This outage on Sunday, October 31st 7-11am is the second of three outages necessary to perform routine maintenance and testing of the main electrical switch gear, serving CSRB. This outage is mainly on 480/277V equipment and lighting power and should not affect normal receptacle power in the lab spaces. However, any emergency lighting and equipment connected to red emergency receptacles in the South & Center sections, (all floors), may experience a power blip when the normal power is turned off. These emergency receptacles and emergency lights will have power restored once the generator starts and picks up the load. This should only affect the emergency outlets and emergency lighting in the South & Center sections of the building (all Floors). All normal power 120/208V receptacles and equipment should remain unaffected by this outage. This outage will also affect the air handling equipment and exhaust equipment serving these areas. While some of this equipment is on emergency power, not all of it is. Users should expect fluctuations in airflow and exhaust during this time.
