The 18th edition of the IET Wiring Regulations, otherwise known as the “Consumer Unit,” came into effect on January 1, 2019. If you are a business owner who is not up to date on the changes, now is the time to catch up! In this blog post, we will discuss some of the most important changes that have been made to the regulations. We will also provide tips for making the switch to the new consumer unit.

The 18th edition consumer unit has seen a significant overhaul compared to the 17th edition. Most notably, there have been updates to requirements for residual current devices (RCDs). These require all circuits in domestic properties to be protected by an RCD with a rating no higher than 30mA. This is an important safety measure that can help prevent electric shock and damage from overloads or short circuits.

Additionally, new rules have been introduced regarding isolation switches and socket-outlets for showers, which must now be of the double-pole type. There have also been changes focusing on surge protection and earth-fault loop impedance testing. Furthermore, installation companies must now adhere to Part 7 when carrying out certain electrical installations, such as socket outlets, lighting points, and switches.

In addition to these changes to the wiring regulations, other updates include the introduction of new fire safety requirements. These cover areas such as emergency escape lighting, door release systems and smoke detectors. The Regulations have also been extended to include photovoltaic panel installations and heat pumps.

Overall, it is important that all electrical installation work complies with regulatory requirements in order to ensure safety for both people working on the job, as well as those using the electricity in their homes or businesses. It is essential that electricians stay up-to-date with any changes made by the IET in order to remain compliant and protect their customers from danger. By following these regulations, they can ensure the safety of their customers and all who may come into contact with their electrical systems. In addition, professional electricians should also consider additional safety measures such as regular testing and maintenance to further reduce the risk of any potential hazards.

Ultimately, being compliant with IET Regulations is extremely important for electricians in order to protect themselves, their customers and anyone else who may come into contact with their work. Failure to comply could lead to serious injury or worse and so it is essential that all electricians remain up-to-date on any changes made by the IET. By following these regulations, electricians can ensure safety for everyone involved and provide peace of mind for those using their services. 18th edition consumer unit
