Residential Electrical Wiring Code Ontario

The Residential Electrical Wiring Code (REWC) is a set of rules and regulations that govern the installation of electrical wiring in residential buildings in Ontario. The REWC is designed to protect the safety of people and property by ensuring that electrical installations are done in a safe and efficient manner.

The REWC is administered by the Electrical Safety Authority (ESA). The ESA is responsible for enforcing the REWC and issuing permits for electrical work. The ESA also provides training and education on electrical safety.

The REWC is divided into two parts: the General Requirements and the Supplementary Requirements. The General Requirements apply to all electrical installations, while the Supplementary Requirements apply to specific types of installations, such as swimming pools and spas.

The REWC is a complex document, and it can be difficult to understand for the layperson. However, it is important to understand the REWC if you are planning to do any electrical work in your home. If you are not sure about the requirements of the REWC, it is always best to consult with a qualified electrician.

The REWC is updated regularly to reflect new technologies and safety standards. The most recent edition of the REWC was published in 2018.

If you are interested in learning more about the REWC, you can visit the ESA website at www.esasafe.com. The ESA website has a wealth of information on electrical safety, including the full text of the REWC.

The REWC is an important part of ensuring the safety of electrical installations in Ontario. By following the REWC, you can help to protect yourself, your family, and your property from electrical hazards.
