The minimum wire size for a 30 amp load is 10 gauge copper or 8 gauge aluminum. Assuming a 120VAC circuit and to maintain a maximum 3 percent voltage drop from load to panel, upsizing to 4AWG wiring would be the best selection for this circuit.

An accurate answer can not be given because the type of system has to be stated. Single phase or three phase and a voltage also has to be stated to be used in the calculation for sizing of the conductor.
A #8 copper conductor will limit the voltage drop to 3% or less when supplying 30 amps for 150 feet on a 120 volt system.

What is the type and size of cable gland or 2 core cable?
To answer this question the size of the cable or the amperage of the load is needed to calculate the correct wire size and connectors to fit the cable.
What wire do you use for 240 V 50 Hz?
You need to mention the current or connected load to define the size of the wire
How do you calculate mcb rating?
Circuit breakers are used to protect the conductor that is connected to it. The sizing of the conductor is based on the current of the load. As the connected load current is increased so must the wire size to accommodate that higher current. Therefore as the wire size increases so must the breaker size to accommodate the higher load current.
How to calculate the rating of the FUSE and Cable size. please tell the steps?
The calculations are worked backwards from the amps used by the load of the circuit. This will be used to select the correct size of the wire. Some stipulations are added depending of the ambient temperature, length from the supply or if the load is a motor. Fusing is then dependant on the wire size that is used.
What size wire do i need to feed a single phase V primary and a V secondary fed from a 150 amp circuit breaker?
Information is incomplete. You need to know the load in Watt or Kilowatt and the voltage on the secondary side to determine the load current, on which the size of the wire is designed.
What wire size needed for 120 volt 3000 watt load?
AWG # 10 wire on 30 amp circuit.
What size wire needed with a 100 amp load 250 feet away?
To determine the wire size needed for a 100 amp load 250 feet away, you will need to consider the voltage and allow for voltage drop. For a 100 amp load at 120V over 250 feet, you would need a wire size of at least 1/0 AWG. It's recommended to consult with a licensed electrician to ensure proper wire size for your specific situation.
What size wire is needed to operate a three quarter horsepower opener 250 ft from the breaker?
Wire size is calculated from the amount of current the load draws. More information is needed. Voltage and amperage will do fine.
What size wire is needed for a 180' run?
The wire size needed for a 180' run depends on the voltage, current, and type of installation. It is recommended to consult the National Electrical Code (NEC) and a professional electrician to determine the appropriate wire size to ensure safety and compliance with regulations.
What size wire do you need for a 208 volt 3 phase load that draws 10.5 amps?
The size of conductor needed will be a #14. It should be copper and have an insulation factor of 90 degrees C. The fact that it is a three phase load does not enter into the calculation of the wire size.
How many feet of wire to make a slinky?
The length of wire needed to make a slinky can vary depending on the size and number of coils. A standard slinky typically contains about 67 feet of wire.
What cable wire size for 1000 watts aircondition?
The only way to determine the cable wire size needed for a 1000 watt air conditioner is to find the load size. To get the load size you will need to use the formula Amps = Watts or Volts. With that being said, you will need a number 14 copper wire.
What is the type and size of cable gland or 2 core cable?
To answer this question the size of the cable or the amperage of the load is needed to calculate the correct wire size and connectors to fit the cable.
What wire size for world's simplest motor?
Wire size is based on the amperage of the load. Without knowing what the motors's full load amperage is, an answer can not be given.
What wire size is needed for 30amp load for 34 feet on 12 volts DC?
For a 30 amp load at 12 volts DC over a distance of 34 feet, a wire size of at least AWG 8 would be recommended to minimize voltage drop and ensure efficient power delivery. It is important to consult with local electrical codes and standards to ensure compliance with regulations.
What wire size is needed to 350 amp load for 100 feet?
#10 wire is good for 30amps; however it is wise and sometimes required to use an 80% load factor. If you need 30amps continuously you would want to use #8 wire, which is good for 40amps. #8 wire could safely run 32amps continuously, 40amps x 80% = 32amps.
What is the appropriate wire size for a 220 volt circuit with a 40 amp load?
For a 220 volt circuit with a 40 amp load, the appropriate wire size would be 8 AWG (American Wire Gauge) copper wire.
