Marine Vessel Electrical Installation and AC Circuit Conditioning.

At DJB Electrical, we provide expert marine electrical services, specialising in the inspection, testing, and installation of AC circuits on private and commercial vessels. Our Electrical Installation Condition Reports (EICR) and full AC installation services ensure that all onboard electrical systems are safe, compliant with current marine standards, and reliable for operational use in harsh marine environments.

Polar Bound Marine Vessel

Vessels Serviced – Polar Bound, Corinthian, Geist

We recently carried out comprehensive electrical inspections and installations on three notable yachts:

Polar Bound Marine Vessel

Polar Bound

A high-performance sailing vessel with complex AC and DC distribution systems requiring full thermal imaging analysis of main switchgear and shore power circuits.

Corinthian

A luxury motor yacht with multiple AC circuits supporting navigation electronics, HVAC, galley appliances, and entertainment systems.

Geist Sailing Yacht

Geist

A modern composite hull vessel with integrated battery management, inverter systems, and emergency AC backup circuits.

Each vessel underwent a detailed EICR and thermal imaging survey, ensuring every circuit and connection met stringent marine electrical standards.

Marine Vessel EICR and Thermal Imaging

Our structured EICR process for marine AC circuits is designed to confirm the safety, compliance, and ongoing reliability of the installation. The service includes:

1. Initial Assessment and System Review

  • Review shore power arrangements, onboard AC distribution boards, and earthing/bonding systems
  • Identify circuit types, protective devices, isolation points, and areas exposed to moisture, vibration, or mechanical damage

2. Visual Inspection

  • Shore power inlets and connectors
  • Main AC distribution panels and sub-boards
  • Circuit protective devices and RCD protection
  • Cable routing, supports, and containment
  • Glands, enclosures, and segregation
  • Socket outlets, fixed equipment, and appliances
  • Bonding and earthing conductors
  • We check for signs of deterioration, corrosion, overheating, loose connections, water ingress, and incorrect equipment selection.

3. Dead Testing of AC Circuits

  • Continuity of protective and bonding conductors
  • Insulation resistance of AC circuits
  • Verification of correct polarity

4. Live Testing of AC Circuits

  • Earth fault loop impedance
  • RCD disconnection times and trip currents
  • Verification of supply polarity and voltage
  • Functional operation of protective devices and isolators

5. Thermal Imaging

  • Main AC switchgear and distribution boards
  • RCD and MCB terminations
  • Shore power connection points
  • High-load circuits and fixed equipment supplies
  • Thermal imaging detects loose connections, overloads, imbalanced loading, and early-stage component failure, providing a non-intrusive safety check beyond standard inspections.

6. Recording and Reporting

  • Observations recorded with EICR coding principles
  • Clear prioritisation of defects and recommendations for remedial work

7. Certification

  • Full EICR report issued per vessel, including test results, thermal imaging, observations, and suggested improvements

All work was carried out on location in Barcelona, providing immediate on-site analysis and documentation.

Marine Vessel EICR and Thermal Imaging

Our structured EICR process for marine AC circuits is designed to confirm the safety, compliance, and ongoing reliability of the installation. The service includes:

1. System Design and Assessment

  • Confirm circuit types, protection methods, and AC/DC segregation

2. Equipment and Material Selection

  • Marine-rated distribution boards, protective devices, and accessories
  • Correctly sized cables, glands, and containment

3. Installation of Supply and Distribution Systems

  • Shore power inlets and main AC distribution boards
  • Local isolation and switching arrangements

4. Installation of AC Final Circuits

  • Socket outlet circuits and fixed equipment supplies
  • Secure, vibration-resistant cable supports
  • Correct segregation from DC and data cabling

5. Earthing and Bonding

  • Protective earthing for all AC circuits
  • Bonding to exposed conductive parts and metallic structures

6. Protection and Safety Systems

  • RCD protection for personnel safety
  • Correctly rated circuit breakers and protective devices
  • Clear labelling of all circuits, isolators, and equipment

7. Testing and Commissioning

  • Continuity and insulation resistance testing
  • Polarity verification
  • Earth fault loop impedance and RCD testing

8. Handover and Documentation

  • Full test results and installation documentation
  • Clear identification of circuits and equipment
  • Certification confirming safe, service-ready AC systems

All work was carried out on location in Barcelona, providing immediate on-site analysis and documentation.
