What must be done during the ‘stubbing down’ process for ENT installation?

During the stubbing down process for Electrical Nonmetallic Tubing (ENT) installation, making a void before pouring concrete is essential. This step ensures that there is adequate space for the ENT, allowing it to be properly embedded within the concrete without damaging it or compromising its function. By creating a void, it facilitates the correct positioning and supports the integrity of the ENT installation, as the tubing needs to be secured in a way that it can effectively protect the electrical conductors inside.

This proactive approach prevents issues that could arise from installing ENT without considering how it will be contained in the concrete, such as potential damage during the curing process or improper alignment that could lead to future problems. Therefore, making a void is a critical component of best practices for ENT installation in concrete structures.
