The 277/480 Volt, 3 phase, 4 wire, electric services extend into the 45 and 50 Foundation Avenue buildings from the secondary side of two 2,500KVA Utility Company pad mounted transformers and terminates on the line side of a 4,000 Amp main circuit breaker in main switchboard MDP in each building. Power is distributed throughout each building through multiple downstream panelboards and dry type transformers. This study includes all major electrical equipment from the pad mounted transformer to downstream panelboards.
