Diverted Neutral Current (DNC) and Net Currents (NET)

Who is the course for?

This course is essential for electricians, electrical apprentices, and anyone involved in the installation, maintenance, or inspection of electrical systems. This course is crucial to understand the risks posed by diverted neutral current (DNC) and net currents (NET), which can lead to unsafe conditions and equipment failure.

Why attend the course?

Through this one-day session, attendees will learn how to identify, manage, and mitigate these potentially hazardous currents. Whether you’re just starting your career or you’re an experienced professional looking to refresh your knowledge, this course provides practical insights into recognising and addressing the dangers of DNC and NET currents, helping you work more safely and effectively.

By attending, you will:

• Understand the risks associated with DNC and NET, including how they develop, what they indicate, and why they are dangerous.
• Learn how to recognize warning signs before they escalate into fire risks, electric shock hazards, or costly equipment damage.
• Gain confidence in identifying unsafe installations or legacy issues that may have gone unnoticed in your workplace or on-site.
• Improve safety and compliance by understanding your legal responsibilities under regulations such as the Wiring Regulations (BS 7671) and the Electricity at Work Regulations.

This practical, one-day course is perfect to help improve electrical safety, reduce risk, and stay ahead of potentially serious issues—before they cause harm.
