IBB- Inland Boating Electrical Awareness

Brand new Inland Boat Building Electrical awareness course

Course information

The aim of the IBB is to give you a basic understanding of both AC and DC electrical systems.  So that with time and completing other training courses the Inland Boatbuilding industry takes a more professional approach to electrical system design and installation. 

Regulations and standards that we must use every day. 

Several people who undertake electrical design and installations have minimal knowledge of what standards they should be following.  We want to boost their knowledge of both the AC and DC ISO’s and current Boat Safety Scheme requirements. We will include a handout on H&S at work as part of the course. 

Why it is so important to select the correct cable. 

  • The advantages/ disadvantages of which voltage to use either, 12 or 24-volts
  • Volt-drop- In an owner’s boat manual, it is rare to find volt-drop calculations or even appropriate documentation.  

Best practice

  • Cable installation
  • Cable termination
  • The correct ways to interconnect batteries and the use of bus bars.  

Correct equipment selection

  • Looking at what types of bus bar to use, current rating etc. 
  • Current rating of battery master switches and which type to use. 

Correct AC installation and design

  • AC system design
  • Understanding the correct way to install AC protection in new boats today
  • Where do you install an RCD?  
  • What type and which rating of MCB’s. 

Testing and documentation

At the end of each ISO 10133 and 13297 there are sections that cover circuit and system testing. 

Most if not all boat yards do not test their installations or produce any form of documentation to record the results.
