How To Wire A New Garage For Electric-Car Charging: What You Need To Know | 19mm Momentary Push Button

Isn’t welding the core kind of a bad idea as it will short the laminated plates and make it heat a lot?

For example, you can assemble a computer and do anything you want with the low-voltage parts, but opening the PSU and fiddling with that is illegal in many parts of the world. IF the device later catches fire and the insurance company finds out it was modified by yours truly, they can deny coverage, and if your neighbor’s house burns along with yours they can sue you etc. etc.

I’m wondering why nobody is simply rectifying a 120vac input for dc wiring the secondary coil? It means you don’t have to swap the coil location or use a dc power supply. I have a trans with a secondary resistance of 82ohms. Putting 120vdc through it would be about 175watts (assuming I do a good job of determining wire size and 1.46amps is ok)

How are you implementing the power calculations, out of curiosity? (I have designed a couple of AC power meters before, so it’s somewhat of an interest of mine)

I have seen a 10cm hole blown right through the middle of circuit board. I have had many repair jobs that it’s been obvious that lightning has hit the overhead power lines, exploded parts, vaporised PCB traces. Non of these had any negative outcomes except having to repair the device or throwing it in the bin, generally the latter.

This plate is too likely to touch the user. It’s sensible to have a certain fear of mains voltages, makes you pay attention when you’re working with it. The DC power suggested would come from the printer’s existing PSU, pay a little bit extra for a few more amps, the overall wattage isn’t high. Much less than I presume you’d use in industry. Thanks to power-hungry graphics cards, high-power PC PSUs are cheap.

This isn’t the first occasion that Flake has threatened to withhold his support for judicial nominees. He did something similar before to prompt consideration of a measure on tariffs, though he ultimately relented after the Senate voted on a purely symbolic effort.

Over and over again, I have heard HVACR technicians and electricians quote rules of thumb regarding wiring sizing, and I have witnessed and participated in many heated debates on the topic.

In some places, you can get 120 and 240, or you could wire up a large transformer at your mains distribution board and get what ever voltage you wish. Might need to call the local electrician to not loose any legal battles if the house burns down.

When a circuit breaker has a lot of current flowing through it, it will get warm. The warm 15-amp circuit breaker shown below had a 15.6-amp hair dryer running for about 20 minutes, and it warmed up to about 17 degrees over ambient. It wasn’t especially hot, but it was definitely overloaded.

I know this goes against what many of you have been told and understood your entire career, but take a deep breath and read on.
