What Most Techs Get Wrong About Wire Sizing | 2017-09-18 | Circuit Breaker Parts
I don’t know where do you see low voltage traces close to mains voltage. Trace from R8 to the opto is 2.64. How far do you think it should be to meet your standards? Conformal coating is telling you anything? Bryan Orr is an HVAC and electrical contractor in Orlando, Florida. He is the founder of...Read more -
Could A Fire Have Caused The Loss Of MH370? | 25 Amp Circuit Breaker
When we moved from the UK about 15 years ago, we lived in a PME TN-S property and my ex neighbors house is still connected thus. Newbuild and current standard might be to try to retrospectively phase that out, but its still a generalization to say all properties will be TN-C connected. If your in...Read more -
How power works in a data center: What you need to know | 220v Contactor Relay
“OK, you hold that small bulb across that plug, I’ll connect this 9v battery across the live & neutral pins…” Yes, I get that there are societal differences between Eastern ideals and Western ideals. Please understand that Americans also build cheap crap, too- but being across an ocean makes ...Read more -
Pioneer debuts three new wireless CarPlay systems | 19mm Momentary Push Button
Everything else on the datasheet are useless observations only true under test conditions. A few really awesome datasheets give junction to ambient, which is a blessing if you don’t need a heatsink. 132KV is probably safer if you don’t test it with the back of your hand. It’s not like those littl...Read more -

Microsoft Edge for iOS and Android now comes with a built-in ad blocker | Lrd12 Overload Relay
At the risk of being labeled a pedant, I’ll remind you that Mike isn’t billed for power, he’s billed for energy, and you didn’t say how *long* you’d expect to draw 3 kW for free. Very interesting article. Being in the “treat it like radioactive anthrax” crowd, I rarely mess with mains level volta...Read more -
ZTE’s newest Blade phone features dual cameras, a glass back, and face detection | Lrd12 Overload Relay
Of course you can use an extra 50Hz transformer, you do not need voltage regulation. But you need power (DC) for motors and electronics. If you have already a switching PSU (which are often even cheaper than big heavy iron/copper transformers of the same power) the extra power capability for the ...Read more -
Does Tesla Make The Best Value EVSE For Non-Tesla Owners? | 220v Contactor Relay
