You may not have but other posters did and so it was a "reply all" more than just a reply to you only.


Well a Microwave vs Electric Kettle which are at the same voltage, then the discussion is strictly limited to which appliance is more efficient.. in that case I'd say the Microwave considering that both devices use around 10a @ 120v yet the Microwave will heat that water in 1/3 of the time of the kettle. That's what these "100% efficient" people don't get, if you look at all the losses down the line, it's most certainly not 100% efficient. Now in the case of my original question of Microwave vs Stove, I have no idea. While there are more losses in the household wiring used to power the Microwave compared to the Stove, the Stove doesn't have nearly the same efficiency in heating the water like the Microwave does since the Microwave heats just the food and the Stove heats everything.

Wrong.

Wow, and he's actually claimed to be in grad school somewhere, just think this moron may at some time be educating your children. I'm a little ashamed I fell for this train wreck again.

Grad school? He said he's taking online courses from a community college.

Wow this thread is still going??

grrl: yeah I recall fleabag mentioning somewhere about grad junior college school, pissed off at classmates, homework drama.

Lulz, you're confusing me with TridenT... I don't think I've ever complained about my classmates in College.. I can't even remember the last time I was so flustered with someone in school to bother even contemplating complaining about them.. Administration sure but students, no... If I was treated the way I'm treated in college in grade school (there's the e!), I wouldn't have been so resentful of those times. I'd say 99% of my hate in school was squarely placed on the authority figures or the administration. But, thanks for bringing up that unrelated tangent.

Dude we're in a fleabag thread. We always talk about warming up the truck at lake Tahoe in winter, about sidewall tire pressure and now about electric kettles too.

I've never felt like I belonged here. I do now...

:D

Here you go friend, have a seat and a glass of whiskey. First round is on me. I'd put on sunglasses just in case the kettle of Doom spontaneously combusts in a blaze of efficiency.

Probably a typo. Grade school.

I'm not talking about European vs North American circuits, I'm talking about 120v 60hz vs 240v 60hz. In the U.S, we have split phase where from the transformer on the pole, it has two out of phase wires coming into the house. Then, if you design your house properly, half the hot wires are one phase and the other half are another phase.

In the case of the oven, stove, and dryer, it takes BOTH "phases" of wire. The wires in most households on 15-20a breakers are around 12-14AWG, so it's better to have two 12awg wires than one 12awg. For my stove and oven, they're on 40a breakers, and it just so happens that they're at 240V. Because they're only DOUBLE the amperage of your regular household outlet and they're running twice the voltage, they can safely use the same sized wire as what goes into your outlets you see scattered around your house because there are more wires running into the circuit. If you run a 40a circuit and only put 10a of electricity through it, it's definitely going to have less resistive losses than a 20a circuit with 10a of electricity going through it. Can't think of a scenario like this? I can!

W. T. F. ??!!!

You are an absolute idiot. Your sidewall advice was bad enough. But, now you're suggesting that you can use the same size wire on a 40A 240V circuit??? You're going to burn your house down some day. That entire paragraph demonstrates that you have absolutely no idea what you are talking about. Pretty soon, computer vendors are going to have to put a warning label on their box - "Warning - keep bags out of reach of infants. Warning - do not listen to advice on the internet from someone called 'fleabag'."

As far as "designing a house right", it's pretty damn difficult to do anything but have half the 120V circuits (they're called circuits, not wires) on one phase and half on the other - unless you skip every other opening for a breaker in your breaker box. Making such a comment indicates you have no clue what you're talking about. Ideally, the loads should be anticipated & divided so that L1 and L2 have the same load. i.e. don't put the microwave circuit, the garbage disposal circuit, the counter top circuits, the bathroom circuits, and the shop circuits all on the same phase, while relegating each bedroom, dining room, kitchen lighting, etc. to the opposite phase.

And again, the resistive losses inside a house are completely negligible. Resistive losses = heat. That's why we have electrical codes that dictate the size of wires used. Lastly, it's capital A! 20A, not 20a.

General Electric... an overpriced heap of..

The GE Microwave I installed during my kitchen remodel is awesome - best microwave I've ever owned. Except the listed dimensions are something and 3/16". Reality: something and 3/8". Really sucked that I tiled the backsplash while waiting for the microwave to be delivered. Then, I discovered that the 1/8" gap that I left, figuring to fill it with grout wasn't enough. What a dusty mess it made cutting those porcelain tiles with a dry blade indoors.

Apparently you can't even keep your lies straight for 5 days.

Do I qualify?

So I recently went back to grad school and we have those dread group projects . I didn't really know anybody because I just started in the spring semester, so I just joined up a group that was looking for members. I figured it was easier than starting my own group and there weren't very many project choices left anyway...
