Where should cable limiters, meters, and meter disconnect switches typically be positioned?

The correct placement of cable limiters, meters, and meter disconnect switches is on the load side of the service disconnecting means. This positioning is crucial for several reasons.

Firstly, placing these components on the load side allows them to effectively monitor and control the electrical load that is being supplied to the premises. This is essential for ensuring that the electrical system operates within its designated parameters, preventing overloads and allowing for proper metering of the electricity consumed.

Furthermore, having these devices on the load side of the service disconnecting means provides a level of safety. In the event of an electrical fault or maintenance work being performed, the service disconnect can be utilized to safely isolate the entire system. This ensures that when accessing meters or disconnect switches, personnel are working in a safe condition, as the flow of electricity can be confidently controlled.

Other placements, such as on the output side of a generator or before the service disconnect, can lead to complications in safety and functionality. For instance, positioning them before the service disconnect might expose them to potential hazards because they wouldn’t be able to safely isolate the load during maintenance. Similarly, positioning them exclusively in the service entrance area could limit accessibility and not align with typical installation practices, which aim for efficiency and safety
