How is conduit installed in concrete?

The installation of conduit in concrete requires that it be securely supported and placed according to specific spacing guidelines. This is crucial for several reasons. First, properly supporting the conduit ensures that it maintains its position and does not move during the pour of the concrete, which could lead to improper coverage or the potential for the conduit to be damaged. Additionally, adhering to specific spacing guidelines prevents issues related to structural integrity and accessibility for future maintenance or modifications.

Securely supporting the conduit also helps to maintain the necessary protection for the wiring within the conduit, ensuring it is not exposed to moisture or mechanical stresses. By following these guidelines, installers help to comply with electrical codes and standards that dictate safe practices for embedding conduits in concrete.

The other options do not reflect best practices in conduit installation; loosely laying the conduit may lead to instability, random embedding lacks planning and can interfere with structural aspects, and ignoring special considerations due to concrete mixing could compromise the durability and function of the installation.
