440.32 Single Motor-Compressor — Branch-circuit conductors supplying a single-motor compressor shall have an ampacity not less than 125 percent of either the motor compressor-rated load current or the branch-circuit selection current, whichever is greater.

Lenovo is promising 30 percent better performance over its previous Miix 630 Windows on ARM device, and a surprising claim of 25 hours of battery life to match. While the battery life sounds impressive, it’s the performance that will matter in a device like this and we’ll need to test this latest range of ARM-powered laptops to see if app compatibility and performance has improved. Most Windows desktop apps will run emulated on these ARM-powered devices, but there are some limitations. As this is powered by the Snapdragon 850, there’s also built-in LTE support for mobile connectivity on the go.

A properly wired, properly functioning dimmer switch can get hot to the touch. I’ve found that a 65-degree temperature rise is normal for a maxed-out dimmer. If the ambient temperature is 71 degrees and a dimmer switch is at 136 degrees, I’d be concerned, but I wouldn’t report the temperature as a problem. I would, however, take an extra minute or two to figure out how many watts the dimmer is rated for. I’d then make sure there wasn’t too much being controlled by the dimmer.

While we are on this topic, in Canada a common building distribution voltage is 347/600V. Typically supplied to any medium sized business that requires more than 100kW and less than what would justify their own high voltage vault. For you electricians out there, a neat trick with 347/600V is that the current on a balanced 3 phase line nicely multiplies out to the power. So at 3 lines x 347V at 100A is 104kVA.

3-phase installations like industrial facilities and some apartments are fed with 208V 3-phase, which provide three phases of 120V to neutral, or 208V phase-to-phase.

Dust reduction. The Sony A33 has a dust abatement and removal system. A charge-protection coating on the low-pass filter aims to prevent dust adhering in the first place. The sensor shift mechanism used to provide SteadyShot image stabilization also doubles as a shake mechanism to try and free stubborn dust particles that settle on the low-pass filter, although at much lower frequencies than the vibration induced by cameras using a piezoelectric element. From what we can tell, there is no strategy for keeping dust off the translucent mirror, except to blow the surface gently with air; it cannot be cleaned, and should never be touched. A fingerprint would require replacement at a service center.

Our heat pump works in conjunction with a gas furnace for the days when it drops below maybe 35f outside

Electric blankets have lots of testing to ensure they’re safely insulated from the user. They also don’t get nearly as hot. They also use too much power to economically run from a low voltage PSU.

The triac can handle 8 amp continuously and upwards to 60 amps in surges. But the 8 amp is if heatsinked enough. If you insist on a 15 amp capability replace the triac with a 25-30 amp model instead. But will *still* need heatsinking. I triac usually drops upwards to 1 volt, so pushing 15 amps in a triac regardless of size will generate up to 15 watts, and that will generate a *lot* of head in a hurry.

Yeah or you could just make an idiot-proof low-voltage one, probably cheaper and easier. That’s the argument, low voltage is much easier to do safely.

A seam down the length— lower matching the carpet— would transform this interior. It would highlight the waterfall/separating element while lowering the visual height of the console.

I think we are past the early adopter phase. The general public will not want to use only 40 miles a day. We have charged our volt and ELR at 110, but I did add a 50 amp plug to our new house. I just purchased a JuiceBox EVSE. So I get faster charging now and I’m set for our next vehicle too.
