two 120V legs are *in phase* with each other.” Of course they are not. *by definition* if they were in phase there would be no voltage difference between them. The two 120V legs are 180 degrees different from each other, so the difference between them is 240V. Which is (of course) the supply voltage.

Ive had a few shocks off 220vac but nothing that hospitalized me. But I do distinctly remember a shock recieved by a friend. He had a illegal cb with a zetagi 1kw valve linear amp, it tended to carbon up its changeover contacts and loose quality on ssb so I showed him how to turn it off, isolate it, drain it down and clean them up with contact cleaner. And I kept repeatedly stressing, dont do this without doing the whole isolation things as it will kill otherwise. Well, one day it went bad in the middle of a qso, and this was to some prized russian area, so throwing caution to the wind, he sprays contact cleaner at the relay while mid conversation, while holding a aluminium microphone in other end to talk it up. You guessed it, the valve hv field collapsed into the stream of contact cleaner, threw him across the room and into a wall and his glasses were blown off and twisted by the event. His girlfriend took him to hospital and it took a fortnight before they were happy with his vital signs to declare him fit to leave. All I could say when I visited him was “I bloody told you so” but his girlfriend was up for blaming me “for showing him”, and since then I’ve shied away from showing people things that if they ignore some of my warnings could kill them.

Mains powered heated glass plates are common place in catering, same deal as a car back window, the heating wires are on the other side from the “working surface” these things can tolerate touching and even fluid spills, why reinvent the wheel, the solution is already commercially avaliable.

• Find some space: Although you can store a portable generator in a garage or shed, it must be at least 20 feet away from your home when running because it produces carbon monoxide. You may be glad it’s 20 feet away, because portable generators can be obnoxiously noisy. (This may not please your neighbors, however.)

All silly, make graphene in a blender combine it with acrylic paint, then paint it on. Making heated beds is anything but an art form. Or just use graphite.

These were obviously mistakes. I would never intentionally come into contact with HT from the anode cap.

All electrical devices are designed with safety in mind and are rigorously tested to make sure the design works. All of us have probably plugged in one too many things on the same circuit and tripped a breaker or blown a fuse, and that’s the first consideration you need to know about the Amazon Smart Plug — it has a safe output rating based on the type of load you’re using. Here are the exact technical specifications according to Amazon.
