How many amps would the circuit below draw? What if they were 2 kW, 3 kW and 4kW?
Anyone care to explain how you found your answer? Electricity stuff makes me feel totally inept. It always feels like I'm on the verge of understanding things and then I realize I don't know anything. (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif) I'm trying to wire up the heat lamps for the paint booth and I need to know what size wire we'll need and what size breakers to use.

its simple, divide your wattage by the voltage
watts/volts=amps electric code only allows you to load a cicuit to 80 % of the breaker, so after you get your amp rating mutiply it by 1.25. then your wire sizes are the following 12 is for 20 amp, 10 is for up to 30 amps, 8 is up to 40 or 50 depending on you local intrepritations (sp), 6 is good to 70 ( normally breakered at 60 ) you will have to break the heaters in to smaller circuits unless you want to use big wire. |
