The AutoCad drawing below is a 2000A, 480V, 3 Phase service we designed
and installed for an existing manufacturing facility. The existing
service was 240V and over time had suffered a substandard evolution.
Critical issues in this installation were to ensure the new equipment
would fit in-between and in place of parts of the existing service,
interfacing the new 480V service with the existing 240V service, and
minimum down time. This was accomplished by taking detailed field
measurements and drawing all components to a .50" tolerance.
