Frequently Asked Questions
The 80% rule is a common guideline that recommends running a generator at around 80% of its rated capacity under certain operating conditions, leaving some capacity available for changes in demand. However, the appropriate loading level depends on the generator manufacturer’s specifications, engine type and application. Generators should be sized and operated according to manufacturer guidance to maintain performance and avoid overloading.
Sizing a generator starts with calculating the building’s total power requirements, including essential equipment, lighting, heating, ventilation and other electrical loads. You also need to account for equipment with high starting currents, future demand and whether the generator will provide standby or prime power. GCM can help assess your site’s requirements and identify a suitable commercial generator. Get in touch with us to discuss your requirements.
The best commercial generator depends on your site’s power requirements, operating conditions and intended application. Diesel generators are often used on commercial and industrial sites due to their suitability for standby and prime power applications. GCM supplies commercial generators and provides installation, servicing, maintenance and repair support to meet different business requirements.
The required generator size depends on the building’s electrical load, the equipment that needs to operate during a power outage and whether the generator must support the entire site or only essential systems. Larger buildings and facilities with heavy electrical demands may require higher-capacity generators. Get in touch with us, and a qualified engineer of our team will conduct a load assessment which will help determine the appropriate generator capacity for your building.
