Electrical Plan Review is not required for which modification criteria?

Electrical Plan Review typically focuses on modifications that significantly impact safety or system integrity. When service loads are increased by more than 5%, this does not necessarily trigger a detailed plan review. Changes of this nature are generally manageable within the existing infrastructure, provided they comply with code requirements and do not compromise the overall performance of the electrical system.

On the other hand, modifications that involve emergency circuits, essential electrical systems, or significant changes like those rated over 400 amps or 250 volts are more critical from a safety and operational standpoint. These situations require careful scrutiny to ensure that the system can handle the new loads and that all safety standards are met, thus warranting a plan review. Therefore, the modification involving a service load increase of more than 5% is considered low risk, and a review may not be necessary.
