What voltage do most lighting and power equipment operate at in emergency situations?

Most lighting and power equipment used in emergency situations typically operate at 120-volt AC. This standard voltage is widely used in residential and commercial settings across North America, making it the most accessible and practical choice for emergency lighting systems and equipment. The 120-volt AC power is easily supplied from portable generators or existing electrical systems, ensuring that equipment can be quickly deployed in emergencies to restore lighting and power.

The choice of 120 volts also reflects considerations for safety and compatibility, as it is low enough to reduce the risk of hazardous electric shock while still providing adequate power for most lighting needs in emergency scenarios. This voltage standardization means that firefighters and emergency responders can rely on similar equipment and power sources regardless of their specific location, enhancing operational effectiveness during critical times.
