When must a service disconnect be accessible?

A service disconnect must be accessible and within sight of the electrical service equipment to ensure that, in case of an emergency or for routine maintenance, it can be quickly and easily operated. This requirement enhances safety by allowing personnel to swiftly disconnect power in hazardous situations, such as during a fire or electrical fault. Accessibility ensures that individuals working on the electrical system can reach the disconnect without obstacles.

While other choices might suggest various scenarios regarding accessibility, they do not meet the critical safety requirement established by codes and standards. It is important for service disconnects to be not only accessible but also within sight, which reinforces the safety and efficiency of electrical work, thereby preventing potential accidents.
