Now, a 20-amp circuit can only handle devices that draw up to 20 amps. We can see that, if we have a 240V circuit, we can run a 3,000 W heater on a 20-amp circuit. That’s because it draws less than 20 amps; 12.5 amps, to be exact.
我的结论是大致能够应付我的情况

                    12.5 AMP 是running的时候的安培吧,不是starting 安培。还有,你要加上所有其他主要电器的安培数啊
