Amp draw is always combined. 220V is uncertain if it is three phase or not, because there are both one phase and three phase applications of the 220V motor. In any case, the answer is always "combined".
To answer this question the amperage draw of the motor must be given. This amperage is then divided into the amp hour capacity of the battery to find the endurance time of the motor.
If you put a 85 amp breaker in there it will overheat from the starting and stopping of the motor. The extra size of the breaker insures that the furnace will run without interruption and without overheating the breaker. And electric motor can draw three times the amperage rated on start up momentarily. This is why there is need of extra amperage ratings.
Assuming this is not an office of a place where lots of the outlets will be used to power items that draw lots of current on a 15 amp circuit wired with 14/2 wire I would limit it to no more than 10 outlets and lights combined. On a 20 amp circuit wired with 12/2 wire I would limit it to a 14 outlets and lights combined. There is no limit in the code. You just use common sense based on what is going to be used on this circuit.

You will need AWG #3 if it is a short run.
The maximum current capacity of a 220V 20 amp outlet is 20 amps.
Either. Motor size or your available power local to the pump installation are the determining factors. If you have to use a large motor, 220v requires less amp draw on the circuit and allows a smaller wire than a large motor running 110v. If 110v is already there and you only need a small motor, run 110v.
The recommended wire size for a 220v 20 amp circuit is typically 12-gauge wire.
The recommended wire size for a 220v 30 amp circuit is typically 10 gauge wire.
The appropriate wire size for a 20 amp 220v circuit is typically 12-gauge wire.
The appropriate wire size for a 220v 30 amp circuit is typically 10 gauge wire.
The recommended wire size for a 60 amp 220v circuit is typically 6-gauge wire.
For a 220V 30 amp circuit, a 10-gauge wire should be used to ensure safe and efficient electrical conductivity.
For a 30 amp 220v circuit, a 10-gauge wire should be used to ensure safety and proper functioning of the circuit.
For a 20 amp 220v circuit, a 12-gauge wire should be used to ensure safety and proper functioning of the circuit.
For a 220V 20 amp circuit, the appropriate wire size is typically 10 AWG (American Wire Gauge) for copper conductors.
