What You'll Learn
Electrical equipment that doesn't require NRTL approval
The Nationally Recognized Testing Laboratory (NRTL) is a certification that electrical equipment must have to be considered "approved" in the United States. This requirement is set forth by the Occupational Safety and Health Administration (OSHA) and is mandated for electrical equipment to be "approved" at 29 CFR 1910.303(a).
However, there are some exceptions to this rule. For example, custom-made equipment designed and fabricated for a particular customer does not need NRTL approval as long as its manufacturer determines it is safe for its intended use. This determination must be based on test data that the employer keeps and makes available to the Assistant Secretary of Labor for OSHA.
Additionally, electrical equipment that is not accepted, certified, listed, labelled, or determined to be safe by an NRTL may still be acceptable to OSHA if it is inspected or tested by another Federal Agency or a State, municipal, or local authority responsible for enforcing occupational safety provisions. This authority must ensure compliance with the National Electrical Code (NEC) and the relevant Subpart S of 29 CFR 1910 standards.
It is also worth noting that while NRTL approval is a requirement for equipment to be considered "approved", the term "approved" in OSHA standards addressing electrical hazards is defined as "acceptable to the Assistant Secretary of Labor for Occupational Safety and Health".
Furthermore, some states and cities have their own requirements for electrical equipment. For example, Washington State requires that all equipment that plugs in be tested by a Washington-approved testing agency. On the other hand, some states may only require NRTL listing for the electrical parts of a machine, not the entire machine.
Therefore, while NRTL approval is generally required for electrical equipment in the United States, there are certain situations and exceptions where it may not be necessary. It is important for manufacturers and vendors to be aware of the specific requirements and standards applicable to their products and locations.

NRTL approval for custom-made equipment
The United States Occupational Safety and Health Administration (OSHA) requires that certain products be "approved" by a Nationally Recognized Testing Laboratory (NRTL). This is to ensure that employers provide a safe working environment for their employees.
Custom-made equipment that is designed, fabricated for, and intended for use by a particular customer does not need to be approved by an NRTL if it is determined to be safe for its intended use by its manufacturer. This determination must be based on test data that the employer keeps and makes available to the Assistant Secretary of Labor for OSHA.
However, even if custom-made equipment is not required to be approved, it still may not be used if it poses a hazard to employees. For example, if it presents an ignition hazard, it cannot be used.
To obtain NRTL approval for custom-made equipment, manufacturers can work with certification experts to minimize the time and costs of the process. This typically involves identifying the applicable UL/CSA standards for the product, conducting an on-site assessment during an initial factory inspection, and providing a conclusive report with modification suggestions.
It is important to note that electrical products intended for sale in the United States must comply with Underwriters Laboratories (UL) standards, while those placed on the Canadian market must meet the standards outlined by the Canadian Standard Association (CSA).

NRTL marks and certification
A Nationally Recognized Testing Laboratory (NRTL) is a body that evaluates, tests, and certifies electrical equipment to ensure it complies with safety standards. NRTLs are recognised by the Occupational Safety and Health Administration (OSHA) in the United States and by the Standards Council of Canada (SCC). There are currently 17 accredited NRTLs across the two countries.
Electrical products intended for sale in the US must comply with Underwriters Laboratories (UL) standards, while those for the Canadian market must meet Canadian Standard Association (CSA) standards. Products that bear the mark of an NRTL are deemed safe for the US market and are in compliance with the relevant safety standards.
The process of obtaining NRTL certification typically involves a factory inspection, product and safety testing, and a review of the safety testing report by a technical certifier. If the product passes the tests, the certifier issues a certificate. Regular factory surveillance is then conducted to maintain the certificate's credibility.
While NRTL certification is not required for all products in the US, it is crucial for certain products, especially electronics, to gain access to the market. OSHA has identified 18 different types of products that require NRTL certification. In addition, many agencies, including OSHA, require equipment to be NRTL-approved.
It is important to note that custom-made equipment designed and fabricated for a particular customer is exempt from NRTL certification. However, it must be determined to be safe for its intended use by its manufacturer, based on test data that must be kept and made available to the Assistant Secretary of Labor for OSHA.

NRTL approval for products sold in the US and Canada
Nationally Recognized Testing Laboratories (NRTLs) are independent laboratories that test and certify electrical products for the North American market. NRTLs are accredited by the United States Occupational Safety and Health Administration (OSHA) and the Standards Council of Canada (SCC) to ensure products meet safety standards.
In the US, OSHA imposes duties on employers to ensure a safe working environment for employees. To do this, certain products must be "approved" by an NRTL. Employers, retailers, and customers expect applicable products to be compliant with OSHA rules. NRTL approval is required for products installed in new commercial locations. However, there are exceptions for products with limited production runs where the cost of NRTL approval would be prohibitive.
Electrical products intended for sale in the US must comply with Underwriters Laboratories (UL) standards, while those for the Canadian market must meet Canadian Standard Association (CSA) standards. Products that bear the mark of an NRTL recognised to test and certify these standards are deemed compliant with the required standards of the North American market.
The process of obtaining NRTL approval typically involves the following steps:
- NRTL preliminary investigation during the product design stage
- Technical documentation, including critical component lists, certificates, datasheets, and insulation diagrams
- NRTL testing, which must be OSHA-recognised and conform to OSHA rules
- NRTL certification, which allows the manufacturer to apply a registered certification mark to the product
- Periodic factory surveillance, with regular check-ins by NRTL surveillance teams
Obtaining NRTL approval can be a daunting task, but working with certification experts can help minimise the time and costs involved in the process. These experts can guide you through the entire procedure, from the initial engineering review to the official conformity assessment, ensuring your product gains market access in the US and Canada.

NRTL approval for products used in the workplace
Nationally Recognized Testing Laboratories (NRTLs) are independent, third-party organizations recognized by the Occupational Safety and Health Administration (OSHA) to evaluate, test, and certify products for safety. NRTLs play a crucial role in ensuring that products meet regulatory requirements and are safe for use, especially in the workplace.
OSHA's standards for certain products mandate NRTL testing and certification. These products are typically used in the workplace, as OSHA aims to ensure employers provide a safe working environment. When OSHA legislation states that a product must be "approved", "certified", "listed", "labeled", or designated a test standard, NRTL approval is required.
Electrical products intended for sale in the United States must comply with Underwriters Laboratories (UL) standards, while those for the Canadian market must meet Canadian Standard Association (CSA) standards. Products must bear the mark of an NRTL to demonstrate compliance with these standards.
The NRTL approval process involves several steps, from the initial stages of product design to the final product. Manufacturers and importers should engage with NRTLs to ensure their products meet the necessary safety standards. NRTLs provide third-party verification of product safety, which is essential for manufacturers to ensure their products are safe for use and comply with regulatory requirements.
It is important to note that not all electrical equipment requires NRTL approval. Custom-made equipment designed and fabricated for a specific customer is exempt from this requirement if the manufacturer determines it is safe for its intended use based on test data. Additionally, equipment that has been inspected or tested by another Federal Agency or local authority and found to be in compliance with the National Electric Code (NEC) and OSHA standards may be acceptable without NRTL approval.
