Ep.63. Marine electrical systems: Pt. 1 Shore power and preventing electric shock drowning
Marine electrical systems Part 1 explains shore power and how an isolation transformer protects your boat galvanic corrosion and protects you from electric shock drowning risk. Pierre explains the way power is brought to the boat on BioTrek: the lithium batteries store the power so that we do not need to rely on variable power and variable quality of cabling on the dock. He explains electrical drift along the dock and why a galvanic insulator is not the solution to protect you and your boat. This video created while under quarantine in Canada and some view of the Otonabee river which is part of the Trent-Severn waterway system that connects Lake Ontario to Georgian Bay. Electric shock drowning: This happens a lot more than people think.
