What size (watts) is this heating element?

[EequalsMC2]

Can anyone tell me what size (watts) this heating element is by size, description, and image? Aprox. length is 45", the shorter mid bend length is 39" with 1.5" radius at bends, O.D. is 5/16" (.312). My brother purchased then on e-bay a couple of years ago to build a vacuuming thermo former, that never got built. He only remembers them being 240 v. I now want to use them for an oven, if I can find out what I have.

Thanks,
Rick

Do an ohms(resistance) check on them. The formula is: current squared divided by resistance equals watts. As an example if it is a 240 volt element and the resistance is 20 ohms, then: 240 * 240 = 57,600 / 20 = 2880 watts. It's the only way of knowing for certain what the wattage is.

slighly different formula same results.

v devidedby ohms=amps x by volts = watts

240 volt devided by 20 ohms = 12 amps.
12 amps x 240 volts = 2880 watts

Thanks Ed, using the formula you provided I have 2742 watt elements. They will work out nice.

just a heads up... make sure you used *your* voltage in that formula... e.g. if your shop is actually 208V (like mine), the wattage will be lower. i think i used elements rated around 2600-2700W at 240V to get around 2000W on my 208V.
