Re: Tankless revisited... said by whizkid3:The only possible exception is perhaps some GE panels, where it would work and would be listed for this use and perfectly acceptable.
I think it was a Cutler Hammer panel. This was the breaker; »www.homedepot.com/webapp/wcs/sto···00176080
The breaker appears to be able to be tied, so I'm assuming it's correct, it just struck me as wrong the first time I saw it. |

kudos:8 | It won't provide 240V in a residential 120/240V panel. Ever.
Its also described incorrectly as a double-pole breaker. Its a single-pole duplex breaker. |

I think those are what I have in the bottom of my GE panel... |

QFT. AKA tandem breaker.

Well they did, using the miracle I mentioned earlier. Hot to one half, neutral to the other, and bare ground for equipment neutral. Went to a window shaker A/C. |

Thanks. If that's what sk1939  was trying to discuss, he was way, way off in is terminology. The photo above is of single-pole breaker; which will not provide 240V, regardless of whether its a CTL panel or not; and whether or not someone improperly modifies the circuit breaker or bus stab.
Onto your point, I think its pretty well understood here, that if one wants to use duplex breakers in a panel; the panel has to be listed and designed for their use; and they can only be used in positions designed for their use. The NEC requires panelboards to be constructed to prevent improper use. |

[modifying a non-CTL duplex breaker] Hot to one half, neutral to the other, and bare ground for equipment neutral. Went to a window shaker A/C. No, they did not. Using only one hot wire in a 120/240V panel does not provide 240V, ever. Modifying a CTL duplex breaker to fit in a non-CTL slot and somehow getting 240V out of it would indeed be a miracle. Unfortunately, its impossible. |

I am, since I couldn't remember the terminology for some reason.
Don't say it can't be done, because idiots are so ingenious.
Yes they did, because using a [CTL] tandem breaker, they used 20A (Black) 20A (White) and Neutral (Bare Ground). Mind you, this was a modern Cutler Hammer BR panel, not a classic split bus. |

kudos:8 | Now you're posting photos of two-pole breakers that take up two single-pole slots. sk1939 you're a long way off from the discussion you brought up, and keep on twisting your points into different ones until you find one that works. So lets summarize and wrap this up with some properly stated facts.
- one can't get 240V from a single-pole breaker.
- two-pole breakers don't fit into a single pole slot no matter how hard one tries unless they break it in half, because a 2-pole breaker is twice as wide (or more) than a single-pole breaker.
- a 20A breaker is not a 40A breaker. This has nothing to do with the voltage needed. The current rating of a breaker is what it will provide regardless of the voltage.
- 2-pole breakers in a single-phase panel automatically balance the load.
- Breakers are not permitted in panel locations that are not listed for their use, regardless of the situation.
- Duplex and tandem breakers are single-pole. Quadriplex (dual-pole) breakers are also made. They take up two slots in a panelboard and will provide 240V. |

| Perhaps, not really trying to twist points however. The point I was trying to make it that yes, CTL breakers can fit into non-CTL panels. The double pole breaker was just another example of modification rather than what I was talking about.
Unless it's a tandem.
Yes, but I meant tandem rather than double pole.
Agreed with the rest of the points.
Sorry for straying so far off topic. |

in the United States He qualified it earlier ... from a "120/240" source.
In addition, in the US, grounded B phase could give you 240 from a single-pole breaker (between either A or C and ground) although I'd be surprised to hear of any such installation in a typical residence.
But getting back on topic, I'd like to thank my fellow posters for the BTU calculations on the magnetron heater. What's next in the OTC sales pitch lottery ... a self-sustaining heater powered by Russian nuclear waste?

 A nuke tankless HWH..
Yes, after extensive calculations pumped by that warm and fuzzy feeling driven with currency emotions I think we can put the magnetron heater safely in the pump and dump category...

in the United States It has nothing to do with the United States. I clearly explained earlier that you can't get 240V from a single breaker 120/240V single-phase system. This applies anywhere in the world. |
