Generator Installation
Industrial Standby Generator Installation
Setting Generator
A Cummins 1250Â kW generator weighs 25,000 lbs. The facility is equipped with a gantry to support removal and installation of large equipment. Contracting a local crane company to unload generator shifts the responsibility of off-loading and placing the set. Crane will connect to the generator and boom it into facility maintenance door. Maintenance personnel will connect gantry to generator set onto pad.Â
The three generator applications covered are:
• Permanente Enclosed Generator – Outdoor installation of a canopy generator system installation to include, setting and connecting generator and auxiliary fuel system
• Generator Located Inside Factory – Indoor installation of a generator system on a skid. Installation to include setting generator and connection of auxiliary systems.
• Portable enclosed generator – Basic inspection/setup and power system installation diagrams.
Portable Enclosed Generator
Customer is a construction company with a contract for a major addition for a hospital. In the initial stages of construction one portable Baldor 2,000 kW generator set will be required. As the construction reaches final stages a second unit will be needed to support all required services until utilities are connected. Following steps reviewed:
• Inspecting Generator After Transport – Locating and pre-start/pre-load suggestions.
• Electrical Connection – Single and dual generator set ups.
Electrical Connection Options
The configuration requirements for this project require a single generator set for initial stages and in final stages adding all equipment and a second generator to accommodate end of project requirements Always:
• Locate transfer switch in a clean dry area near critical load.
• Provide circuit breaker between generator and automatic transfer switch.
• Adhere to all Federal and Local requirements when designing system.
Single GeneratorÂ
The disconnect switch supplies power to breaker panel. Generator set supplies power to the breaker panel. Breaker panel supplies panel to non-critical equipment and automatic transfer switch.
When critical power is lost, generator starts and automatic transfer switch moves to enable power to be supplied by generator set.
Dual Generator
Project has advanced to the need for a second generator. Two separate generators supplying two separate circuits are needed. This configuration can be considered as a parallel setup. The following describe this set up:
• Generator(s) supply routed through paralleling panel
• Expanded breaker panel to allow for two generators (illustrated as two separate panels).
• Use of two automatic transfer switches allows for separation of loads.
