The Faber cable calculator app – the free professional tool.

The Faber cable calculator is an indispensable tool for the day-to-day work of installers and planners. Be it at the building site or in the office: Calculate cable diameters quickly, easily and precisely. All you need is an active internet connection.

What can the Faber cable calculator app do?

The Faber cable calculator app serves to perform simple calculations for dimensioning cable diameters.

Upon entry of the:

- Electric power or rating,
- Cos phi,
- Length/distance

the diameter required for copper and aluminium cables is calculated for the most commonly used cable designs and in consideration of the installation types – in ground (direct, conduit/duct), in buildings (in/on walls, in air, cable conductors, cable trays) – and then directly output as a list with the Faber article numbers. The calculated results are directly linked with the Faber product pages and can be sent to any desired e-mail address.

How does the app work?

After starting the program, enter the basic settings first:
• Nominal voltage
• Maximum permitted voltage drop
(further guidelines and standards may need to be observed here!)
• Cos phi (power factor)
• Power (in kW) or current (in A) to be conducted
• Cable length

Now you can enter the installation type:

• Direct in ground
• In ground (in conduit / in duct, installation type D)
• Building (in / on wall, installation types A1 to C)
• Building (in air, installation types E to G)

If required, you can also enter a different load factor (0.7 or 1). Specific installation types also provide you with an opportunity to select the number of circuits, the ambiant temperature or the installation gap.

The "Calculate" button serves to list every product from the Faber range that meets the entered requirements. The attendant product page is accessible with a single click. The list of matches can be sent to any desired e-mail address.

Please note: If the entered conditions fail to yield a plausible result (e.g. excessive power or cable length), an error message will be displayed. In this case, halve the power, for example, in order to simply connect two of the calculated cables in parallel.
