Electrical Systems

Abstract

Considerable lead time is required in giving formal notification to the local electrical utility to allow their engineering staff to plan and design the system with the capacity to serve the proposed winery. The winery’s principal electrical design engineer generally coordinates the master electrical service plan and obtains from the other design professionals involved in the project relatively firm estimates of the electrical load that their respective subsystems will require. It is not uncommon to have separate electrical engineering design subcontractors for the main service and winery building, for the site utilities, and for the landscaping (irrigation control systems and lighting). As this request has to be made anywhere from 4 to 6 months before final plans and specifications are complete, some oversizing of the electrical service requirements is made to cover any design shortfall that may occur because of special electrical equipment for which current and voltage requirements could not have been anticipated. A typical format for an electrical service application is shown in Table 2.1.
