Portable 120V to 240V Converter; or How to Fast Charge at Your In-Law’s House | Lrd12 Overload Relay

MOVs are rated for specific ac-line operating voltages. Exceeding these limits by applying a sustained abnormal overvoltage condition could result in overheating and damage to the MOV.

Knocking over a candle would be an accident. Keeping barrels of petrol in your living room would be negligence. Doing your own mains wiring without the proper qualifications, I dunno which side that falls on. Real accidents can’t be foreseen, but you have to take reasonable precautions.

Hey [Martin] I think you deserve some recognition for your contribution here tonight (or whatever time it is for you).

440.22 Application and Selection (A) Rating or Setting for Individual Motor-Compressors — The motor compressor branch-circuit short-circuit and ground-fault protective device shall be capable of carrying the starting current of the motor. A protective device having a rating or setting not exceeding 175 percent of the motor compressor’s rated-load current or branch-circuit selection current, whichever is greater, shall be permitted, provided that, where the protection specified is not sufficient for the starting current of the motor, the rating or setting shall be permitted to be increased but shall not exceed 225 percent of the motor rated-load current or branch-circuit selection current, whichever is greater.

A lot of info: The Sony A33′s EVF display conveys loads of info, but the Fn menu items (shown here at the left and right edge) require a low eyepoint or eye movement to take in. (Image courtesy Sony USA.)

From the top of the Sony Alpha A33 camera body, you can just see the stereo microphones, located on either side of the flash hot shoe on the sides of the viewfinder / popup flash housing, as well as the three hole grille the speaker (above the Finder/LCD button). At the top of the handgrip is the popular combination of a shutter button surrounded by a power switch, making it easy to quickly power on the camera and snap a picture with one finger. The Finder / LCD button allows the A33 to be manually switched between shooting with the electronic viewfinder or the rear LCD panel. Upper right of this is a D-Range button that provides access to Dynamic Range Optimizer and High Dynamic Range shooting options.

This doesn’t make any sense, why not use an extension cord with the 220 already in the house? A 6 or 8 gauge cord for 75 feet should be perfectly fine.

There’s one more multi-shot feature on the Sony A33 that’s worth mentioning; namely Auto HDR (High Dynamic Range). HDR photography increases the range of brightness values represented in a scene by combining two or more shots taken at different exposures, combining highlight detail from some and shadow detail from others. In the past, this has involved locking the camera down on a tripod, shooting several images at different exposures, and then working on a computer to combine them. Lately, though, the capability to do this directly in-camera has been appearing from a number of manufacturers, with varying levels of success. The auto HDR feature on the Sony A33 works pretty well, since the camera does the same micro-alignment trick it uses for its other multi-shot features. Options for HDR include an Auto setting, where the camera determines how much of the effect to apply, and manual settings ranging from 1 to 6(!) EV of exposure range.

Just three months after launching the NEX-3 and NEX-5 single-lens direct-view (SLD) cameras, Sony offers up yet another interchangeable lens alternative to the traditional DSLR, with the Alpha SLT-A33, and its closely-related sibling the SLT-A55. Instead of being mirrorless, the new digital cameras employ a "translucent mirror," more commonly known as a pellicle mirror. This advanced translucent mirror remains fixed in place during operation, allowing most of the light to reach the imaging sensor, while a small percentage is reflected to a dedicated autofocus sensor.
