When electrical equipment is exposed to heat, fire residue, or firefighting activities, it can become hazardous if re-energized without proper evaluation. The National Electrical Manufacturers Association (NEMA) guide provides critical insights for assessing such damage and determining next steps.

This guide may be especially useful for evaluating damage in wildfire-stricken areas of Los Angeles. Based on past wildfire experiences in Northern California (e.g., Paradise Camp Fire, Santa Rosa, and Napa fires), most structures are often incinerated beyond salvage, but some may still be recoverable. The NEMA publication offers guidance for these cases.

Thorough evaluation, consulting manufacturers, and adhering to safety protocols are essential for ensuring safe operation. For detailed tables, specific equipment guidance or any additional questions, please visit NEMA’s website.
