Motor Nameplate Current vs. NEC Full Load Current Values | National Electrical Code | 25 Amp Circuit Breaker
*My* electricity is cheap (~$0.065/kW), so that 117 miles would cost about $7.61. Gas in my area is down to about $2.70/gallon, so the total fuel cost for those 253 miles would be about $16. Other areas of the country might be higher for electricity and lower for gas. For maximum resolution and s...Read more -
This robot uses AI to find Waldo, thereby ruining Where’s Waldo | Circuit Breaker Parts
ead of single layer traces covered by the paint, what about multilayer PCB? So the traces would be embedded between two FR4. This way it would be safer. That. Console. Is. Disgusting. Reminds me of my PT Cruiserâs cheapest part: the single piece off-white console. The car can accept up to 48 am...Read more -
Pioneer debuts three new wireless CarPlay systems | 25 Amp Circuit Breaker
This hack is ridiculous and a hazard. The NEC bans the use of MWBC’s that don’t use a common circuit breaker tie-bar. The tie-bar causes both halves of the 240VAC circuit to turn off incase of an overcurrent condition. An emergency isolation switch. Santeri Viinamäki [CC BY 3.0], via Wikimedia Co...Read more -
AFCI circuit breakers and the problem of ‘nuisance tripping’ | 19mm Momentary Push Button
Although a mains powered heated bed sounds scary for a hobbyist-built 3D printer, there are a number of positives to the design. It would heat up faster, thin down a few parts, and significantly reduce the overall cost of the printer by not requiring another 100 Watts delivered from a 12V power s...Read more -
Turn a wall outlet into a wireless charger with the Legrand Radiant | 25 Amp Circuit Breaker
Very interesting article. Being in the “treat it like radioactive anthrax” crowd, I rarely mess with mains level voltage, but I got a peek at what is required to do so. I read the paragraph about the “residual current circuit breaker” and thought it sounded very much like a GFCI (Ground Fault Cir...Read more -
Sega pushes the Mega Drive Mini global release to 2019 | 19mm Momentary Push Button
The skin depth varies with the magnetic permeability of the material. Iron for example reacts at very low frequencies, so much so that it becomes useless for wires at 50 Hz. 2. It’s very likely that this device will need to be used with extension cords in order to find two GFCI-free outlets in di...Read more -
Motor Nameplate Current vs. NEC Full Load Current Values | National Electrical Code | 25 Amp Circuit Breaker
A good quality EVSE can cost between $300 and around $1,200. If you’re choosing a wall-mounted unit, expect to pay another several hundred dollars for installation, depending on local labor rates and permit costs. Just three months after launching the NEX-3 and NEX-5 single-lens direct-view (SLD)...Read more -
Looking Mains Voltage In The Eye And Surviving | Lrd12 Overload Relay
Not always, you have to think on a global scope here before saying generalizations! In the UK a lot of houses are on what they call PME or protected multiple earths, where the earth bond goes back to the substation as a extra conductor. If you are in one of these properties and are not aware of i...Read more
