    Lantra Awards Level 2 Certificate in Highway Electrical Work

    Topic Overview

    The Lantra Awards Level 2 Certificate in Highway Electrical Work is a vocational qualification designed for individuals working in or entering the highway electrical sector. It covers the installation, maintenance, and repair of electrical equipment on public roads, such as street lighting, traffic signals, and illuminated signs. This qualification is essential for ensuring that highway electrical systems are safe, reliable, and compliant with UK regulations, including the New Roads and Street Works Act (NRSWA) and BS 7671 (IET Wiring Regulations).

    Students will learn about key topics such as electrical theory, cable jointing, earthing arrangements, and the operation of control gear for discharge lamps and LEDs. The course also emphasizes health and safety practices, including risk assessment, safe digging procedures, and working near live traffic. By the end of the certificate, learners will be able to perform tasks like installing feeder pillars, testing insulation resistance, and troubleshooting common faults in highway electrical installations.

    This qualification fits into the broader Construction & Building Services sector by providing specialized skills for maintaining critical infrastructure. It is often a stepping stone to advanced roles such as Highway Electrical Technician or Supervisor, and it aligns with the requirements of the Street Works (Qualifications and Competence) Regulations. Mastery of this content ensures that students can contribute to safe, efficient, and well-lit road networks across the UK.

    Key Concepts

    Core ideas you must understand for this topic

    • →Electrical theory: Understanding voltage, current, resistance, and power in DC and AC circuits, including calculations using Ohm's Law and power formulas.
    • →Cable jointing and termination: Techniques for connecting and sealing cables in underground and above-ground installations, including the use of resin joints and compression connectors.
    • →Earthing and bonding: Principles of protective earthing, earth electrode resistance testing, and bonding of metallic enclosures to prevent electric shock.
    • →Control gear and lamps: Operation of ballasts, ignitors, and capacitors for discharge lamps (e.g., SON, metal halide) and drivers for LED luminaires.
    • →Health and safety: Risk assessment, method statements, safe digging practices (CAT and genny use), and traffic management (Chapter 8 of the Traffic Signs Manual).

    Learning Objectives

    What you need to know and understand

    • 1. Understand the required steps to install a generic set of typical non-infrastructure equipment used for communications in accordance with manufacturing and/or organisation and legislative policies.2. Understand the required steps to install a generic set of typical non-infrastructure equipment used for variable message signs in accordance with manufacturing and/or organisation and legislative policies.

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for demonstrating a thorough pre-installation check, including verification of structural load capacity, environmental suitability (e.g., IP rating), and correct tooling/PPE.
    • Credit evidence that shows adherence to a method statement and risk assessment, with clear step-by-step documentation of the installation process.
    • Award marks for accurate alignment and orientation of VMS or communication antennas as per design specifications, ensuring clear visibility and signal line-of-sight.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Always reference the manufacturer's installation manual explicitly in your written account – this demonstrates compliance with organisational policies and industry best practice.
    • 💡In your assessment responses, highlight how you applied key legislation (e.g., Working at Height Regulations, Electricity at Work Regulations) to the specific tasks, as this is a common examiner focus.
    • 💡Tip 1: Always reference the latest version of BS 7671 (IET Wiring Regulations) and the relevant British Standards for highway electrical equipment. Examiners look for up-to-date knowledge, especially regarding amendments like the 18th Edition.
    • 💡Tip 2: In practical assessments, demonstrate clear step-by-step procedures for tasks like cable jointing or testing. Show that you understand the 'why' behind each step, not just the 'how'. For example, explain why you clean the cable before applying a resin joint.
    • 💡Tip 3: For written exams, use correct terminology (e.g., 'protective conductor' instead of 'earth wire') and include units in calculations. Show all working out for numerical questions to gain method marks even if the final answer is wrong.

    Common Mistakes

    Common errors to avoid in your coursework

    • Failing to verify the structural integrity of mounting points, leading to potential detachment or collapse under wind loading.
    • Over-tightening fixings, which can damage equipment housings or compromise weatherproof seals.
    • Neglecting to earth metallic enclosures correctly, causing risk of electric shock or equipment malfunction.
    • Misconception: 'LED street lights don't need any maintenance.' Correction: LEDs have long lifespans but still require periodic checks for driver failure, thermal management, and photometric performance. Drivers may fail due to voltage surges or overheating.
    • Misconception: 'Earth electrode resistance doesn't matter as long as there's a connection.' Correction: The resistance must be low enough (typically <20 ohms) to ensure fault current can operate protective devices. High resistance can lead to dangerous touch voltages.
    • Misconception: 'You can use any cable joint for underground connections.' Correction: Joints must be suitable for direct burial, waterproof, and mechanically robust. Using indoor-rated joints can lead to moisture ingress and cable failure.
