Wire size is based on the amperage capacity of the service it is feeding. You tell me the service amps and I can tell you the wire size.
Yes, no problem at all going to a larger ampacity of wire. Larger size wire yes, smaller size wire no.
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.
To calculate the wire size you would have to find the amperage. I = W/E, 70000/240 = 291.67 amps. The wire size according to code has to be up sized to 125%. 291.67 x 125% = 364.6. 500MCM copper wire with an insulation factor of 75 and 90 degrees C is rated at 380 and 395 amps respectively. If parallel conductors were used the wire size for 75 degree wire would be 3/0 rated at 200 amps. Parallel conductors for 90 degree wire would be 2/0 rated at 185 amps.
A #1 copper wire with an insulation rating of 90 degrees C is rated at 140 amps.

A 3/0 aluminum conductor will limit the voltage drop to3% or less when supplying 125 amps for 175 feet on a 220 volt system. If the 125 amp load is a sub distribution panel that is not going to be fully loaded to 125 amps then using the exact connected load, which might be smaller than 125 amps will effect the wire sizing. The grounding conductor for that size distribution panel is #6 bare copper.
AWG # 1/0 copper would normally be used.

This is a voltage drop question. To give an answer the voltage must be stated.
depends on its use. If its for residential service its good for 125 amps In commercial and industrial installations it's a bit more complicated but you end up at the same 125 amps.
An L5-30P is a two pole three wire grounding 30 amp, 125 volt plug . The neutral wire is connected to the W terminal, the ground wire to the G terminal and the hot wire to the only terminal that is left. The small blade/slot is neutral (white), the larger blade/slot is hot (black) and the notched blade/slot is ground (green).

The Honda 125 is not bigger than a Honda 230 4 Stroke if the only difference is the size of the motor. The Honda 125 is actually a taller motorcycle than the Honda 230 4 Stroke when size is considered in inches from the ground to the seat.
