Need to know the voltage of the circuit.
30 amps
To determine how many amps a battery can handle, this information should be on the battery itself. You can also get a battery tester to determine amperage.
You are probably thinking about 1/0 wire (1 ought wire). In copper it is rated at 175 amps and in aluminum 125 amps.
According to NEC, it's max rating in free air is 18 amps.
A wire is not like a bucket that holds amps but more like a pipe that lets the amperage flow through it. A # 14 wire is rated at 15 amps. Code only allows up to 80% for continuous use, 15 x .8 = 12 amps.

The amps that a four gauge wire will handle will depend with the thickness of the wire. If the wire is thin, the four gauge will handle 95 amps.
To determine how many amps a battery can handle, this information should be on the battery itself. You can also get a battery tester to determine amperage.
Just use Ohm's Law Voltage = Current x Resistance Amps = Voltage Divided By Resistance Amps = 120 / 260
Yes, the blower tends to draw too many amps. Too many amps in the circuit will overheat the wires and connecters and melt them.
It depends on how many amps it was designed for. A 12.5kV/600v 10kVA 3 phase transformer can handle ~.5 amps on the primary and ~10A on the secondary. A 600/120V 10kVA 3 phase transformer can handle ~10A on the primary and ~50 on the secondary.
Check the number of amps that your circuit can handle. You should not put devices with more than that many amps (total) on that circuit. Most houses are 15 amps and bathrooms 20 amps.

The blower motor is failing and drawing too many amps.
A 120V power supply connected to a 30 Ohm resistor will produce 120/30 or 4 amps of current.
A 1,000 watt inverter giving 110 volts is rated at 9 amps.
