The **Cable Tray Fill Calculator** helps you calculate the fill percentage for a cable tray, which is essential in electrical and construction planning to ensure safety and efficiency.

By entering values such as the fill percentage, cable area, or tray area, the calculator determines the missing variable, helping you assess cable management needs accurately.

**How to use the Calculator:**

- Enter any two of the following values:
**Fill Percentage (%):** The percentage of tray space occupied by cables.
**Cable Area (mm²):** The total cross-sectional area occupied by cables.
**Tray Area (mm²):** The total area of the tray.

- The calculator will compute the missing value based on the inputs.

**How To calculate**

**Example 1**

**Step** |
**Calculation** |

**Cable Area** |
500 mm² |

**Tray Area** |
2000 mm² |

**Fill Percentage (%)** |
(to be calculated) |

**Calculation** |
(500 / 2000) × 100 = **25%** |

In this example, if the cable area is 500 mm² and the tray area is 2000 mm², the fill percentage is calculated to be 25%.

**Example 2**

**Step** |
**Calculation** |

**Fill Percentage (%)** |
40% |

**Tray Area** |
2500 mm² |

**Cable Area** |
(to be calculated) |

**Calculation** |
(40 / 100) × 2500 = **1000 mm²** |

Here, with a fill percentage of 40% and a tray area of 2500 mm², the cable area is determined to be 1000 mm², allowing for an efficient layout of cables within the tray’s space.
