for this Lab you will be laying out and installing an emergency service panel. Emergency service panels have requirements for their installation and use and there are multiple types of installation for emergency (standby) services. Answer the following Questions: 1List the requirements for a general emergency service. Where is a general emergency service installed? 2. What are the allowed systems for emergency power generation that the NEC recognizes?

(1) General Emergency Power Systems provide automatic backup power in the event of normal power loss. They are required by code and shall provide power within 10 seconds to all life safety systems such as egress lighting, smoke evacuation, fire alarm systems, elevators, etc. Simply put, anything that will protect the lives of the building occupants should be on Emergency Power. Another important thing to remember is that emergency power systems must be completely separate; this means that they shall have their own conduit runs, their own panels, their own transfer stations, etc. A backup power system should be designed to provide electricity to only the most important pieces of equipment in a building. It is not cost effective to have backup power available for every electrical component in a building. Most facilities, even the most critical, can be ramped down during an outage so that fuel or battery power can be conserved.Life safety systems are always required to be on an Emergency Power System. This includes lighting of egress paths, power for sprinkler pumps, and power to fire alarm systems. Hospitals will put life-saving equipment, like respirators, on standby power. Fire and Police Stations will make sure that their radio systems are on standby power so they can manage operations during emergencies.Homeowners are free to size their standby generators to meet their needs. Refrigerators, freezers, and sump pumps are normally on circuits tied to the backup system, as are lights throughout the home. A few convenience outlets are also put on the system to allow phones to be charged and to keep a television or radio operational during major outages. Fuel storage capacity tends to be the limiting factor for the size of a home generator you want to have enough fuel to keep the system operational through the outage; therefore, many of life's conveniences are turned off to conserve fuel.
