When installing ENT through bored holes in wood members, the holes must maintain a specific edge distance. What is that distance?

Maintaining a specific edge distance when installing Electrical Nonmetallic Tubing (ENT) through bored holes in wood members is essential for ensuring structural integrity and proper functioning of the installation. The correct edge distance of 1 1/4 inches serves several purposes: it helps prevent damage to the wood member's structural capacity, reduces the risk of splintering, and ensures that the tubing is securely positioned, minimizing the potential for movement or stress on the tubing.

An edge distance of 1 1/4 inches ensures that there is ample space between the hole containing the ENT and the edge of the wood member, adhering to best practices in electrical installation and code requirements. Proper adherence to this standard also contributes to the safety and longevity of the installation, thereby preventing potential hazards such as electrical shorts or damage to the wood structure.
