NFPA 110, Standard for Emergency

This standard sets out the requirements for emergency and standby power systems that offer an alternative power source in buildings and facilities when the regular electrical power fails.
These systems include power sources, transfer equipment, control systems, supervisory equipment, and any other necessary accessories to provide electricity to specific circuits.

It helps improve safety for people by making sure emergency power sources are working properly.
It also provides the most up-to-date guidelines for standby and emergency power systems, which supply backup electricity to buildings and businesses when the main power is lost.

Having emergency power available can help protect people during power outages, as explained in NFPA 110, the standard for emergency and standby power systems.

The latest version of the standard covers power sources, transfer equipment, controls, supervisory systems, and all related electrical and mechanical support equipment in detail.
