A #6 RW 90 copper wire is rated at 65 amps. <><><> As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY

For a 240 volt 60 amp circuit, you should use 6 AWG copper wire or 4 AWG aluminum wire. Make sure to consult the local electrical code and consider factors such as distance and insulation type when selecting the wire size. It's always best to consult with a licensed electrician for proper installation.
For a 70 amp service at 240 volts, you would typically use a wire size of 4 AWG copper wire. This wire size is suitable for carrying 70 amps of current safely over a 240 volt circuit. Be sure to consult local electrical codes and regulations to ensure compliance with requirements in your area.
Yes, no problem at all going to a larger ampacity of wire. Larger size wire yes, smaller size wire no.
No. You will need a 14/3 with Ground.
A 3/0 copper conductor with an insulation rating of 90 degrees C is rated at 225 amps.
AWG # 10 wire on 30 amp circuit.
For a 70 amp service at 240 volts, you would typically use a wire size of 4 AWG copper wire. This wire size is suitable for carrying 70 amps of current safely over a 240 volt circuit. Be sure to consult local electrical codes and regulations to ensure compliance with requirements in your area.
The 240 volt receptacle has to have an amperage rating. It is this rating that governs the wire size and breaker size to feed the circuit. The new two pole breaker will be inserted in the 100 amp distribution if space is available and connected to the new wiring that terminates at the new receptacle.
A 1/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 30 amps for 500 feet on a 240 volt system.
In North America you would need two 15 amp breakers to obtain 240 volts. The wire for a 15 amp circuit would be #14 AWG. So to answer the question, yes a 240 volt receptacle can go on a 15 amp circuit.
10 gauge will work fine.

Yes, no problem at all going to a larger ampacity of wire. Larger size wire yes, smaller size wire no.
Use 8 gauge wire.
# 3 gauge
No. You will need a 14/3 with Ground.
20 amp
I think you mean 2 HP pump. I am assuming a 220 To 240 volt supply and that should equate to about a 12 amp current. All my pumps use only a 30 amp breaker and 10 AWG wire.
