Where should the service equipment disconnect for a manufacturing building be installed?

The service equipment disconnect for a manufacturing building should be installed at a readily accessible location, either inside or outside, nearest the point of entrance of the service conductors. This is important because the disconnect must be easily accessible for operators or emergency personnel to quickly shut off the power in case of an emergency, maintenance, or other operational needs.

Placing it close to where the service conductors enter the building ensures that it can be easily reached without having to navigate through various layouts or obstacles that may exist within the building. This location minimizes potential delays during emergencies when quick access to power disconnect is critical.

Other options suggest locations that could hinder accessibility or operational efficiency. For instance, installing it at any location within the building might lead to difficulties in reaching the disconnect in urgent situations. Being close to the utility transformer may not provide the necessary accessibility and could complicate safe operation. Likewise, while placing it at the main entry point might seem practical, the ideal location needs to be specifically near the service conductors for optimal functionality.
