isolator or isolation transformer is referenced in ABYC E-8.20 and ABYC E-8.11.

Generator sets installed in commercial vessels are governed by U.S. Coast Guard Regulations, Title 46, the American Bureau of Shipping, and Lloyd’s Register of Shipping. Grounding of equipment is covered in ABS

35.9.6and Lloyd’s Part 6, Chapter 2-1, Section 1.3. The types of permissible neutral grounding of generating equipment are referenced in ABS 35.125 and 35.95.1 and in Lloyd’s Part 6, Chapter 2-1, Section 14.4. Ground fault protection information can be found in Lloyd’s Part 6, Chapter 2-1, Section 14.5 and Part 6, Chapter 2-2, Section 13.6.

Battery

Batteries and their installation must conform to U.S.C.G. Regulations 183.420 (a) through (g). Generator sets should use batteries separate from the propulsion engines whenever possible. Both the generator set and the propulsion engines’starting/charging systems must have a common negative (--) ground.

U.S.C.G Regulation 183.415, Grounding, requires a common conductor to be connected to each grounded cranking motor circuit. This conductor should be sized to match the larger of the engines’two battery cables. (Cable sizes for generator set battery connections are given in Figure 6-20.) This requirement prevents the starting motor current from using alternative electrical paths should the cranking motor ground circuit be restricted or open due to oxidation or loose hardware. These alternative electrical paths include metallic fuel lines which can pose a fire hazard. See Figure 6-21 for battery connections to generator set.

Wiring

All wiring must be stranded copper. Wire gauges and insulation, conductor temperature ratings, sheath stripping, conductor support and protection, conductor terminals and splices, and overcurrent protection (circuit breakers, fuses) must conform to U.S.C.G. Regulations 183.425 through 183.460. Use rubber grommets and cable ties, as necessary, to protect and secure wiring from sharp objects, exhaust system, and any moving parts.
