To allow a safe margin, what resistance value per jumper assembly is recommended in reference materials?

The recommended resistance value of 0.001 ohms per jumper assembly is significant because it strikes an appropriate balance between ensuring minimal energy loss and maintaining safety and system integrity in electrical systems. This low resistance value helps to reduce voltage drop and improve the efficiency of power delivery, which is critical in substation environments where reliability is paramount.

Having a resistance as low as 0.001 ohms also provides a safe margin to account for variations in temperature and material properties, which can affect resistance in real-world scenarios. This is particularly important in high-current applications where even minor resistances can lead to substantial heat generation, potentially causing damage or failure.

Moreover, industry standards typically aim for such value to mitigate risks associated with overloads or short circuits, ensuring the jumper assemblies can handle the necessary current without causing undue stress, which might lead to equipment malfunction or unsafe conditions. This value is in alignment with best practices in electrical design and safety protocols.
