Based on the backup generator fuel type and the connection of this device to the number of other devices in the commercial building, there are some ways by which first requirement of power should be calculated which are inclusive of running the motor individually, simultaneous working of multiple motors and no motors of electric nodes (IEEE Recommended Practice for Emergency and Standby Power Systems for Industrial and Commercial Applications, 1995).. The variation of wattage with respect to appliances has to be considered and based on the calculation of power requirement; the voltage of the backup generator should accordingly be chosen (Appendix 1). However, the regulation of voltage requires maintenance by the use of regulators of voltage. The support of the voltage needs to be enough for maintaining voltage with disconnected generation distribution.
Consideration of Location and Environment
Generators generate excess amount of heat which may damage a particular location if it is not placed appropriately. Environment will also be affected if the placement of generator is not properly measured. Both these concepts will be explained in accordance to factors that should be considered while considering a generator location and the environment surrounding it. Installation of backup generator should be done by considering the requirements of cool air and combustion needed by the generator along with removal of gaseous exhaust (Shirley, 2006). An important consideration is that the location where the backup generator is installed should be distance from other subjects in order to find ways to abate noise generated from the generator. Therefore the location of a backup generator has to be such that the generator is able to stand the extremity of climatic conditions and is able to perform within that condition. Environmental considerations are also important for preventing water source contamination by backup generator fuel and a check list for checking these is important (IEEE Recommended Practice for Emergency and Standby Power Systems for Industrial and Commercial Applications, 1995). The tanks of fuel storage in generators need to be kept over the levels of capable flood water. Other requirements such as keeping the generator in a weatherproof condition is also important and should followed as per the consideration of state. Additionally, a flat surface is needed for placing the backup generator for protecting against any hazardous situations to develop in the work place. The requirement also is to regularly check the generator in order to make sure that the condition is fine.
