Introduction:
Generators have become an essential backup source of power for many households and commercial properties. These machines can cater for power outages or emergencies when the electricity grid is not functional. However, an often-overlooked aspect of generator usage is the risks associated with running them when the power comes back on. This risk can result in problems such as damages to the generator, faults in electrical circuits, or even lead to fires. Understanding the risks is important to avoid costly repairs and ensure safety.
Risks associated with power coming on while the generator is running:
When the power comes back on, the electrical circuits will become live. If the generator also feeds into the same circuits, it can cause a backflow of energy into the generator leading to problems. For instance, the electricity can scramble the circuits in the generator leading to electrical surges, motor burnout, and other such faults. Additionally, the unexpected surge can affect the electrical appliances that are running in the house, leading to damages.
Problems with power surges:
One of the most common problems that can occur when the grid and generator become live simultaneously is a power surge. The surge can lead to spikes of electric energy, which can be more than what the appliances can handle. The result is that the electrical equipment can instantly burn out, leading to costly replacements. In some instances, power surges can even cause fires if left unchecked. Therefore, always ensure to turn off all appliances and electrical equipment when using the generator and grid simultaneously.
Damage to the generator:
If the power comes back on while your generator is running, it can cause damage to the machine. The backflow of energy can instantly disrupt the circuits and cause short-circuits, leading to mechanical and electrical faults. These damages can include problems with the carburetor, cylinder heads, engine block, and spark plugs. In worst-case scenarios, it can even cause the generator to become useless as a backup power source.
How to prevent problems with simultaneous use of the grid and generator:
The best way to prevent such problems is to install a transfer switch. A transfer switch ensures that the generator and the grid never become active simultaneously. The transfer switch automatically switches off the grid when the generator is turned on, ensuring that the circuits are only fed by the generator. In turn, the switch also ensures that when the power comes back on, the circuits are still powered by the grid.
Importance of a transfer switch:
Having a transfer switch is incredibly important for the safety and reliability of your generator. It ensures that only one source of power is active at a time, preventing any chance of damage or electrical surge. The switch also ensures that the generator runs efficiently without any risks of overloading or problems caused by power surges. In the end, spending a little extra for a transfer switch can save you a lot of money and problems in the long run.
Conclusion:
In conclusion, no matter how good your generator is, problems can occur when the grid comes back on while the generator is running. It can lead to damaged circuits, problems with the generator, and also cause problems with your electrical equipment. Therefore, it is vital to keep in mind the risks and invest in a transfer switch to prevent such problems. With a transfer switch, you can rest assured that your generator will be a reliable source of power during emergencies.

Frequently Asked Questions: What Happens If Power Comes On While Generator Is Running?
1. What happens if power suddenly comes back on while the generator is still running?
If the generator is still running when the power comes back on, there is a chance that it could cause a power surge that may damage your home’s electrical system, appliances, or electronics. This is why it is important to have an automatic transfer switch installed to prevent this from happening.
2. Is it safe to have the generator running when power comes back on?
No, it is not safe to have the generator running when power comes back on. The sudden surge of electricity can cause damage to your appliances and electrical system. It is important to have an automatic transfer switch installed to avoid this situation.
3. What is an automatic transfer switch, and why is it important?
An automatic transfer switch is a device that automatically switches the power supply from the generator to the main power source when it detects that the power has come back on. It is important because it prevents the generator from running when the power comes back on, which can cause damage to your electrical system and appliances. It also ensures that your home’s power supply is always uninterrupted.
4. How do I install an automatic transfer switch?
Installing an automatic transfer switch should be done by a licensed electrician. They will be able to determine the appropriate size of the switch for your home and install it correctly. It is not recommended to attempt to install an automatic transfer switch on your own, as it can be dangerous and may void your home insurance if not done properly.
