AI Commissioning Specialist: Systematic Commissioning, Every Time

The AI Commissioning Specialist is one of eight specialist Elec-AI agents built into the Elec-Mate platform. It is designed to guide electricians through the complete commissioning process for any electrical installation, from a simple domestic consumer unit upgrade to a complex three-phase commercial distribution system.

Commissioning is the critical final stage of any electrical installation. It is the process of verifying that every circuit has been installed correctly, that all protective devices operate within their specified parameters, and that the installation as a whole is safe to energise and hand over to the client. Poor commissioning leads to unsafe installations, failed inspections, and costly return visits. The AI Commissioning Specialist eliminates these problems by ensuring you follow a systematic, standards-compliant commissioning process every time.

Unlike a generic checklist template, this AI agent understands the specific requirements of each installation type. An AI-designed circuit with an EV charger has different commissioning requirements than a standard domestic rewire. A three-phase commercial distribution board requires phase rotation verification and load balance checks that are not relevant to single-phase domestic work. The AI adapts the checklist and guidance to match exactly what you have installed.

The Commissioning Specialist works alongside the other Elec-AI agents. Circuit designs from the Circuit Designer can be fed directly into the Commissioning Specialist, which then generates a commissioning plan that matches the design specification exactly. Completed commissioning results flow into the certification system without re-entering data.

The core capability of the AI Commissioning Specialist is generating tailored commissioning checklists. You describe the installation, and the AI produces a comprehensive checklist covering every verification step, functional test, and documentation requirement.

The checklist follows the initial verification test sequence specified in BS 7671:2018+A4:2026 Chapter 64 and IET Guidance Note 3. This means tests are listed in the correct order: continuity of protective conductors first, then ring final circuit continuity, insulation resistance, polarity, earth electrode resistance (for TT systems), earth fault loop impedance, prospective fault current, and finally RCD operation. The AI also includes pre-commissioning checks such as visual inspection of connections, torque verification on terminals, and confirmation that all circuit identifications are correct.

For specialist installations, the checklist extends beyond the standard initial verification tests. EV charger installations include RCD type verification, load management system testing, and charge point functional testing. Solar PV installations include inverter commissioning, DC string voltage verification, and G98/G99 compliance checks. Emergency lighting installations include duration testing, lux level measurement, and central battery system verification. Fire alarm installations include zone testing, sounder output measurement, and cause-and-effect verification.

Beyond the initial verification tests, the Commissioning Specialist provides detailed functional test guidance for every type of equipment in the installation. Functional testing confirms that the installation not only passes the electrical safety tests but actually operates as intended.

For each functional test, the AI provides: the purpose of the test, the method (step by step), the instrument or procedure required, the expected result for a correctly installed system, and the action to take if the result is outside the expected range. This is particularly valuable for less common installation types where the electrician may not commission that specific equipment regularly.

The AI covers functional testing for consumer units and distribution boards (MCB and RCBO operation, main switch operation, SPD indicator verification), RCD protection (30 mA trip time testing at 1x, 5x, and ramp test), EV charging equipment (charge initiation, load management, earth monitoring), fire alarm systems (zone identification, sounder operation, cause and effect), emergency lighting (changeover testing, duration testing, lux level verification), and specialist installations such as data cabling, access control, and CCTV systems.

The guidance references the correct BS 7671 regulations for each test, so you can verify the AI's recommendations against the standard and cite the regulation on your certification documents.

Proper commissioning documentation is essential for demonstrating compliance and providing a clear record of what was tested and what results were obtained. The AI Commissioning Specialist helps you produce professional commissioning documentation that meets the requirements of BS 7671 and feeds directly into your certification.

The documentation includes a commissioning summary report (listing all tests performed, results obtained, and any observations or remedial items), a schedule of test results formatted to match the EIC or EICR schedule, and a handover pack for the client including operating instructions, maintenance guidance, and a record of the as-installed configuration.

For commercial installations, the documentation extends to include commissioning certificates for specialist systems (fire alarm, emergency lighting, access control), discrimination verification records (confirming that protective devices are coordinated to disconnect the correct circuit in a fault condition), and compliance matrices showing how the installation meets the client specification and the relevant British Standards.

The AI Report Writer can take the commissioning data and produce a professional summary report for the client, translating the technical test results into clear, non-technical language that explains what was tested and confirms that the installation is safe and compliant.

Every aspect of the AI Commissioning Specialist is aligned with BS 7671:2018+A4:2026 and IET Guidance Note 3 (Inspection and Testing, 9th Edition). The AI references specific regulations throughout the commissioning process so you can verify every recommendation against the published standard.

Chapter 64 of BS 7671 sets out the requirements for initial verification, which is the commissioning process for new installations and alterations. Regulation 641.1 requires that every installation shall, during erection and on completion before being put into service, be inspected and tested to verify that the requirements of the Regulations have been met. The AI ensures that your commissioning process covers all the requirements of Chapter 64.

Amendment 4:2024 adds Regulation 530.3.2 covering bidirectional and unidirectional protective devices. For installations with solar PV, battery storage, or other sources of reverse power flow, the Commissioning Specialist includes verification steps to confirm that the installed protective devices are suitable for the direction of energy flow — a critical safety check that older commissioning procedures may not include.

The AI also references the GN3 test procedures and the IET On-Site Guide for practical guidance on test methods, instrument settings, and result interpretation. Every commissioning step includes the relevant regulation number so you can cite it on your certification documentation.
