When must drawings for feeder installations be submitted?

Submitting drawings for feeder installations before beginning the installation is essential because it ensures that all necessary planning, compliance, and coordination can take place upfront. These drawings typically provide critical information regarding the layout, electrical load calculations, and the specifications of the feeder system which need to be reviewed and approved by relevant authorities or stakeholders beforehand. This early submission helps in identifying potential issues or necessary modifications before any physical work begins, thus avoiding delays and ensuring that the installation adheres to codes and standards.

Timely submission of drawings can also facilitate better communication with inspectors, engineers, and other trades involved in the project, ensuring that everyone is aligned on the project requirements and execution plan. Overall, having the drawings approved ahead of the installation process lays a solid foundation for a successful and compliant electrical installation.
