It’s probably worth at this point explaining for a minute how earthing works with respect to mains power. You will have a local earth connection at your house, and your utility company will connect the neutral line to an earth at the substation to ensure that line voltages are not induced at a higher voltage with respect to their surroundings than the voltage they are supposed to carry. There may be 110V or 230V between the live and the neutral depending where you live, but without that earth connection both of those conductors could end up at thousands of volts higher than their surroundings, for example in a thunderstorm. The earth connection provides a fixed relationship between line voltage and the surroundings, such as the utility poles, trees, your house, and you.
Need the gas for the generator, or the ELR during emergencies. Usually just use the bolt and elr for home juice during power failures. I answer the lawnmower comment after they approve the moderation.
Voltage TransientsVaristors feature high durability, which is essential for withstanding repeated high-peak pulse currents and high-energy surge transients. They also offer a wide voltage range, high energy absorption, and fast response to voltage transients. Peak current ratings range from 20 to 70,000 A, while peak energy ratings range from 0.01 to 10, 000 J.
Image sensor and processor. Of course, the image sensor and processor are also an important part of the speed and image quality of the Sony A33. The Sony SLT-A33 has a newly developed Exmor APS HD CMOS sensor, which has a total resolution of 14.6 megapixels, and an effective resolution of 14.2 megapixels. That’s just slightly below the 16.7 megapixel total resolution of the A55, which yields its effective resolution of 16.2 megapixels.
Several hot features were brought over from Sony’s NEX and Cyber-shot digital cameras, including Sweep Panorama, 3D Sweep Panorama, Auto High-Dynamic Range, and Handheld Twilight modes, each of which strategically combine and align several images into one seamless shot. It’s pretty impressive stuff. As if that weren’t enough, Sony has added an extra mode for the SLT-series cameras — Multi-Frame NR — which operates similarly to the handheld twilight mode, but allows the ISO sensitivity to be specified.
On our case a combo was the right solution. We use a contactor (a relay) to switch incoming power because it’s either on or off. But we use a SSR to switch elements on and off because they cycle on/off many times a minute.
Wrong again – The VOLT from the very first had a choice of 8 or 12 – it just wasn’t from the touch screen in the car in the first 2 years, it was a button on their ‘charger cord’. And there was no ‘default’. Unlike later cars such as my ELR and BOLT that must be constantly changed to 12 amps on L1 (yes, I know about zip code based charging on the bolt), my 2011 VOLT would stay at the setting you left it at since it was stored in the EVSE, NOT the car.
But yes, 1A is the absolute maximum, peak value for the MOC3041M for a brief amount of time. Even the MOC3041’s 8A maximum, temporary rating is unsuitable as a peak for a typical 15A US mains.
Didn’t have to purchase any EVSE. My 2016 Volt came with one, that was L2 capable. You only needed to make a pigtail. It’s actually a Clipper Creek. So, for about $60, I installed a NEMA L6-20 outlet, with 20amp double-pole breaker, and 8 ft of 10-4 wire that I had left over. $20 got me a permit.
And you’d need to think about seperation (diodes to seperate the two paths?) if you wanted to read a local button press verses a node press, or would you be better off just doing that in software. Detecting a button press and checking to see if the node had recently issued one itself.
No, because they are opposite phase. In this setup the neutral wire doesn’t carry any current, so the same 15 amps goes through both hot wires.
The device uses two hot and one ground to supply the 240V output which is, in some business where there is three phase power this will be closer to 208V but should still work. Obviously you shouldn’t be doing this unless you know exactly how it works, and we applaud [Nick] for airing these hazards while at the same time supplying the knowledge behind the concerns.
