Power for tablesaw in shop?
Initiated a new woodworking shop endeavor last week and have "anything
goes" on electrical from the contractor and wonder where the "typical" power source is for the TS whether 110V or 220V. Currently have 110V TS and it was plugged into a ceiling receptacle and was happy with that not having to step over a cord on the floor but inquiring minds wonder what other alternatives exist. Got the X10 for dust collection that was utilizing the same circuit and enjoyed it muchly. Small compressor can use either voltage but will probably convert to 220V for efficiency. Shop/garage will be 24X30 with 9' ceilings with half bath and drain board/sink adjacent and 3 windows with 18' garage door and person door. Anxiously awaiting completion! Anxiously awaiting responses also. |

It probably depends on how much you use it. I inherited my dads wood working equipment, and most of it is 220v but, he used it a good portion of every day, so it made sense to have it on 220v for the savings on electricity. I will say they are more powerful than before he made the motor switch, you just can't lug down the belt sander, and the table saw is like a hot knife through butter. I don't know if he upped the HP when he made the change, but they are sweet machines now. |

AFAIK, there is no energy savings to be had, running 220(240?) instead of
110/120. There may be less voltage drop when running 220, but no energy savings. DAGS for "120v 240v difference", and have fun. Clint "Eric in North TX" wrote in message s.com...

In 1999 I upgraded to a cabinet saw and use a 10-3 extension cord 30' long. I have never tripped over either. Until I have a larger shop with a stationary and permanent position for the saw, I will continue using the extension cord. |

I would make sure that the feed is a dedicated outlet. Then you can change
the voltage from 110 to 220 by just swapping out outlet an breaker. I would also go with 10 guage wire just in case you want to move up to a 5HP machine some day. The one outlet that I had to "add" in my (20x25) shop after constrution was the 110 under the saw outfeed table (my saw is in the middle of the room). I now have a power strip there so I don alway have to plug in on the perimeter of the room. -Steve wrote in message ...

Yes the amperage is cut in half because it's split between two circuts not because your drawing halve the wattage. The wattage stays the same and that is what your paying for. |

To continue what Rich said, around here we pay for electrical power by the
kilowatt-hour. Wattage = voltage * amps. So if your tablesaw draws 15 amps at 120v (15A * 120V = 1800W), it's the same as 7.5A @ 240V (7.5A * 240V = 1800W) in terms of actual power used, and therefore cost. BTW, when replying to (and quoting) someone else's post, it's poor practice to include the same quote identifier in front of your text. Makes it hard to pick out what you're trying to say. This is simply my opinion, unlike some people who will try to what an "Internet Standard" is (regarding top/bottom posting). Clint "JoeM" wrote in message ink.net...

The wattage used by the motor would stay the same, if the voltage to the
motor were the same, although even this is ignoring resistive losses within the motor. But the phrase "There may be less voltage drop when running 220, but no energy savings." does not make much sense: The voltage drop amounts to turning electricity into heat in the wiring, wiring in the building and in the power cord etc., and it unless you want to count that toward heating the building it is exactly enery lost, so if there is less of it at 220 then there is energy saved. There are lots of details if you want to go into them, such as the back-emf generated by the motor and how that falls off with load, but overall more of the electricity you are paying for will go into making sawdust at 220 than at 110. Going back to the first sentence, note that a different voltage drop makes for different voltage to the motor, so nothing here is simple. Bob Wilson "Rich" wrote in message . ..

Considering that unless you are making a living with it, the woodshop itself is a luxury item, I don't think a simple shower stall (and water heater, if slop sink OP mentioned was going to be cold water only), is much of a stretch. Few people bother to run water and drain to the shop, especially in a seperate building, but OP metioned a half-bath, so adding a shower to that becomes trivial. Unless a woodshop is a just a display room (like a yuppie restaurant-grade gourmet kitchen that seldom actually gets used), you do tend to get dirty working in there. aem sends.... |

It may not be a large difference, but higher voltage transmission lines will lose less energy to heat than lower voltage ones over distance. The same could be said for an AC motor winding. In theory, the power output of a motor running 15A at 120v is identical to the same rig running 7.5A at 240v, but in practice, this is not the case. As the load increases, efficiency declines and the motor will draw more energy from the mains in order to complete its task. the higher voltage motor will also suffer from this, but to a lesser degree. This is why you see large scale industrial motors running at higher voltages (and lower amperages), rather than using something like 120v/50A. I doubt that the savings in electrical cost will be enormous, but over time it will add up (or subtract up, down, whatever |

I missed the original posts, but from this post: 120 and 240v are both single-phase, Roger. He'd have to get a 3-phase motor and have the utility company put in 3-phase power (usually for beaucoup additional money IF they do 3-phase in his residential area.) -- Vidi, Vici, Veni --- http://diversify.com Comprehensive Website Development |
