It's going to take a whopper of a wire to run a 20 amps 650 feet. I'd feel more comfortable if a journeyman electrician would come by to access my answer. But, my calculations show it would take 4 AWG wire to do it. If you want you could run two 7 AWG wires in parallel.

∙ 8y agoThis is a voltage drop question. To answer this question you need to state a voltage. If this is not a commercial or industrial three phase question, the voltage will be considered at 120 and 240 volts.
A #4 copper conductor or a #2 aluminium will limit the voltage drop to 3% or less when supplying 100 amps for 300 feet on a 240 volt system.
A #1 copper conductor or a 2/0 aluminium will limit the voltage drop to 3% or less when supplying 20 amps for 650 feet on a 120 volt system.

What size wire for 100 feet 20 amp circuit to run pond fountain?
12 gauge underground wire or if you think you will ever add any devices to this circuit use 10 gauge.
Is it safe to go from 12-3 wire to a 14-2 wire in the middle of a switch leg?
No. The wire size is dependent on the circuit protection. If the circuit uses a 20 amp breaker you need to run 12 AWG wire on all devices connected to that circuit.
What size wire do you need to run 100 ft 75 amp 230 volt?
Depends on the size of the circuit which you did not list.
What size amp circuit breaker should be used for a geyser?
Depends on how many amps it pulls and the size of the wire in the circuit.
Is number 10 wire good for a 20 amp circuit that is 250 feet?
Assuming you are working with 120v, you need #4 AWG copper conductors.
What size wire do you need for 220 feet?
Cannot answer this question. Will need to know the voltage and amperage of the circuit. Also need to know the application i.e. is it a lighting circuit or a motor circuit?
What Size wire do you need to run a 30 amp circuit 50 feet?
AWG 10 guage.
What size wire do you need for 42 amp circuit?
8 AWG copper.
What size wire and breaker do you need for a 200 amp continuous duty circuit?
AWG 2/0 copper wire.
What gauge wire do you need to run a 30 amp circuit 100 feet?
8 ga

What size wire do you need to run to an air conditioner that has a maximum breaker size of 40 amps and a minimum circuit size of 25.3 amps?
Number 10 thnn copper wire.
Should you Run a 20amp circuit 150 feet with?
If this question is asking about voltage drop, to size a wire, a voltage is needed.
How do you wire a high watt light to a battery?
Need more information. Wattage of bulb, voltage of bulb, voltage of battery and wire size of the circuit.
What effect would thinner wire have in a circuit?
The smaller the wire size used in a circuit limits the amount of current that is allow to be flow through that circuit.
