Assuming the service voltage is 240 volts. A 2/0 aluminum conductor, with an insulation factor of 90 degrees C, will limit the voltage drop to 2% or less when supplying 125 amps for 100 feet on a 240 volt system.

What size wire is needed for a 180' run?
To answer this question the voltage and load amperage is needed.
What wire size is needed for 30amp load for 34 feet on 12 volts DC?
8 gauge will be sufficient with less than a half volt drop
What pieces of information are needed before selecting a power supply?
The main piece of information needed is the load wattage or amperage that will be connected to the power supply. Once this is known the power supply of a greater size that the load should be chosen. Also with this information the size of the wires can be calculated from the power supply to the load. Too small a wire will create a voltage drop at the load end of the circuit. This will cause under performance of the load.
What gage wire do you use for 15 amps 200 feet?
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.
What wire size needed for 120 volt 3000 watt load?
AWG # 10 wire on 30 amp circuit.
What size wire is needed for a 180' run?
To answer this question the voltage and load amperage is needed.
What wire size is needed for 30amp load for 34 feet on 12 volts DC?
8 gauge will be sufficient with less than a half volt drop
What size diesel generator would you need if there was a power outage?
The size of the generator is based on the size of the load you want to supply. Size up the load in watts or amps along with what phase (single or three) and voltage that the load requires. These are needed to give a complete answer.
How many pulley needed to lift a load?
The number of pulleys needed to lift a load varies based on the size of the load. A very small load can be lifted with just one pulley while large loads may require many pulleys to adequately lift the load.

What size beam will span 18 feet?
That question cannot be answered without knowing the load on the beam.
What size open web steel joist be used to span 20 feet with dead load of 20psf and live load of 40 psf?
A DLH will work.
What size laminated timber beam is needed for a 23 foot clear span under a 15 foot roof in between load bearing walls -?
38 feet longIt is not possible to give a definite answer without more detail. The construction and type of roof will determine the load (weight) bearing on the beam, and factors such as wind load and earthquake load, and the way the roof bears on the beam (truss/point load/distributed load) will all affect the sizing.

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 size conduit is needed for wiring in Indian houses?
The size of conduit is based on the size of the wires in it. The size of the wires depends on the load connected in the house. Without these other two values an answer can not be given.
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.
