This new hybrid powertrain is more of a success than any that has gone before it at Toyota, thereby widening the options for buyers, and its warm performance will make it an interesting choice. However, with similar gains promised on the 1.8-litre drivetrain, and the incumbent money-saving gains it has, it remains to be seen which will be the pick of the range. 

Even with a large heat sink like that, shrink it to 50mmx100mm and the datasheet lists a max of 10A. With that aluminum plate, I’d be surprised if it could handle more than 5A for a length of time.

I have seen a 10cm hole blown right through the middle of circuit board. I have had many repair jobs that it’s been obvious that lightning has hit the overhead power lines, exploded parts, vaporised PCB traces. Non of these had any negative outcomes except having to repair the device or throwing it in the bin, generally the latter.

80%? When dealing with high current loads I top at 70% to allow for wobble of line voltage. For something like a Water heater I’d drop that to 50% ratings to make sure the surge doesn’t cause failure.

I am certainly not suggesting HVACR techs engage in performing work outside of their skills or licensures, but, in many cases, being able to identify the problem and making the repair are two different things.

They call those death sticks in the electrical trade. Those are just the first step in making sure it’s safe.

What’s the big deal? The heated rock for my herpetarium plugs directly into the wall. Nice cozy and warm. No shocks for me, no limp lizard either.

Uh, maybe i should not post using a foreign language a 01:00 AM… Correction: It should be broken –> It COULD be broken

This 225 percent of motor load/branch circuit allowance for breaker sizing is to allow for motor starting without nuisance trips while still providing circuit protection against short circuit conditions.

Flake, along with Sens. Chris Coons (D-DE) and Cory Booker (D-NJ), attempted for the second time to schedule a floor vote on the bill protecting Mueller on Wednesday, but it was blocked by Sen. Mike Lee, who argued that the legislation was unconstitutional (a longstanding conservative argument, explained by Vox’s Tara Golshan here). The bill would ensure that Mueller could only be fired by a Senate-confirmed DOJ official and enable the special counsel to review any firing.

Overall though, you’re just talking about increased RMS voltage allowing more current; the more current the more burn, heart arrhythmia and neuromuscular effects.

I understand it’s only about 20hz, which is why it gives you that interesting jiggly feeling instead of a good Wack like mains power at 50/60 Hz does. When I was still a young buck in my early 20’s I worked in a mid-sized company and one of my duties was to maintain our POTS lines; my boss who might have been a sadist would often have me remap the phone lines mid day while the lines were in use and insist that I was not to busy any lines out. I can only amagine my coworkers delight at the inventive array of profanity that would come out of the wire closet when the reception switchboard would light up during these sessions. Sti got my lines man’s handset stashed somewhere…lol
