3.3 Electrical Equipment Ground Connections

Seakeeper to Vessel Ground Connection Instructions

1. Connect the Seakeeper foundation to vessel ground, as shown in Figure 25.
2. Install Ground Cable (10 AWG or 6 mm², Customer supplied) from the M6 brass ground stud on the Seakeeper rear brace to a suitable vessel ground.
   
   • EN/IEC 60204-1:2016, Clauses 6.3.3 and 8.2.3
   • ABYC E-11 July 2021, Clauses 11.5.2 and 11.17.
3. Ground connection should be made with a vessel bonding system, if available. However, the ground does not refer to a bonding system; for outboard boats, it generally refers to the negative terminal of the outboard engine. Per ABYC E-11 (2021), Clause 11.5.2.7.4: If the negative side of the DC system is to be connected to the ground, the connection shall be made only from the engine negative terminal, or its bus, to the DC grounding bus. This connection shall be used only to maintain the negative side of the circuit at ground potential and is not to carry current under normal operating conditions.
4. A proper ground connection is critically important for corrosion protection and helps ensure the unit’s ignition protection by preventing stray currents.
