How much does electricity used by running a treadmill for an hour for a month cost?
It depends on the rating of the motor. There is usually a nameplate on the frame that provides these details. Mine is stamped 120V and 15 amps. That translates into (120)(15) = 1800 watts or 1.8 kilowatts (KW). If you run this motor for 1 hour, you will consume 1.8 kilowatt hours (KWh). If you look at your utility bill it will tell you the cost of 1 KWh.Example: If 1 KWh costs 12 cents and you operate my treadmill for 1 hour the total cost is (.12)(1.8) = .216 or 22 cents.If your motor is rated in horsepower instead of watts you can convert that number to watts with this formula. 1 hp = 745.6998 W and divide the watts by 1000 to convert to kilowatts.Example: 1.5 HP = (1.5)(745.6998) = 1,118.5 watts or 1.12 KW
What is the safest way to ground electrical equipment in a basement when a grounding rod can't be placed under the floor?
electrical devices have multiple ways to ground usually through the wiring itself. However if the extra ground wire is not there like in some older wiring cases you can run a new ground wire.Either having a new line with a ground pulled into your device sometimes through tubing or with romex containing a ground. Depending on the device you may need a heavy bare ground wire. You can buy these items at Home Depot or local electrical outlet. This can all be done with a fish tape and a little thought process. Example.Not knowing exactly your situation the simplest answer is to use your fish tape and pull new wire with suitable ground to your electrical panel and terminate your ground there.Electrical panels use a common bar that has a direct ground wire to your ground stake.
Electricity out in two rooms.?
I have electricity out in two rooms in my house that are on the same circuit. I don't know much about this sort of thing so any suggestions would be appreciated.
What happens if i have 240vac witing powering a subpanel in the shed and hook 120vac wires from the subpanel to outlets?
Trying to get to the bottom of a DIY project. I have 3 wires comingfrom the house basement control panel to the shed outside. A white black and ground. If its 240vac does that mean both white and black wires are hot? If thats so where is the neutral to complete the circuit? Secondly, assuming the white and black wire are not both hot wires, and they are a neutral and a hot wire, what'd happen if the subpanel that is powered by the lines comingfrom the house, is wired with 12-2 romex from the subpanel to a few outlets(120vac) in the shed ? How can this project work? 240vac comingfrom the house and 120 in the shed? Also does the subpanel need a ground rod if theres already a green ground coming from the house?
Can we use solar panels without a battery?
Hello.Yes! You can!Solar panel and battery are two independent components of solar PV system.Battery is only required if you want to have energy storage.When solar panels are exposed to sunlight they generate electrical energy (DC). This generated electricity can be readily used or can be pumped into main utility grid(after inversion) (this doesn't require battery).In simple words, if you want to utilize generated electricity from solar after sun sets, then you need to store that electrical energy into battery.Above figure shows simple solar power system(with battery)Following links will help you to calculate battery sizing: Battery Sizing Calculator Sizing the battery bank for your off-grid solar power system SO you require battery only if you want to have energy storage.And you know that high capacity(MW rating) solar power plants don't have any battery systems. Because they directly pump the generated electricity into utility grid after inversion.I hope your doubt is cleared! For more information or any query you can comment.Thanks a lot!
Are infrared heaters energy efficient?
It depends on the situation. The key detail to note is the difference between efficiency and effectiveness.Infrared heaters are about 85% efficient at emitting radiant heat, while the rest of the heat is conducted through the frame. If the heat conducted through the frame contributes to whatever you are trying to heat then the infrared heater can be considered as 100% efficient at converting electricity into usable heat. If 100% sounds high consider this: The use of a heat pump for heating can have a coefficient of performance of 2-4. COP is not the same as efficiency because the heat pump moves heat rather than generating it, but the result of its use is that it is up to 4 times more efficient at using the energy than that infrared heater. There's also's effectiveness to consider. I once surveyed a railroad car machine shop building that operated year round. In the winter they would periodically open gigantic doors to switch the cars out and bring in a fresh 40 ton ice cube (rail car) to work on it. In this situation using infrared heaters is highly effective because it heats objects directly. Using traditional convection heaters to heat the air would be a bad choice here because all the hot air would escape every time they switched cars. That said, radiant heaters are directional so it feels like trying to warm up by a bonfire on a cold night. One side of your body gets warm and the other freezes. The last thing to consider is what is effective vs what is cheap. Natural gas is so cheap that it often makes sense to use a forced air convection heater (~80% efficient) instead of an electric powered infrared heater.
