IEC/EN 60947-7-2, commonly referred to as 16332-2, is an international standard for the protection of electrical devices from transient overvoltages, and other damages that can occur in the distribution and application of electrical energy. 16332-2 applies to the design, installation and maintenance of terminal blocks, or power dividers, which are used in the distribution of electrical energy.

Power dividers are devices that divide electrical current in a given circuit, and allow different components or areas of a circuit to receive different levels of current. They are often used in the distribution of electrical power, and are utilized in many different electrical systems. In order to protect the safety of the components and systems in which it is used, 16332-2 sets out requirements for power dividers, including their function, installation, monitoring, and inspection.

16332-2 outlines the function of a power divider, which includes providing a level of electrical protection that prevents damage caused by transient overvoltages or electric shock, while also ensuring the efficient distribution of electrical power. It states that power dividers should be designed, installed and inspected in accordance with applicable safety and electrical laws, and should be maintained in accordance with all applicable standards and regulations. 16332-2 also states that power dividers should include adequate insulation, circuit protection, fusing, and grounding to ensure proper distribution of electrical current.

It also outlines the installation requirements for power dividers, including that the appropriate junction box and electrical conduit should be used, in accordance with applicable electrical codes and standards. 16332-2 further requires that power dividers should be capable of disconnecting and isolating the circuits in the event of a safety issue, such as an electrical shock.

In addition, 16332-2 requires that power dividers must be regularly inspected to ensure that they are in compliance with applicable safety and electrical codes. Any necessary repairs or modifications should be done in a timely manner, and any damaged or defective components should be replaced immediately. Any changes or modifications to the dividers must be documented, and the appropriate documentation should be kept for future reference.

Finally, 16332-2 requires that regular monitoring should be done to ensure that the power divider is functioning correctly. This may include testing and inspection to ensure that the power divider is providing the required levels of protection, as well as to identify any potential issues or difficulties that may be present. Additionally, it may include testing to ensure that the power divider is able to handle the required current in the event of a power surge or other issue.

In summary, 16332-2 provides guidelines and requirements for the design, installation, and monitoring of power dividers, in order to protect the safety of the components and systems utilizing the dividers, and to ensure the efficient and reliable distribution of electrical power. It is an important international standard, and should be followed in order to protect against potential safety hazards or damages to electrical equipment.
