What calculation did you do to convert 7000 Watts to 510 Amps? P= V * A 510 Amps at 24 Volts = 12,000 Watts?? For what it is worth, the name plate on the motor on my older Super Maramu (they might not all be the same) is 6.3kW To get a good number, for current draw you can't assume 24 Volts. When you are drawing that much power, the voltage will drop, a lot. For really high power draws like this, it is not unreasonable to assume as low as 18 Volts. 6,300 Watts/18 Volts = 350 Amps If we do go with a 7000 watt rating, that's still "only" 388 amps. A perfectly reasonable number to protect with a 500 Amp fuse.
