When a wooden equipment frame is bonded to metal conduit, it acts as what type of conductor?

When a wooden equipment frame is bonded to metal conduit, it acts as a reference conductor. In this context, the bonding creates an electrical connection that establishes a common reference point for the electrical system. This is essential for grounding and ensuring safety, as it helps to stabilize the voltage levels throughout the system.

The term "reference conductor" specifically refers to the conductive pathway that is used to monitor and ensure that the grounding potential remains consistent. By bonding the wooden frame to the metal conduit, it reinforces the electrical safety measures in place, allowing any stray currents to be redirected safely to ground.

This type of conductor plays a crucial role in electrical systems as it helps in reducing the risk of electrical shock and equipment damage by ensuring that all components of the system remain at the same potential. Therefore, the bonding of the wooden frame to the metal conduit effectively serves as a reference that enhances the safety and reliability of the electrical installation.
