What size wire for 110 feet of 220 volt wire to a 30 amp planer?

The length of run and voltage are irrelevant, rating of the cable and where/how it is installed are what matter.
- 30A cable is 6mm2

A #3 AWG copper conductor will limit the voltage drop to 3% or less when supplying 30 amps for 200 feet on a 110 volt system.

For a 30 amp circuit over 110 feet at 220 volts, you would typically use a 10-gauge wire to ensure safe and efficient power delivery. This wire size is recommended to minimize voltage drop and ensure the circuit can handle the load without overheating. It's important to consult local electrical codes and regulations to ensure compliance.

∙ 14y agoAlthough # 10 gauge wire is rated to carry 30 amps, you should go one size larger, # 8 gauge because over 100 ft you will experience voltage drop. The larger conductor will compensate for that.

WELL ACTUALLY:If the distance isn't too great, you can use 10 AWG for 30 amps. Check the NEC or refer to the link below for a wire size calculator. Some Rationale:First of all the questions is poorly worded. The 220 volts is present in the electric panel and needs to be connected to a load by the proper gauge wire rated for the voltage, temperature and various other factors required by the specific application. For a typical residential application in the USA, such as an electric dryer or hot water heater 10 AWG wire is used. As to the length of the run, the longer the run the greater the resistance contributed by the size of the wire.For example, 10 AWG copper wire has a resistance of about 1/10 of an ohm per 100 feet. The maximum voltage drop should be less than 10%. So at 220 volts you don't want a drop caused by the wire to be more than 22 volts. Using Ohm's Law and assuming a maximum current or 30 amps and 100 ft. of 10 AWG wire with a resistance of .1 ohms we have:
30 amps x .1 ohms = voltage drop of 3 volts which is well under 22 volts. Even doubling the length to 200 ft you only get a 6 volt drop. So under most realistic conditions for a residential application 10 AWG is the answer.

Can you replace a 13 amp 125 volt appliance cord with a 15 amp 125 volt cord?
Yes, no problem at all going to a larger ampacity of wire. Larger size wire yes, smaller size wire no.
What size wire do I need for a 60 amp service either 750 feet or 500 feet away?
For a 60 amp service: At 750 feet away, you would need at least #4 copper or #2 aluminum wire to account for voltage drop. At 500 feet away, you could use #6 copper or #4 aluminum wire for the same purpose.
What wire size to use for 90 amp load at 480V at 75 feet?
Up to about 100 ft the size of the wire is determined by the max current and not the distance. A 90 amp supply needs #6 wire. <<>> A #2 copper conductor will limit the voltage drop to 3 percent or less when supplying 90 amps for 75 feet on a three phase 480 volt system.
What wire size needed for 120 volt 3000 watt load?
AWG # 10 wire on 30 amp circuit.
What size wire needed for 200 amp service 400 feet away direct buried single phase 240 volt 3 wire?
Assuming you are working with 240v, you need 4/0 copper conductors.
What is the required wire size for a 230 feet run 480 volt 100 amp?
Depends on length. The more length, the more resistance.
What size aluminum wire needed for 30 amp at 240 volt for 500 feet underground?
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.
What size wire in a 40 amp 12 volt circuit?
Use 8 gauge wire.
Can you replace a 13 amp 125 volt appliance cord with a 15 amp 125 volt cord?
Yes, no problem at all going to a larger ampacity of wire. Larger size wire yes, smaller size wire no.
What wire size 240 volt 21 amps 150 foot run?
A #10 copper conductor will limit the voltage drop to 3% or less when supplying 21 amps for 150 feet on a 240 volt system.
What size wire do I need for a 60 amp service either 750 feet or 500 feet away?
For a 60 amp service: At 750 feet away, you would need at least #4 copper or #2 aluminum wire to account for voltage drop. At 500 feet away, you could use #6 copper or #4 aluminum wire for the same purpose.
What size wire for an 80 amp 220 volt circuit?
# 3 gauge
What is the wire size for 208 volt?
As with any electrical installation, the wire size used depends on the expected maximum current the wire will carry. That cannot be determined by voltage alone.
What wire size is needed for 15 volt circuit?
The wire size depends on how much current it will conduct.
What wire size to use for 90 amp load at 480V at 75 feet?
Up to about 100 ft the size of the wire is determined by the max current and not the distance. A 90 amp supply needs #6 wire. <<>> A #2 copper conductor will limit the voltage drop to 3 percent or less when supplying 90 amps for 75 feet on a three phase 480 volt system.
What wire size needed for 120 volt 3000 watt load?
AWG # 10 wire on 30 amp circuit.
What size wire needed for 200 amp service 400 feet away direct buried single phase 240 volt 3 wire?
Assuming you are working with 240v, you need 4/0 copper conductors.
