Introduction:
Generators have become an essential part of many households and businesses. They are used in times of power outages or as a backup power source. However, generators can be dangerous if not used properly, and they pose significant risks to both humans and equipment. That’s why interlock devices have been introduced to ensure the safe operation of generators. In this article, we will discuss what an interlock does for a generator, and why it is important.
What is an Interlock?
An interlock is a safety device that is installed in a generator to prevent it from operating while the main power is still connected. It ensures that the generator is not connected to the main power grid when it is operating. An interlock works by disabling the main circuit breaker that connects the generator to the power grid. This feature ensures that the generator does not feed power back into the grid, which can result in electrical shocks or fires.
How Does an Interlock Work?
An interlock device works by mechanically preventing the generator from being connected to the main power when the generator is generating electricity. The interlock only allows the generator to be connected to the electrical system when there is no power or when the main power is unavailable. This feature ensures that the generator can be safely used during emergencies, and does not pose a risk to the user or the equipment.
Benefits of Using an Interlock
There are several benefits of using an interlock device with your generator. Some of them are:
1. Safety: Interlock devices ensure the safe operation of your generator. They prevent electrical shocks and fires that can occur due to improper connections.
2. Cost-Effective: Interlocks are a cost-effective solution for ensuring the safe operation of your generator. They are easy to install and maintain and can save you money on potential damage to your equipment.
3. Compliance: Interlock devices are widely accepted by regulatory bodies such as OSHA (Occupational Safety and Health Administration) and NEC (National Electric Code). By installing interlock devices in your generator, you can ensure that you comply with the relevant regulations.
4. Convenience: Interlock devices are easy to use and do not require any special skills or training. They provide a quick and convenient solution for ensuring the safe operation of your generator.
Conclusion
In conclusion, an interlock device is an essential safety feature that should be installed in every generator. It ensures the safe operation of your generator and prevents electrical shocks and fires that can occur due to improper connections. Interlock devices are cost-effective, compliant, convenient, and easy to use. They are the best solution for protecting your equipment and ensuring the safety of your home or business during power outages.

Frequently Asked Questions: What Does An Interlock Do For Generator?
What is an interlock for a generator?
An interlock for a generator is a device that prevents backfeeding of power to the grid during an outage. It is a safety mechanism that ensures that the generator does not accidentally supply power to outside power lines or transformers that could harm utility workers.
How does an interlock work for a generator?
An interlock works by ensuring that the generator and the electrical panel cannot be connected to each other at the same time. It is done by installing a mechanical interlock between the generator breaker and the main breaker in the electrical panel. When the main breaker is on, the generator breaker is off and vice versa.
Do I need an interlock for my generator?
It is highly recommended to install an interlock for your generator if you want to use it to power your home during an outage. Without an interlock, you risk backfeeding electricity into the grid and endangering utility workers who are trying to restore power. Also, using a generator without an interlock invalidates your home insurance policy in most cases.
How much does it cost to install an interlock for a generator?
The cost of installing an interlock for a generator depends on several factors such as the type of interlock, the size of your electrical panel, and the complexity of the installation process. A basic interlock could cost around $150-$250, while a more advanced system could cost up to $500-$600. It is recommended to consult a licensed electrician to get a precise estimate for your specific needs.
