That seems low. Like, my car has a single-phase 240V charger, and charges at three times that, continuous. My electric water heater draws 10 kW per phase (but it wants two phases.)
If you mean "single phase, 120V" then, yes, modern housing generally has 20A /12ga circuits, which are good for 2.4 kW, and older houses have 15A/14-16ga circuits good for 1.8 kW.
Regarding the HAAS TMs, remember that you have to pay another $1700 for rigid tapping, and another $3300 for "high speed machining," which really just means "don't just go to the next coordinate, then stop, then go to the next target, ..." Both of those features are already included for free in PathPilot / LCNC.
