Power Consumption
At Idle  170 watts
2 channels @ 300W @ 8 ohms  1280 watts
2 channels @ 500W @ 4 ohms  2100 watts
Bridged @ 900W @ 8 ohms  2040 watts
btw i have no idea how much your typical 250 watt class a/b amp consumes
￼

The above numerical figures is the typical consumption of a 250 watt per channel @ 8 ohms Class A/B amplifier.
The above consumption next to the 4 and 8 ohms figures only comes into play when the amplifier is operating at maximum output (Clipping or just below clipping) at 4 and/or 8 ohms per channel. Wattage rating on amplifiers is rated at maximum output. Anything below maximum output the consumption will be less. It is similar to a hair dryer. The lower heater settings the lower the consumption, the higher the heater settings the higher the consumption.
The Idle Consumption of the amplifier is 170 watts, which is 1.4 amperes on a 120volt line source. So the amplifier consumes,
At Idle  170 watts
( 1.4 amperes on a 120volt line source)
2 channels @ 300W @ 8 ohms  1280 watts
( 10.6 amperes on a 120volt line source)
2 channels @ 500W @ 4 ohms  2100 watts
( 17.5 amperes on a 120volt line source)
Bridged @ 900W @ 8 ohms  2040 watts
( 17 amperes on a 120volt line source)
This amplifier will operate fine on a standard 15 amp, 120volt line source. Which is why, the manual recommends using nothing lower than a 15 amp, 120volt line source.
