Marine Electrics – defining power requirements

In the first post of this series, we saw that boat electrical and electronic equipment could be divided into two categories with incompatible power supply needs. We decided that this justified creating two independent electrical systems, one for equipment that needed a lot of power for a small number of short bursts each day, and [...]
