When adding a secondary circuit, what adjustment is required for the sizing of mains and circuits?

When adding a secondary circuit, it is important to understand that the existing system can often accommodate the additional load without necessitating adjustments to the sizing of the mains and circuits. In many cases, especially in well-designed systems, the current mains and circuits have sufficient capacity to handle the extra demands imposed by a secondary circuit.

For example, if the mains and circuits were designed with a margin for future expansion or increased load, operators can integrate a secondary circuit seamlessly. However, it is crucial to assess factors such as flow rate, pressure drop, and overall system efficiency to ensure that the existing setup will indeed manage the added circuit effectively.

In scenarios where existing mains are already nearing their capacity, re-evaluating the capacity of the mains and circuits may become necessary, but typically, the fundamental design principle allows for simple integration of additional circuits without significant alterations to the infrastructure.
