Is your business prepared for operating in the event of a power outage? Procuring a power generator protects your business from screeching to a halt if the power goes out – helping you to keep your staff and customers happy, without skipping a beat.

What Is A Power Generator

Power generators are stand-alone providers of backup power, should the main source of electricity fail for any reason. Much like a vehicle, generators create mechanical energy using heavy-duty rechargeable batteries for storing and maintaining power. Power generators also use dedicated fuel tanks to operate, as well as an engine and an alternator.

Why having a generator is smart for your business:

  • If or when the power goes out, you can maintain productivity without skipping a beat
  • Security systems and computer equipment can continue to function in the event of a power outage, protecting your business’s data and contents
  • Standby power supply is uninterrupted, despite power outages, which means business can continue to run as per usual, without losing valuable time

Types Of Commercial Generators

Portable Commercial Generator


Supplying power to a few chosen essentials such as lights and refrigerators, portable generators can be plugged into appliances using extension cords, or wired into a sub-panel by an electrician. These are less expensive, simple options for backup power supply in the event of a power outage.

These generators must be manually started to supply power during a power outage, and their operation must be manually maintained, i.e. by topping up the fuel tank. These units must be placed 3-5 meters away from your building, far from any windows or doors, and used in a completely open area with good air flow to avoid carbon monoxide buildup.

Standby Commercial Generator


Standby generators switch on automatically when the power goes out, preventing interruptions to your productivity. These generators are also fuel-powered. While standby generators cost more than portable generators, they are quieter and can supply power to everything in your building during a power outage. A standby generator must be installed by an electrician, including the installation of a transfer switch and sub-panel.

Potential Issues

  • Battery failure: This is the most common cause for power generators requiring a service. Battery failure may result from sulphate buildup on the terminals, shorting, tripped charger breakers, charger failure, open cells or loose or dirty connections.
  • Low coolant: External and internal leaks and clogged radiators, amongst other things, can cause a power generator to run too hot and consequently shut down.
  • Controls not in “auto”: This means that the power generator was not shut off and may not be the main control switch. This can result from many things, such as human error, open breakers, alarms and emergency shut down.
  • Air in the fuel system: The presence of air in your generator’s fuel system can prevent the injectors from firing, and is typically caused by the engine not being run on a regular basis. Weekly inspections can prevent this potentially costly occurrence.
  • No fuel: To prevent the fuel system from drawing in air, generators will automatically shut down when the fuel tank is almost empty.
  • Breakers tripping: Check first to see if this was caused by someone accidentally flipping the emergency shut-off switch. If not, check the status of the automatic transfer switch (ATS). You should never try to manually operate this switch if you do not know how to, because doing so could result in severe injury or even death.

Warning: Never plug your generator into a wall outlet (‘plug’). This is known as ‘backfeeding’, and if done without first isolating your building from the grid, you could potentially injure or kill utility repairmen by sending power back on into the grid.

Professional Generator Installation

A trained professional can determine the right size generator to suit your requirements.

Do you know how to calculate wattage properly so that your system isn’t overloaded on startup? This amount varies depending on the equipment being powered, as well as the specifications of the generator. Our technicians are qualified professionals that possess the skills necessary to calculate power needs for safe, seamless operation.

Professional generator installation are safer.

Safe setup of wiring, connection to the transfer switch and direct wiring to the service panel can and should only be done by a trained, qualified electrician. This ensures that you are properly disconnected from the grid, which makes for safe delivery of power to only those designated circuits and prevents a range of hazards. Failure to disconnect properly from the grid while your generator is running can cause backfeeding, generator overload, fire, carbon monoxide poisoning and more.

At sunburst Electric, we arrange for your newly-installed generators to be inspected, ensuring that safety regulations are met. With the help of a power generator, you can keep your business operating seamlessly in the event of a power outage.
