Ohio will let businesses pay their taxes with Bitcoin | 25 Amp Circuit Breaker

Your friend reminds me of a domestic main voltage electrician that would test with the back of his hand. He’s dead now.

But despite them being ‘commercial’, they’re still pretty hideous bits of cheap Chinese kit that I wouldn’t trust as far as I could throw them.

The best defense is to make sure you buy from reputable sources, not from some backyard hardware store or eBay.

Of course in many parts of the world that’s not possible like it is here in the US where better than 60% of homes have access to NG

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.

We drive about 30k miles/year, lots of long trips. After a trip, we usually pull in with 25-50 miles of range remaining. No problem – charging to the normal 80% is < 7 hours.

Let’s see, you’ve pooh-poohed my 12kV hit and [Scott_Tx]’s 90V one, so I guess 440V three-phase (was it the high leg, or one of the low legs?) is the sweet spot for you. Lucky for our edification that the boots did indeed save you. I knew someone who was quite thoroughly taken out by 220V in a basement while wearing (presumably damp) leather sandals.

If you’re worried about activists using media to promote fear and doubt about science and medicine,you’re in the right place. At Science 2.0, scientists are the journalists. with no political bias or editorial control. But we can’t do it alone so please make a difference.

Isn’t welding the core kind of a bad idea as it will short the laminated plates and make it heat a lot?

It is not enough to have the proper tools, you also have to use them in a safe way. The basic five rules go like this: 1. Disconnect from mains. 2. Secure against reconnection. 3. Verify that the system is really dead. 4. Perform earthing and short circuiting. 5. Provide protection from nearby live parts.

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

A coworker at JPL got bit by an ion pump supply. On-site health unit recognized abnormal EKG, sent him to ER. ER doctor diagnosed a congenital abnormality unrelated to the incident. But he ended up with a date with a nurse, so he considered it a worthwhile exercise.
