Calculating needed cable diameter

In summary, needed cable diameter is the size of a cable required for safe and effective transmission of electricity. It is calculated by considering factors such as current, distance, and cable type. It is important to calculate the needed diameter to prevent hazards. Tools and resources such as online calculators and textbooks are available to assist with this. The needed diameter can vary for different types of cables, taking into account their specific properties.

Hey!

How can I calculate what should be the cable diameter by the amper / watt?


Best Regards,
Liad.

By Amp. And it is probably easiest to just use the tables in the NEC or other code book (if you aren't American).

1. What is meant by "needed cable diameter"?

Needed cable diameter refers to the thickness or size of a cable that is required to safely and effectively transmit electricity from one point to another.

2. How is the needed cable diameter calculated?

The needed cable diameter is calculated by considering factors such as the amount of current being transmitted, the distance the cable needs to cover, and the type of cable being used. These factors are used in mathematical equations to determine the appropriate diameter for the cable.

3. Why is it important to calculate the needed cable diameter?

Calculating the needed cable diameter is important because using a cable with an inadequate diameter can lead to overheating, voltage drops, and potential safety hazards. It is crucial to choose an appropriate diameter to ensure efficient and safe transmission of electricity.

4. Are there any tools or resources available to help with calculating needed cable diameter?

Yes, there are various online calculators and software programs available that can assist with calculating the needed cable diameter. Additionally, electrical engineering textbooks and resources can provide equations and formulas for manual calculation.

5. Can the needed cable diameter change for different types of cables?

Yes, the needed cable diameter can vary depending on the type of cable being used. For example, a copper cable may require a different diameter than an aluminum cable to transmit the same amount of current. It is important to consider the specific properties of the cable when calculating the needed diameter.
