How To Wire A New Garage For Electric-Car Charging: What You Need To Know | 25 Amp Circuit Breaker

No, ebay removed the ability for sellers to leave negative feedback years ago. Fun fact – the majority of an ebay sellers score these days (not the % positive feedback, but the score used for determining search rankings etc) is determined by the % of orders that are received on time and without a ebay ‘case’ (return, etc) being opened.

In some cases, contractors have stated that certain municipalities are requiring that conductors be sized based on the breaker size instead of the MCA. This is not uncommon, but it is usually a matter of a respectful conversation about the above NEC articles. The “authority having jurisdiction” or AHJ is responsible for interpreting the code, and they can make any standard they see fit. While certain local legislation may supersede the NEC with additional regulations, the NEC is a nationally recognized standard throughout the U.S. It is rare that a building department will ignore entire articles of the NEC when it is brought to their attention in a respectful manner.

Meh, just use a relay for your “PWM”. It’s much easier, and you have a huge low pass filter. You can easily go up to a few Hz switching with a good realy. Use a solid state relay and it’s even better (you might break your mechanical relay after prolonged use).

I don’t know, disassemble an induction heater, use the encased induction coil, feed it with mains, put a metal plate on it, and you got a safe but cumbersome heated bed using mains.

I use a variety of a/c and dc fostek ssrs. I have yet to have a problem, but i use them in circuits where 50% of their rated current is the absolute maximum they will ever see.

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.

Since the translucent mirror only reflects enough light to provide for the autofocus sensor, not an optical viewfinder as most pellicle designs permit, Sony has adopted full-time live view in the Alpha A33 and A55. In place of the optical viewfinder from a traditional SLR, the SLT cameras have an electronic viewfinder with 1,152,000 dot resolution. The EVF LCD is time-multiplexed — that is to say, it shows each color in sequence at every pixel location, rather than the separate, adjacent color dots of most electronic viewfinders. This makes it harder to distinguish individual pixels. The Sony SLT-series cameras also sport a wide-aspect 3-inch LCD with 921,600-dot resolution. Taking full advantage of the camera’s full-time live view shooting, the super-slim LCD tilts 180 degrees vertically, and swivels 270 degrees for easy viewing from most any angle. The cameras also include TruBlack technology borrowed from Sony’s picture frames.

For the person who jumps up and says “coatings insulate the water from the trace”, well no it doesn’t, we are talking about AC voltages and water that has formed over a large trace (even insulated) forms a capacitor that will conduct AC even when you have a DC insulation. Even if it did you then still have the exposed solder pads.

Probably doesn’t completely answer your question, but you might like to watch this for more info about RCD/RCBOs and how they operate. It contains some very entertaining explosions. }:~)

The ESD protective wrist strap should not tie you to a hard ground, it usually has a 1Meg resistor included, just for this reason. But perhaps not every cheap chinese one has?

Three electrocutions? Better be careful cat, you only have six more left before you will die for real Receiving an electrical shock isn’t an electrocution.

Oh, and I have fixed about 15,000 of the old CRT TV’s so while my mistakes can’t ever be called good, they’re not without precedent.
