Bitcoin Futures Deliver Wild Ride as Debut Brings Rally, Halts | 25 Amp Circuit Breaker

Online reviews are useful when you’re on the hunt for a trustworthy electrician. If the person with the lowest quote also has the worst ratings, it’s worth shelling out a bit more. If that cheaper electrician messes up, you’ll just need to call me (and my higher price) and pay more overall.

Yeah just what we need – another dopey ‘standard’. Putting stuff in right and using proper equipment is and has always been the solution.

A vaccum forming table design I looked at used ceramic rods made the same way with reflectors to evenly distribute the heat. I also own an electric kiln designed to heat and temper glass so a page can be taken from that design.

If I find a warm circuit breaker, I take a logical approach. First, is there a good reason for the circuit breaker to be warm? A 240-volt appliance like an air conditioner will definitely warm up a circuit breaker while it’s operating. No problem there. The image below shows a warm circuit AC circuit, but in this case, I do care about the temperature readings. This circuit is only about 8 degrees warmer than anything else in the image. This is not a significant difference, and it makes sense.

When I was doing rehab work on old Chicago apartments I would often find electric wires run through abandoned gas lighting pipes, ready made conduit going to where the old gas light fixtures were, not exactly code and very confusing, especially since there were “live” gas pipes mixed up in the walls and ceilings with the ones carrying Mr. 120!

Very interesting article. Being in the “treat it like radioactive anthrax” crowd, I rarely mess with mains level voltage, but I got a peek at what is required to do so. I read the paragraph about the “residual current circuit breaker” and thought it sounded very much like a GFCI (Ground Fault Circuit Interrupter). I clicked the link and sure enough, that was exactly what it was. I was surprised the article didn’t immediately describe it as such, but as mentioned in the Wiki that the link led to, only the US and Canada call it that.

Chassis floats with just 2. My folks lived in the middle east before my dad retired and I visited them in 2013. You could feel 50hz on the refrigerator door handle. Touching their aluminum iMac gave a nastier jolt. I remember my dad telling me, “yeah, don’t touch that” after trying to plug in a USB stick.

132KV is probably safer if you don’t test it with the back of your hand. It’s not like those little neon screwdrivers are expensive. You’d think in electrician training they’d have taught him about electrocution.

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.

Oh, and I have fixed about 15,000 of the old CRT TV’s so while my mistakes can’t ever be called good, they’re not without precedent.

Why do the US still use 110v mains and 20A room circuit breakers? Those currents are dangerous, not the volts.

2) If breathing and everything seems fine, there can still be some arrythmia that will manifest only hours later. It is a good idea to visit a doctor for EKG readings, or at the very least have someone monitor you for the next few hours and if you go unconscious, be present to give CPR & call ambulance.
