What is the function of a mandrel in electrical work?

The function of a mandrel in electrical work primarily involves checking for obstructions. A mandrel is typically used in conjunction with conduit to determine if the path within the installed conduit is clear of any blockages that could impede the installation of electrical wiring. This process is crucial because obstructions can prevent wires from being properly pulled or installed within the conduit, potentially leading to unsafe electrical conditions or installation delays.

By using a mandrel, electricians ensure that the conduit is free from any debris or construction materials that could create issues during the wire installation process. This also helps maintain the integrity of the electrical system, ensuring smooth operation and safety.

While measuring voltage, connecting wires, or securing conduit are important tasks within electrical work, they do not pertain to the specific function of a mandrel. These tasks utilize different tools and techniques suited to their respective purposes.
