Things Your Electrician Wishes You Knew | 25 Amp Circuit Breaker

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.

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

Andrew, here in the Land Up Over, Most residential power is single phase, A step down center tap transformer (pole pig) puts out 240 VAC from end to end and 120 VAC with respect to the Neutral (ground) center tap. Therefore the two phases are 180 degrees out of phase. These 3 wires are fed to the fuse box/breaker panel in the house. One hot goes down one side of the row of breakers and the other hot goes down the other side. Neutral is common, Ground is also in there, but whether it is connected to Neutral inside the Breaker Panel or outside may differ according to local regulations.

As it stands now, Republicans need Flake’s vote to pass any nominations out of the 11-10 Judiciary panel for floor consideration. Senate Majority Leader Mitch McConnell does have the ability to simply move these nominations himself, but so far he has not seemed interested in making this practice a habit.

Installing a ceiling fan might not sound complicated, but it’s nothing like putting together a barbecue yourself. You’re trying to figure out the motor while hoisting a 70-pound fan 12 feet above the floor. Call me up—I can finish the job faster and safer than you could.

24v 12a is not that much more at 288watts. I’m sure I’m missing something to do with electromagnetism which makes the secondary unnatractive?

Combining breakthrough translucent-mirror technology with Sony’s high-speed CMOS sensor prowess, the new Sony Alpha A33 and A55 break important new ground for consumer SLRs. Both deliver higher capture speeds than other consumer-class digital SLR, at 7 and 10 frames per second respectively, as well as true phase-detect live autofocus during video recording. Thrown in multi-shot technology (Handheld Twilight, Sweep Panorama, and Auto HDR modes) brought over from Sony’s digicam line, and the new cameras offer features not found in any other SLR, regardless of price point.

The third incident was also while I was working for the welding repair company. I had a previously perfectly working high-pot tester and needed to test the insulation on a transformer. The tester itself failed and shorted to the case – and I took 11kv AC to the fingers just by turning the power on. That stung a bit, but I got a new high-pot out of the deal, so a net positive.

All silly, make graphene in a blender combine it with acrylic paint, then paint it on. Making heated beds is anything but an art form. Or just use graphite.

Not at all. One lumberjack pushes while the other pulls, and they’re both pushing and pulling against the ground. It’s fits perfectly.

My situation is a good example. I just purchased a new house and unfortunately it does not have a garage. Until I get the garage built in the Spring with a NEMA 14-50 outlet, I’m going to rough it with L1 at 120V/15A.
