Electrical Infrastructure

Asmbly's facility is composed of three separate units of 9701 Dessau Road building 3, each of which is equipped with its own "light commercial" 200A 3-phase 120/208V service. Our meters and outdoor disconnects are on the south side of the building around the corner from the laser exhausts.

• The 303 service feeds 200A panel L4 via a main breaker outside. L4 feeds subpanel L3 via a 100A branch circuit breaker.
• The 304 service has a 200A fused disconnect feeding a 200A main panel outside (SP6), which feeds subpanels L2 (via a switch disconnect SW1) and L5 via 100A branch circuit breakers. L5 feeds L6 via a 60 A branch circuit breaker.
• The 306 service has a 200A fused disconnect feeding panel L7 (in the multipurpose room). L7 feeds subpanel L8 via a 100A branch circuit breaker.
