David, if that cable is NM (Romex) then it actually cannot carry 50 amps . What is 18 gauge wire used for This is a good goal to shoot for when sizing the conductors for an underground cable. The following are the maximum lengths of cable you can use while still maintaining a 3 percent voltage drop for the given wire size (AWG) and circuit voltage. As an example, for a 120-volt circuit, you can run up to 50 feet of 14 AWG cable without exceeding 3. You can usually fit 10 AWG wire under the screw; 8 AWG usually won't fit. Whereas 12 AWG is rated for 20 amps and 8 AWG is rated for 40 amps under normal conditions, a circuit wired with 12 AWG could drop below 110 volts at the end of a several hundred foot run when loaded to capacity A 240 volt, 30 amp circuit would require 4/3 AWG wire. 500 Feet - a 120-volt, 20 amp circuit would require 1/0 AWG wire.

If we repeat the exercise and ask ourselves how many Amps equals 1000 Watts, we get: I = 1000 Watts/120 Volt = 8.33 Amps. We see that a 1000 W device draws twice as many Amps as a 500 W device. For 220V, we get this watts to amps calculation: I = 1000 Watts/220 Volt = 4.55 Amps. In short, 1000W draws 8.33 amps at 120V, and 4.55 amps at 220V
