This is the AC electrical system as it was in 2010. The third distribution box was part of the system because it supplied the finished part of the boat which was separated from the battery room by the aft hold where we had to rip out the 1970s fit out and start again. Therefore we had only the supply lines from distribution box No.2, through the woking area and into the distribution box No.3, these could be protected. In 2011 we plan to rewire as drawn in the next page.
