Things Your Electrician Wishes You Knew | Circuit Breaker Parts

The plug-in Kia Niro has an 8.9 kWh battery (vs. 1.6 kWh in the regular car). You can quickly estimate the amount of kWh you used in the week as long as the battery was fully drained every time you plugged the car in (it’s fully drained if the gasoline engine kicks in) and you know how many times you charged the car.

In the waning days of Flake’s presence in the Senate, the Arizona lawmaker, who’s frequently clashed with Trump, now has dwindling opportunities to make his mark. Longtime observers of his tortured reluctance to back Republicans going in a direction he does not like will recall that such stands often end with Flake simply, well, flaking.

The TLDR; is – “In high voltage systems clearance according to EN60065:1994, 3 mm is required for Class I and for Class II, 6 mm is required in mains operated systems (240VAC)”

Actually, some places (notably Australia and the UK) go to 240V, and this is +/- 10%, so theoretically you could be seeing anything up to 264V supplied. However, the supply companies seem to have a “better high than low” philosophy, and my UPS tells me I am currently receiving 257V on a 240V line. I actually believe the UPS, as I’ve regularly seen this happen with test equipment on the line.

The AVIC-W8400NEX flagship has a 7-inch capacitive touchscreen, while the AVIC-W6400NEX has a 6.2-inch capacitive touchscreen, and the AVH-W4400NEX has a 7-inch display with resistive touch capabilities. The receivers support both Google Assistant and Siri and can operate wirelessly via Bluetooth, Wi-Fi, or wired through a Lightning connection. Additionally, you can control your smart home devices through the units, including things like a garage door, locks, or lights.

The Death Star post illustrates why we shouldn’t let economists decide how to run things. That and a million other stories from real life.

These rules of thumb are referring to the amperage capacity or “ampacity” of the conductor (wire) and are often correct. Sometimes, these general rules lead technicians to believe that if an appliance is rated for 50-amp breaker/fuse maximum overcurrent circuit protector (MOCP), you must use 6-gauge wire and a 50-amp circuit breaker.

If you’re worried about activists using media to promote fear and doubt about science and medicine,you’re in the right place. At Science 2.0, scientists are the journalists. with no political bias or editorial control. But we can’t do it alone so please make a difference.

Your writing is appreciated. It’s good to learn something more than just the U.S. english terminology for things. Also makes for a better laugh (sometimes) at some of the anecdotes written in the comments that one reads in so many places online.

If you do not know the exact value of each cost, you could enter an estimated percentage based on the cost of goods.

If you look at the Fotek datasheet for that relay, you’ll find that the specified heatsink does not resemble a piece of galvanized steel sheet metal, horizontally mounted with a half inch air gap under it, and set on top of a heater.

You don’t need a big contactor to switch 1A at 120v, you can get little “ice cube” relays that switch up to 10A at 120V and they have a plug-in base so easy to change out when they inevitably fail. Most of them, in new perfect condition, make barely any sound. Nothing compared to the noise of fans and stepper motors. The only issue I can see is running AC mains voltage through wiring that is going in parallel with low voltage. Would need to use thick jacketed, shielded cable to prevent too much EMI. Maybe it’d be better suited using a separate transformer just for the heated bed, rectified/regulated but still a higher voltage for better efficiency. Speaking just from my experience as an electrician and hobbyist level electronics/3d printing experience.
