Does Tesla Make The Best Value EVSE For Non-Tesla Owners? | Lrd12 Overload Relay

by admin on 19-08-22

Best answer: Probably. The Amazon Smart Plug was designed to work with most any product you have in your home but there are some exceptions and devices that shouldn’t be connected. With 12/24V, the resistance is low enough that it can be done using copper traces on PCB. P=V^2/R, so the resi...

Yes, the Samsung Galaxy S9 has a headphone jack | 19mm Momentary Push Button

This is called Level 1 charging, and assuming you already have basic electric service in your garage, it’s the cheapest way to go. Unfortunately, it’s also the slowest. Depending on the vehicle and its battery capacity, it can take anywhere from eight to nearly 24 hours to bring its power cells u...

Inside A Circuit Breaker With MikesElectricStuff | Lrd12 Overload Relay

One possibility (on contactors) is to have a split pole with a copper ring one one half. This is similar to a shaded pole motor. The current which is induced in the copper ring (shorted winding) is out of phase with the current in the main winding and smooths out the zero crossings. Another possi...

Tom Baker is turning his long-lost Doctor Who movie script into a novel | 19mm Momentary Push Button

Rob, where would anyone ever get 10,000V from? Or even 1,000? Short of lightning strikes, these voltages don’t exist in the home, or in many factories. Why do those voltages matter? I probably ought to be dead, or have some scars at least, but apparently I’m a very resistant person. Any third-par...

A Short Guide to Vintage Traynor Amps | Circuit Breaker Parts

Pedantic FWIW: Afghanistan and North Korea and some banana nations use 110V. USA uses 120V/240V. Japan is the oddball, using 100V. Annoying because you can’t draw more than 1 kilowatt from a socket there (kettle, hair dryer, space heater…). And having lived with the three voltages (100V, 120V, 24...

How to Fix a Broken Air Conditioner | 220v Contactor Relay

by admin on 19-08-21

I do not claim infallibility. I invite criticism of my designs. But I insist on that criticism be based on my work rather than be mere FUD. Just curious, what size pump do you have? The Sonoff claims 10A per channel, but my 1HP pump needs a 40-50A relay to safely deal with cold-start current. Unl...

The Expanse is being turned into an RPG | 25 Amp Circuit Breaker

by admin on 19-08-21

However, DC distribution at the municipality level and smaller will be a nightmare to make work. Pretty much *everything* needs to be replaced, and for what purpose? It doesn’t really solve any significant problems and raises a host of others. Best answer: Probably. The Amazon Smart Plug was desi...

This robot uses AI to find Waldo, thereby ruining Where’s Waldo | Lrd12 Overload Relay

by admin on 19-08-21

Did you keep records so that you actually know you repaired 15,000 TVs? I don’t believe it, and if it is not true then I doubt your other statements on this evidence alone. People should classify their statements as to fact, fiction, or opinion, not just leave them in an ambiguous interpretive li...
