Lighting and power equipment at an emergency scene generally operates at which electrical system?

Explanation:
Lighting and power equipment at an emergency scene generally operates at 110-volt AC. Most portable lights, extension cords, and power tools responders use are designed for 110V AC, and portable generators at incidents typically supply 110–120V AC single-phase. This alignment makes equipment readily available, simplifies distribution through standard outlets, and allows transformers to adjust voltage if higher or lower power levels are needed. DC systems aren’t the standard for general scene lighting, and while higher-voltage setups like 220V AC exist for certain heavy equipment, they’re not the typical choice for lighting and everyday scene power.
