Hi everyone, I'm trying to find the volt & amp to my 60w centrifugal fan & I have googled for the specs online & emailed the store where I bought it, yeah I ain't get sh** so..my calculations here is 15 volts x 4 milliamps = 60w & 12 volts x 5 Milliamps = 60w Can I have it both ways or nah..
Are you sure you mean milliamps? I assume you mean amps instead. 15 volts x 4 milliamps = 0.06w 12 volts x 5 milliamps = 0.06w Is there an electrical sticker of any kind on it?
Also remove the cover and look for labels. If still nothing just replace it imo. What's it currently running on, 12/5 or 15/4?
Yes I was sure & now I know I have been corrected, Thanks, its 15v X 4A = 60w & 12v X 5A = 60w. Power : 60w Voltage : 240v Speed : 2550rpm Current : 26A Frequency : 50Hz Capacity : 2micromolF/450v I'm trying to figure out the breaker for this thing in amps if it makes any sense
How to Convert Amps to Watts It is also possible to convert amps to watts using the Watt’s Law formula. The formula to convert watts to amps can be converted using algebra to also read: watts = amps × volts Thus, to find the power, or wattage, simply multiply the current in amps by the voltage. For example, find the wattage of 8 amps at 120 volts power = current × voltage power = 8A × 120V power = 960W 1 kilowatt is equal to 1,000 watts, thus it is possible to use the formulas above to also convert kW to amps, but watts need to be converted to kW first. Use our kW to amps calculator to solve for kilowatts. Equivalent Watts and Amps at 120V AC wattage to amperage conversions at 120 volts.

Thanks for that, but what if I don't know the volts & Amps to the product but only the wattage. There may be no name of the model or specs to it
The voltage should be known. If it’s a residential outlet it’s 120v. So you can divide watts by voltage. For example. A 1000 watt light at 120 volts would be 8.4 amps. Sent from my iPhone using Grasscity Forum
Like @Dblee, @Headhunterpipes, @Reo, @DaPhats, has said, take 60W and divide by whatever the Voltage is being supplied to the outlet that the fan is plugged into, then you'll calculate amps flowing into the fan assuming PF is 1. A fan uses a motor which creates an inductive load. These inductive loads can have poor power factors which means that they could potentially draw more current than what you'd expect if not including PF into your calculation. PF only effects AC powered loads. (VoltsAC * AmpsAC) * PF = Watts Watts = PF * (VoltsAC * AmpsAC) Assuming a PF of 1 on a 120VAC outlet... 60W = PF * (120VAC * Xamps) 60W = 1 * (120X) 60W = 120X X = 0.5A Assuming a PF of 1 on a 240VA outlet... 60W = PF * (240VAC * Xamps) 60W = 1 * (240X) 60W = 240X X = 0.25A Assuming a PF of 0.8 on a 120VA outlet... 60W = PF * (120VAC * Xamps) 60W = 0.8 * (120X) 60W = 96X X = 0.625A Assuming a PF of 0.8 on a 240VA outlet... 60W = PF * (240VAC * Xamps) 60W = 0.8 * (240X) 60W = 192X X = 0.3125A At a lower PF the amount of current the fan will draw will be greater than if it had a high PF of 1 (highest). Devices under 75W aren't regulated to have extra circuitry to have their power factor corrected, so Im assuming the fan will draw a bit more current than what you'd traditionally expect due to my assumption the PF is under 1. A $10 "kill-a-watt" meter will give you a PF reading.
