Logic4training’s Heavy Duty Cut Out Awareness training course is designed for learners that are experienced Multi Phase meter operatives who wish to gain the awareness, underpinning knowledge and practical skills for Multi Phase meter installations fed from a Heavy Duty Cut Out.
Logic4Training’s 2-day training package gives candidates the awareness, underpinning knowledge & practical skills to work on heavy duty cut outs with J-Fuses and/or cut outs that exceed 100amps per phase.
Learners will undertake learning at our training centre. This enables learners to practice and learn installing and exchanging Multi-Phase Power smart meters from heavy duty cut out in a safe and controlled environment which simulates real work situations.
The training will include the identification of HDCO’s, the risks associated with HDCO’s, the identification of any faults associated with HDCO’s, and fault finding & the testing processes required.
Assessments will include observed practical assessments and theory assessments. In-house certification. In-House Certification – Does not provide authorisation to work on the cut-out (s).
Candidates must be Multi Phase & CoMCoP (formally MOCOPA/SMICOP/SMIS) trained.
Knowledge to work on cut-outs with J-Fuses and/or cut-outs that exceed 100amps per phase:
- The different types of three-phase and heavy-duty cut-outs
- J-Fuses
- Shrouds
- Terminations
- Testing
- Fault identification
- NPg Authorisations
- CT meters summary (Unless qualified, you are NOT permitted to work on CT meters under any circumstances)
- DNO Policies
Health and Safety:
- Confined spaces and the dangers of
- Safe working practices
- Hazardous Situations
- Asbestos
- Carrying out risk assessments to ensure safety of self, others and property
You will gain the required underpinning knowledge and practical skills to work on Heavy Duty cut outs with J-Fuses and/or cut outs that exceed 100amps per phase. In-House Certification – Does not provide authorisation to work on the cut out(s).
Following this course, installers can look to upskill in Gas Smart Meters, Dual Fuel Smart Meters.
FAQs
A Heavy Duty Cut Out (HDCO) is a robust electrical isolation device designed to safely manage high current loads, typically 200A, 400A, or 600A, in commercial and industrial settings. HDCOs are essential for protecting electrical installations, enabling safe maintenance, and ensuring compliance with safety standards.
This course is ideal for electricians, smart meter installers, and engineers working with or near heavy-duty electrical cut outs. It is particularly relevant for those involved in the installation, maintenance, or inspection of smart meters and high-capacity electrical systems.
Modern HDCOs offer:
- Fully insulated construction for enhanced safety
- Multiple cable entry positions
- Captivated external cover screws
- Integrated earth studs
- Removable insulation shields
- Compatibility with both copper and aluminium conductors
- Options for integrated metering chambers
The course covers risk assessment, fault testing, safe isolation procedures, and the correct use of personal protective equipment (PPE) when working with HDCOs. Emphasis is placed on compliance with current UK electrical safety regulations and best practices.
HDCOs are often encountered during smart meter rollouts, especially in properties with higher electrical demands. The course provides essential knowledge for safely working with these units, supporting the UK’s ongoing smart meter installation programme and ensuring installers can handle complex scenarios.
Key risks include electrical shock, arc flash, and equipment damage due to incorrect isolation or handling. The course teaches how to identify and mitigate these risks through proper procedures and safety checks.
