Over the short distance of 25 feet no voltage drop calculations are needed to be made. A #10 copper conductor with an insulation rating of 60, 75 or 90 degrees C is rated at 30 amps respectively. 30 x 80% = 24 amps. If the load is under 24 amps then this size is the one to use. If the load current is greater than 24 amps then use a conductor one size larger. That would be a #8 which is rated at 45 amps x 80% for maximum wire loading = 36 amps.
For single phase 30 amps at 120 volts you would need a #8 copper wire with an insulation rating of 90 degrees C.
A #10 copper wire with an insulation factor of 60, 75 or 90 degrees C is rated at 30 amps.
I would recommend you use AWG #6 and a sub-panel for that long of a run.
This is a voltage drop question. To answer this question a voltage must be stated.

Depends on the wire size you are using. If the generator breaker is a 30 amp then install a 30 amp breaker.
#10 wire is used on a 30 amp service.
What size is the wire? AWG 10, 600V is rated for 30 amps. Any AWG less than 6 would also be ok for a 30 amp circuit....
A 30 amp breaker run 75 feet would require you use AWG #10 wire. But, an oven normally pulls more that 30 amps and I would not use #10 wire on a 30 amp breaker for an oven. Normally any newer oven is wired with AWG #6 gauge wire on a 50 amp circuit breaker so the breaker will not trip during heavy use of the oven. Some older ovens could use a #8 wire on a 40 amp breaker.
You never, ever mix wire sizes within a circuit. However you can wire a 30 amp circuit using AWG # 8/3 wire, although that is overkill and AWG #10 wire is what you would normally use on a 30 amp circuit.

It is unusual to have multiple outlets on a 30 Amp service. If you do this you need outlets rated at 30 amps and 10 AWG wire.
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker

AWG # 10 wire on 30 amp circuit.
A # 10 wire with a insulation factor of 75 or 90 degrees C are both rated at 30 amps.
This is a 30 amp 125 volt device. The black wire goes on the smallest pin, should be a brass coloured screw, the white on the next in size, should be a silver coloured screw and the ground wire on the pin with the inward hook on it, green coloured screw.
All depends on the size of the existing wiring. If you have a 30 amp breaker on AWG #14 wire then this is an unsafe condition that must be corrected. 15 amp requires that the wire be AWG #14. If the wire is #15 then you can and should install a 15 amp breaker. 30 amp breakers are used on AWG #10 wire.
Minimum size is 10 gauge with a 30 amp breaker. To be safe I would install an 8 gauge with a 40 amp breaker.
The ampacity or amp rating of all wire is rated by the size of the wire. NM (non-metallic sheathing) wire is no different. In household wiring 14 gauge wire must go on a 15 amp breaker/ 12 gauge goes on a 20 A and 10 gauge goes on a 30 Amp.
