### Are Generator Interlock Kits Legal in Canada?

For homeowners concerned about the reliability of their power supply, generator interlock kits can seem like a simple and cost-effective option for connecting a generator to household electrical systems. However, the legality of these kits is a complex topic, especially in environments with stringent electrical regulations like in Canada. Are generator interlock kits legal in Canada? Let’s dive in to find out.

#### What Are Generator Interlock Kits?

Interlock kits are designed to prevent generator backfeeding onto the main power grid, which can be dangerous for utility workers repairing power lines and can cause electrical damage. These kits work by physically preventing the main power and the generator from being connected at the same time, ensuring safe operation.

#### Legal Restrictions in Canada

According to guidelines from the Electrical Safety Authority (ESA) and reports from various electrical forums and Q&A platforms like Reddit, the answer is that interlock kits are generally not considered legal in Canada. Here’s why:

1. **Electrical Code Compliance:** The Canadian Electrical Code (CEC) mandates that all electrical installations must meet specific safety standards. According to some respondents on Reddit forums and posts on Electrician Talk, the interlock systems do not meet the requirement for a transfer switch that physically separates the generator from the main power supply by barriers, as stipulated by the CEC.

2. **Approved Transfer Switch Requirement:** The electrical regulations in Canada require the use of an approved transfer switch to safely transition between grid and generator power. So, while installers and enthusiasts might be drawn to the convenience and cost-savings of an interlock kit, these kits do not meet the formal safety and regulatory requirements for generators in Canada.

3. **CSA Approval:** In the United States, interlock kits are generally legal in most states provided they are UL-approved. In Canada, a similar requirement is that the equipment must be CSA-approved for it to be compliant with the Canadian Electrical Code.

#### Understanding the Risks

While legality is a key concern, it is not the only consideration. Improper installation or use of interlock kits can pose significant safety risks, including electrocution, fire hazards, and damage to the generator. For this reason, it’s always recommended to consult with, and ideally hire, a professional electrician who is familiar with the Canadian Electrical Code to install your generator and associated safety equipment.

#### Moving Forward

Given the current landscape, homeowners in Canada are encouraged to follow the CEC mandate and opt for an approved transfer switch instead of an interlock system. The additional cost is justified in the name of safety and compliance.

#### Conclusion

When considering the use of a generator interlock kit in Canada, it’s crucial to remember that while the concept of an interlock may find a home in other jurisdictions, the Canadian Electrical Code mandates a more stringent approach to generator installation and safety. Consult with an electrician licensed in your province or region to determine which safe and legal alternatives are available to you for reliable backup power.

In summary, in Canada, the use of interlock kits may not comply with the Electrical Safety Authority’s approved methods for generator installations, and homeowners are best advised to install approved transfer switches and keep in thorough compliance with local code requirements.
