How do you select electrical codes for your project?

1 Identify the jurisdiction

The first step is to identify the jurisdiction that applies to your project. This means the country, state, province, city, or county that has the authority to enforce electrical codes. Different jurisdictions may have different or additional requirements than the national or international codes. For example, in the United States, the National Electrical Code (NEC) is the main source of electrical codes, but each state or local government may adopt, modify, or supplement it. You can find out the jurisdiction of your project by contacting the local building department or utility company.

2 Review the applicable codes

The second step is to review the applicable codes for your project. This means the codes that cover the specific aspects of your project, such as the voltage, current, frequency, power, lighting, wiring, grounding, protection, or control. You may need to consult more than one code to cover all the relevant topics. For example, in the United Kingdom, the main source of electrical codes is the British Standards Institution (BSI), which publishes the BS 7671: Requirements for Electrical Installations. However, you may also need to refer to other standards, such as the BS EN 50110: Operation of Electrical Installations, or the BS EN 60204: Safety of Machinery.

3 Compare and comply with the codes

The third step is to compare and comply with the codes for your project. This means to check if there are any conflicts or discrepancies between the different codes that apply to your project, and to follow the most stringent or specific ones. You may also need to obtain approval or certification from the relevant authorities or bodies to verify that your project meets the codes. For example, in Canada, the main source of electrical codes is the Canadian Electrical Code (CEC), but you may also need to comply with the Canadian Standards Association (CSA) or the Underwriters Laboratories of Canada (ULC) standards. You may also need to get a permit or inspection from the local electrical safety authority (ESA) or the electrical contractor association (ECA).

4 Update and maintain the codes

The fourth step is to update and maintain the codes for your project. This means to keep track of any changes or revisions that may affect your project, and to implement them accordingly. You may also need to perform regular testing, inspection, or maintenance of your electrical systems and equipment to ensure they comply with the codes. For example, in Australia, the main source of electrical codes is the Wiring Rules (AS/NZS 3000), but they are updated every few years to reflect new technologies or practices. You may also need to follow the Australian Standards (AS) or the Australian/New Zealand Standards (AS/NZS) for specific aspects of your project.
