Generator Size Considerations
Generators have varied sizes and shapes depending upon the requirement of commercial buildings. It is believed by most generator users that generators which are smaller in size are better equipped for generating electric power in standby mode because it is not required to work for a longer duration or for whole time. This statement however has a detrimental nature because under-sizing of backup generators has led towards a grave mistake being done by commercial users (IEEE Recommended Practice for Emergency and Standby Power Systems for Industrial and Commercial Applications, 1995). This is further because of the risks involved with regard to generator damage and damages other subjects around the generator leading towards hazardous circumstances to develop and also leading towards limiting complete unit productivity. Therefore in commercial buildings it is better to use larger sized generator backups in order to enhance power generation.
Generator requirement of Voltage
The working principle of a generator has its basis on Voltage requirements and depending upon the required voltage used by a Generator, the machine serves its purpose. It is important that the right wattage should be used while starting the generator for back up or standby purposes and so it becomes crucial for calculating the requirements of accurate power. These requirements are generally present in the manual guide of a generator system with respect to elaborate explanation of voltage need for the device, its tools, application etc. It is required first to convert the requirement of power of the backup generator to watts from Ampere.
Generator related Codes and Standards
Codes and standards related to generators are concerned with human life safety and even environment protection and it is an obligation to abide to these in order to use a generator in buildings for commercial purposes (Shirley, 2006). These codes and standards will be briefly explained to highlight how they serve the purpose of their establishment.
