    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 and highways, 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 practical skills like cable jointing, pole erection, and testing, alongside theoretical knowledge of electrical principles, risk assessment, and environmental considerations. The course is hands-on and directly applicable to real-world roles such as street lighting operative or traffic signal technician. It fits within the broader Construction & Building Services sector by supporting the infrastructure that keeps roads safe and functional, linking to civil engineering, electrical installation, and public sector maintenance.

    Mastering this certificate opens doors to career progression, including supervisory roles or further qualifications in electrical engineering. It also emphasises health and safety, which is critical in a high-risk environment like highway works. By the end, students will be competent to work independently on highway electrical systems, contributing to the UK's transport infrastructure.

    Key Concepts

    Core ideas you must understand for this topic

    • →Understanding the requirements of the New Roads and Street Works Act (NRSWA) for signing, lighting, and guarding works on highways.
    • →Knowledge of electrical principles, including voltage, current, resistance, and the application of Ohm's Law in highway electrical circuits.
    • →Safe isolation procedures and the use of test equipment (e.g., multimeters, insulation resistance testers) to verify circuits are dead before work.
    • →Installation techniques for underground cables, including trenching, ducting, and cable jointing to IP68 standards.
    • →Compliance with BS 7671 (IET Wiring Regulations) and the specific requirements for highway electrical installations, such as earth fault loop impedance and RCD protection.

    Learning Objectives

    What you need to know and understand

    • 1. Know how to identify public lighting and traffic sign equipment and highway boundaries2. Know how to identify public lighting circuits.

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for accurately identifying a range of public lighting equipment from photographs, diagrams, or real installations, using correct industry terminology (e.g., lantern, bracket, feeder pillar).
    • Award credit for correctly demarcating highway boundaries on a site plan and explaining the significance of the boundary for electrical work, including ownership and maintenance responsibilities.
    • Award credit for demonstrating the ability to trace and describe the operation of a typical public lighting circuit (e.g., series, parallel, or switched) and identifying key components such as cut-outs, fuses, and photocells.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡When identifying equipment in assessments, use the precise technical names as listed in the Lantra Awards training materials; avoid colloquial terms.
    • 💡For boundary identification tasks, always refer to the red line on provided plans and consider the entire highway extent, including any adjacent land that forms part of the public realm.
    • 💡In circuit identification questions, systematically check for key components (e.g., DNO cut-out, control gear) and state whether the circuit is live or isolated before any work commences.
    • 💡In practical assessments, focus on the sequence of safe isolation: identify the circuit, prove the tester, isolate, lock off, and re-prove dead. Examiners look for methodical adherence to this process.
    • 💡For theory questions, use the correct terminology from BS 7671 and NRSWA. For example, refer to 'protective multiple earthing' (PME) rather than just 'earthing', and mention 'category 1' and 'category 2' works under NRSWA.
    • 💡When answering questions about cable jointing, mention the importance of environmental protection (e.g., using resin joints) and testing after jointing (e.g., insulation resistance > 200 MΩ).

    Common Mistakes

    Common errors to avoid in your coursework

    • Confusing the roles of different lighting equipment, for example misidentifying a traffic sign as a bollard or assuming all columns are feeder pillars.
    • Failing to recognise that highway boundaries may extend beyond the carriageway edge, including verges, footways, and cycle paths, leading to incorrect isolation procedures.
    • Misunderstanding circuit configurations, such as assuming all street lighting is wired in series, or overlooking the importance of identifying the correct circuit for safe isolation.
    • Misconception: 'Highway electrical work is the same as domestic electrical work.' Correction: Highway systems operate at different voltages (e.g., 230V for street lights but also 400V for traffic signals) and involve outdoor conditions, requiring specialised knowledge of weatherproofing, earthing, and NRSWA compliance.
    • Misconception: 'Once installed, highway electrical equipment needs no maintenance.' Correction: Regular inspection and testing are mandatory to detect faults like cable damage, corrosion, or lamp failure, ensuring safety and reliability under the Electricity at Work Regulations.
    • Misconception: 'You can work on live circuits if you're careful.' Correction: Safe isolation is non-negotiable; working live is prohibited unless absolutely necessary and risk-assessed, with proper PPE and permits.
