I am unable to view images of codes or advertisements. Therefore, I cannot verify whether what you saw is code-compliant. To determine code compliance, you need to consider several factors: What electrical codes are relevant in your area? In the US, the National Electrical Code (NEC) is widely adopted, but local municipalities might have amendments. The specific application

What exactly is the device or wiring being used for? The code requirements will vary depending on whether it's for general lighting, outlets, appliances, or something else.

Installation

Even if the device itself is listed, improper installation can make it non-compliant.

General Advice



Look for Listing

Electrical products should be listed by a recognized testing laboratory (like UL, ETL, CSA, etc.). The listing mark indicates that the product has been tested and meets safety standards. The specific listing mark and standard to which it's been tested will depend on the type of product.

Read the Instructions

Always follow the manufacturer's installation instructions. These instructions are part of the listing and are crucial for safe and compliant installation.

Check with Your Local Authority

The best way to ensure compliance is to contact your local building department or electrical inspector. They can provide guidance on the specific requirements in your area and may require permits and inspections for certain electrical work.

Consider Hiring a Qualified Electrician

If you are unsure about any aspect of electrical work, it's always best to hire a licensed and qualified electrician. They have the knowledge and experience to ensure that the work is done safely and in accordance with the applicable codes.

To provide more specific advice, please provide more information about the product or wiring you saw advertised. For example



What is the product? (e.g., a specific brand of smart outlet, a type of extension cord, a DIY wiring kit) What is it designed to do? What claims are they making about it? Does it have any listing marks (UL, ETL, etc.)? Can you provide a link to the product or advertisement?

With more information, I can give you a more informed opinion, but I still can't guarantee compliance without knowing your local codes and seeing the product in person. Flag for review
