Electrical Safety in Ports, Marinas & Furniture: ITC Standards
ITC 42: Electrical Systems in Ports and Marinas
1. Purpose and Scope.
The requirements of this instruction apply to electrical installations in ports and marinas, specifically for supplying power to pleasure boats. Receivers used in these facilities must meet the requirements of applicable European Directives, as provided for in Article 6 of the Regulation for Low Voltage Electrotechnics.
2. General.
Electrical installations in ports and for pleasure boats must be designed and constructed with materials selected to ensure that no person is exposed to danger and that there is no risk of fire or explosion. Generally, the rated voltage of the facilities providing power to pleasure boats must not exceed 230V AC single-phase. Exceptionally, three-phase AC 400V may be used to feed yachts with high electricity consumption.
Protection against indirect contacts in non-conductive locations: Equipotential connections not linked to ground are not permitted.
4.2. Conduits/Pipes.
Cables with copper conductors, insulated and sheathed, must be installed in:
- Non-metallic conduits.
- Rigid, high-strength, non-metallic conduits.
- Galvanized conduits of medium or high resistance.
Acceptable cable types include:
- Mineral-insulated cables with a PVC protective cover.
- Cables with deck armor and thermoplastic or elastomeric material.
- Other wires and materials with superior mechanical protection.
4.3.3. Connecting to Pleasure Craft:
- A contact pin coupled with the protective conductor.
- A flexible cable, type H07RN-F, stably attached to the yacht through a connector.
- The cable length should not exceed 25 meters.
- The cable should have no connections or splices along its length.
ITC 43: Installation of General Receptors – Prescriptions
When installing capacitors and their connection with the receivers can be interrupted by switches, the capacitors must be fitted with ballast resistors or grounding.
Capacitors used for power factor improvement in induction motors must be installed so that when the electricity supply to the motor is cut, the capacitors are simultaneously disconnected.
ITC 44: Installation of Receptors – Lighting
This instruction applies to installations of receptors for lighting (illumination). A lighting receptor is defined as equipment or a device that uses electrical energy for indoor or outdoor lighting. This instruction does not include requirements for exterior lighting covered in ITC-BT-09 or emergency lighting in crowded public premises contained in ITC-BT-28.
ITC 49: Electrical Equipment in Furniture
The purpose of this Instruction is to identify the requirements for electrical installations within furniture and furniture elements. This includes:
- Furniture of all kinds, including office furniture, desks, speakers, panels, and similar fixed or mobile items.
- Furniture, mirrors, and bathroom items in rooms containing a bath or shower.
The receivers used in these facilities must meet the requirements of applicable European Directives, as provided for in Article 6 of the Regulation for Low Voltage Electrotechnics. Any furniture marketed with pre-installed electrical equipment (e.g., lights, switches, sockets) is considered a receiver.
