Surge Protection

Who is the course for?

This one-day course is ideal for electricians, electrical contractors, designers, and inspectors involved in domestic, commercial, or industrial installations. If you are responsible for specifying, installing, or maintaining electrical systems, understanding surge protection is essential for compliance and safety.

The course is particularly suited to those who want to better understand overvoltage risks—including lightning-related surges and the correct selection and application of Surge Protective Devices (SPDs). It covers key standards such as BS 7671, IS10101, and introduces BS EN 62305 (protection against lightning), making it valuable for professionals wanting to stay current with regulations.

Attendees will also benefit from practical guidance on testing SPDs, common installation errors, and how the absence of surge protection can impact EICR coding. Whether you’re new to surge protection or looking to refresh and expand your knowledge, this course offers essential insights to help you work safely, compliantly, and with confidence.

Why attend the course?

Surge protection is no longer optional—it’s a vital component of modern electrical safety and compliance. This one-day course equips electricians, contractors, designers, and inspectors with the essential knowledge to understand, apply, and test Surge Protective Devices (SPDs) effectively. With growing risks from overvoltage events—including those caused by lightning—and increasing scrutiny under standards like BS 7671, IS10101, and BS EN 62305, staying informed is critical.

You’ll gain practical insights into selecting the right SPDs, avoiding common installation mistakes, and ensuring your work meets regulatory and safety expectations. You’ll also learn how surge protection affects EICR assessments, making this course a must for those who want to future-proof their installations and protect clients’ assets. Whether you’re updating your knowledge or tackling surge protection for the first time, this course delivers the clarity and confidence you need.
