How can the capacity of distribution circuits be increased?

Increasing the capacity of distribution circuits is a fundamental aspect of enhancing the efficiency and reliability of electrical supply. Stringing a neutral wire and reconnecting transformers effectively enhances the overall distribution capacity by improving the balance of the load across the distribution system.

When a neutral wire is added to a circuit, it allows for better management of unbalanced loads. This is especially important in systems that have single-phase loads which can cause imbalances. By ensuring that the load is distributed more evenly across phases, the overall capacity of the distribution circuits can be maximized. Furthermore, reconnecting transformers allows for adjustments in the configuration that can lead to increased efficient power delivery and capacity.

This approach results in improved safety and stability in the distribution network, allowing for a higher throughput of electricity without overloading existing circuits. It's a practical method of addressing capacity issues without needing extensive infrastructure changes or augmentations.

The other options, while they may seem viable at first glance, do not provide the most effective methods for increasing the capacity of distribution circuits in the same way that adding a neutral wire does.
