Design mains failure standby power generation system in accordance with code requirements. Provide sufficient headroom (>2600 mm) in generator rooms for maintenance tasks - i.e., sufficient height to enable any portion of the generating set or equipment to be raised freely for dismantling — in accordance with SS 535, BS 7698-7, ISO 8528-7, NFPA 110 or equivalent. Adopt the general guidelines for earthing of generator sets and substations in accordance with BS 7430, SS 551 or equivalent. For daily diesel service tank package and tank storage (i.e., safety and suitability of design, emergency provisions, and minimisation of vapour hazard), refer to SS 532, BS 5908-1 or equivalent.
Adopt requirements for the construction, installation and testing of generator systems for buildings. Provide sufficient access and clear passage for construction and maintenance. Allotted spaces should be of sufficient strength or suitably strutted to support the loads in accordance with SS 535, BS 7698-7, ISO 8528-7, NFPA 110 or equivalent. Install indoor fuel tank with a level indicator that can be easily accessed for observation. List and mark electrical wiring and equipment located near/within hazardous zones (i.e., day tank) (as defined by NFPA 70 or IEC 60079 SER) for installation in an appropriate manner in accordance with SS 532, BS 5908-1 or equivalent.
Practice proper housekeeping and avoid stacking and storing of combustible materials in the generator house. Maintain records of preventive maintenance activities in a secure manner. Conduct general inspections daily and check on fuel, lubrication and cooling systems. Perform a monthly running of the generator on no load for half an hour. Check battery charger, starting batteries and drive belt tension. Adhere to the requirements for operation and maintenance of standby generator systems for buildings. Once a year, run load test on the generator and check to ensure that emergency supply can support all essential emergency services in accordance with SS 535, BS 7698-7, ISO 8528-7, NFPA 110 or equivalent.
