Hi All; I want to buy one of those lunchbox size 240 volt construction heaters for my shop. The one I’m looking at is 4800 watts. I want to know what it draws in amps. I did the coversion, but I think I got it wrong.
Any help would be appreciated.
Thanks. Shawn

It would draw 20 amps and would need #10 wire, 30 amp breaker and 30 amp dryer receptacle
Thanks for the info. I'm already wired for that, except for the dryer recept.
Cheers. Shawn
One more try!
Thanks VAVince; The calculator works great!
Cheers. Shawn
Here is another way....
P = I x E
Where P = power (watts) I = current (amps) E = voltage (volts)
or P/E = I
No need for a dryer receptacle.The heater is 240 volt. A dryer is 120/240 and needs a neutral connection.While you can use a dryer receptacle and plug, if you have also run the neutral. But for a basic 240 circuit use a nema 6-30.http://www.leviton.com/sections/techsupp/nema.htm
So right , Bill. Should have walked to my shop about 18' from computer as I bought one at a yard sale 4-5 years ago and there it still sits not hooked up with a 6-30 plug!!
This is my first time attaching a file on BT. Hope it works!
The calculator works but does not show the ohms law.I will try again.
