This outage will affect all 208/120V receptacle and lighting power on all floors of BTC. All normal receptacle and lighting power will be off for the duration of this outage. The generator will run to provide power to any receptacles, lighting and critical equipment connected to the emergency power system. The purpose of this outage is to perform maintenance and testing on the main electrical switchgear that distributes 208/120V power throughout BTC. We will also be performing maintenance on some of the 4160V distribution equipment that is in line with BTC, EAS, & EIR. This requires de-energizing the necessary switchgear so that we can safely and effectively perform the required work. This work will ensure that our main electrical systems will continue to provide safe and reliable power.
