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.
This question is best answered by knowing what equipment will be connected to the outlets, and what their expected current draw should be. It is also necessary to know what your voltage is.
You need to mention the voltage and the type of cable.
AWG #8 copper will work but I personally would use #6 for that long of a run.
You wil need to run AWG # 8 size wire.
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.
You need to mention the current or connected load to define the size of the wire
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.
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.
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.
To answer this question the voltage and load amperage is needed.
8 gauge will be sufficient with less than a half volt drop
AWG # 10 wire on 30 amp circuit.
This is a voltage drop question. To answer this question a voltage has to be stated. The higher the voltage to the circuit becomes the smaller the wire size needed. After a certain voltage point the wire size will remain constant and the voltage drop at the load will become smaller.
Wire size is calculated from the amount of current the load draws. More information is needed. Voltage and amperage will do fine.
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.
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.
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.
10 AWG in copper.
Normally wire is sized by the amperage of the load. In this case the wire size is calculated by knowing the length of the run to the load and the amperage of the device to be connected. By knowing the length, the wire size has to be increased to allow for voltage drop over the distance from the supply to the load.
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.
To calculate the wire size, a system voltage is needed.
