Surface-mounted wiring is frequently employed for its practicality and convenience in installation and maintenance. This method allows for wiring to be easily accessed without the need for extensive wall alterations, which is especially beneficial in renovation projects or where wall space may be limited. Surface-mounted wiring is also a quicker installation option that does not require the labor-intensive processes involved in concealing wires within walls, making it a cost-effective choice for temporary setups or in areas requiring frequent changes. In contrast, concealed wiring is predominantly designed for aesthetic purposes and to protect wiring from physical damage, but it doesn't facilitate easy access. Underground wiring is focused on safety, particularly in protecting cables from weather-related damage and reducing hazards associated with surface mounted wiring but does not address the ease of installation. Lastly, while flexible wiring can help in avoiding damage in certain applications, it does not specifically relate to the common practice of surface mounting where easy access is the primary benefit.
