E-Feeder & Cable Calculator is a tool or software program used in the field of electrical engineering and construction to determine the appropriate size and specifications of electrical feeders and cables for various applications. This calculator helps professionals, such as electrical engineers, electricians, and construction project managers, in designing and installing electrical systems that meet safety standards and operational requirements.

The calculator typically takes into account several factors, including:

1. Load Requirements: It considers the electrical load that needs to be supplied by the feeder or cable, which is usually measured in kilowatts (kW) or amperes (A).
2. Voltage: The voltage level at which the electrical system operates is an important parameter. Common voltages include 120V, 240V, 480V, and higher.
3. Distance: The distance between the power source and the load is a critical factor in determining the size of the feeder or cable. Longer distances generally require larger conductors to minimize voltage drop.
4. Voltage Drop: Voltage drop is the reduction in voltage along the length of the conductor. Excessive voltage drop can lead to operational issues, so the calculator helps ensure that voltage drop is within acceptable limits.
5. Conductor Material: Different conductor materials, such as copper or aluminum, have different electrical properties, and the calculator takes this into account.
6. Ambient Temperature: The temperature of the environment where the cable or feeder will be installed can affect its performance. The calculator considers this when determining the cable or conductor size.
7. Allowable Current Carrying Capacity: The calculator also considers the maximum current-carrying capacity of the selected cable or feeder, taking into account safety standards and codes.

By inputting these parameters, the E-Feeder & Cable Calculator can provide recommendations for the appropriate size and type of cable or conductor to use in a specific electrical installation. This helps ensure that the electrical system is safe, efficient, and reliable.

These calculators are essential tools for designing and installing electrical systems, whether it’s for residential, commercial, or industrial applications, as they help prevent issues like overheating, voltage drop, and electrical failures.

Description
All directions and abbreviations are provided within the spreadsheet on the first page. The first page of the spreadsheet also contains a colour-coded Minimum Conduit Size Calculator. This will calculate the total area and the minimum conduit size. Various tables are provided in the second sheet of the spreadsheet.
