C10 Verification By Basic Visual Inspection C10.1 General This Paragraph (C10) details requirements for basic visual inspection of an electrical installation to confirm that the installation remains in good repair and does not exhibit indications of misuse or damage. This inspection doe not include any electrical testing. Which is covered in Paragraph C11. C10.2 Inspection Requirements Inspection of electrical equipment and conductors shall include the applicable checks listed below plus any additional visual checks required to verify that the installation is in safe condition:

Cables Show no undue evidence of insulation or sheath deterioration and have appropriate mechanical protection for the environment in which they are installed.

Electrical fittings in explosive gas areas have the correct rating and are appropriate for the zone (see Clause 2.12)

Socket-outlets exhibit no mechanical damage and there is no evidence of overheating

Light Fixtures exhibit no evidence of mechanical damage or evidence of undue overheating or arcing

Lamps do not exceed the wattage ratings of the fittings in which they are installed

LV a.c. systems and ELV d.c. systems are separated (as best possible).

Electrical Equipment is adequately supported.

Electrical equipment and fixed-wired appliances forming part of the electrical installation are not damaged.

Circuit and supply source electrical protection complies with clause 5.3 and 5.4:
5.3; D.C. Electrical System
5.4; A.C. Electrical System

If Installed, a digital network power distribution, control and monitoring system meets the requirements of clause 2.18

d.c. and a.c. electrical systems and systems of different voltages shall have the distribution from the different systems from either seperate distribution boards, or from a common distribution board with partition to seperate the sections of different systems from each other.

Switchboard and electrical equipment have no conductor insulation deterioration.

RCD's, RCBO's, MCB's, fuses and switches show no evidence of mechanical damage

Semi-enclosed rewardable fuses, where fitted, have not deteriorated due to arcing and have no exposed live parts when the fuse carrier is fitted into the fuse base.
NOTE: Semi-enclosed rewireable fuses are not permitted in new installations or in alterations to an existing installation.

There is adequate insulation and distance between live conductors and between live conductors and earth; where the conductors are bare, refer to CL 2.7.7.
Cl2.7.7 Busbars
Busbars and their connections shall be made of copper and shall be designed to withstand mechanical stresses due to short-circuit. The maximum temperature rise shall be 45°C. Bare busbars shall comply with the minimum clearances and creepage distances given in Table 4. Page 24 AS/NZS 3004.2 (2014)

Non-standard wiring identification label (if applicable)

Switches and protective devices are clearly labelled showing the circuit type they control or protect.

Instruments required by CL2.5.6 and are fitted
CL 2.5.6;Measuring instruments
CL; Voltmeter

For boats with an IT AC system, a continuously operating earth fault or insulation monitoring and alarm system installed.

When an inverter is installed, the hazard warning label required by CL 2.6.3 is fitted to or beside the a.c. switchboard.

Neutral bars are supported on insulated fittings

Where there are seperate earth and neutral bars, earthing conductors are connected to the earth bar and neutral conductors are connected to the neutral bar.

The main earth conductor from the boat's earth is correctly connected and labelled at the main switchboard.

The switchboard is constructed and installed in such a manner that, in the event of fire, the spread of fire will be kept to a minimum.

Residual current devices (RCD's,RCBO's) installed for personnel protection have a residual operating current of 30mA or less.

Conductors are securely held in terminals of fittings and are no subject to tension at the terminations.

The main earthing and equipotential bonding conductor terminations are accessible.

Earthing connections are mechanically sound and fixed by a secure system.

Earthing and equipotential bonding connections are protected against mechanical damage, corrosion and any vibration likely to occur.

Conductors of cables are correctly identified and are connected to the correct terminals of fittings.

The portions of the boat earth inside the boat show no evidence of corrosion, damage or poor connection of the earthing conductor(s).

Appliances are correctly positioned and are suitable for the environment they are located in.

Covers of fixed wired appliances are not broken or missing, giving access to live parts or basic insulation.
NOTE: Connections to electrical equipment need to be enclosed and require the use of a tool to gain access.

Electrical appliances are correctly mounted and protected against mechanical damage.

Electrical fittings in damp areas have correct IP rating and are appropriate for the zone.

Exposed metal liable to become alive is connected to earth.

All batteries are secured against movements and inclinations occurring during boat movement.

Batteries shall be covered for protection of battery and battery terminals from loose and falling objects.

Batteries shall not be installed directly above or below a fuel tank or fuel filter, and any other metallic component of the fuel system within 300mm above battery top, as installed, shall be electrically insulated.

Battery overcorrect protection complies with clause 5.3.1
CL5.3.1; Protective Devices.

Battery ventilation complies with Clause 2.9.2
CL2.9.2; Ventilation

Lithium Battery installations comply with the following:
AS/NZS 3004.2 (2014) CL 2.9.3

Confirm the boats shore power connection (s) comply with Clause 3.5.2
CL 3.5.2; Boat Connections.

Shore Power available indication is provided by the supply changeover switch.

Shore Power Reverse Polarity protection is provided in accordance with clause
CL3.5.3.2; Protection against reverse polarity in the supply lead.
