What is the purpose of a handhole in electrical installations?

The purpose of a handhole in electrical installations is primarily to serve as a smaller access point for cable maintenance. Handholes are typically used in underground electrical systems to allow technicians to access and manage cables without the need for extensive excavation. This access facilitates maintenance, repairs, and inspections, making it easier to ensure that the electrical system operates correctly and efficiently.

A handhole helps reduce the time and effort required to access electrical components, helping to keep the system safe and functional. Unlike larger access points such as manholes, handholes are designed for more limited access while still providing sufficient space for routine maintenance tasks, such as inspecting connections or handling cable splices.

In contrast, the other options refer to functions that are not aligned with the primary use of a handhole. A handhole is not specifically a connection point for devices, nor is it intended to serve as a fuse box or a location for circuit breakers. Instead, it functions primarily as a point for safe access to buried cables, focusing on maintenance and accessibility rather than being a part of the electrical distribution or protective equipment.
