Also keep in mind that your alternator/voltage regulator output is not 12 VDC. It's anywhere from 12.8 to 14.6 VDC
At 12.8 VDC, 250 amps is 3200 watts, while at 14.6 VDC, that same 250 amps is 3650 watts.... Also, most alternator/voltage regulators are not rated at "maximum amps continuous" but are rated at "maximum amps for a period of time. You'll have to dig "deep into the specs" to get to the "continuous alternator/voltage regulator output... This statement is from one "reliable source": It is not uncommon for a 160 amp alternator to have a continuous duty cycle of less than 90 amps.
So, your 250 amp HD alternator may or more likely, may not have a "continuous output of 250 amps, and it "could be" that even though the alternator is rated at 250 amps, the voltage regulator may have a lower "maximum rating" or may have a different "continuous duty cycle rating".... It boils down to "what is the weakest link"....
