For a branch circuit with a load of 50A operating at 100', what would be the recommended load center length to consider?

In determining the recommended load center length for a branch circuit, it's essential to consider not just the distance from the load but also to account for various factors such as voltage drop, the potential length of wire run, and where the load center is located in relation to the load.

For a branch circuit with a 50A load operating at a distance of 100 feet, you need to consider that the actual length of wire required is longer than the straight-line distance to account for the necessary connections and terminations. This is where the load center length comes into play. Usually, a little extra length beyond the distance to the load is recommended to accommodate these factors.

In this case, a length of 93 feet would be adequate to ensure that the entire length of wiring, including any necessary bends and connections, can be accommodated without risk of exceeding acceptable voltage drop limits, which could be detrimental to the operation of the circuit. This makes the option of 93 feet a prudent choice, ensuring that the installation adheres to standard practices for safety and efficiency in electrical design.
