When should handholes be installed in a cable system?

Handholes should be installed in a cable system primarily to facilitate maintenance access. This is essential for various reasons, including the need for routine inspections, troubleshooting, and making repairs without having to excavate the entire cable run. By providing convenient access points, handholes enhance the overall reliability and safety of electrical installations by allowing technicians to address issues promptly and effectively.

The practice of installing handholes is not limited to specific environmental conditions, such as wet areas, nor is it bound by the voltage of the circuits. While voltage considerations may influence other aspects of installation, they do not dictate the necessity of handholes specifically. Furthermore, handholes are not only installed during initial construction; they can be added during upgrades or repairs to existing systems to improve access and maintenance efficiency. Therefore, the primary purpose of handholes is clearly centered on the ease of maintenance access.
