Fixing our Electrical System (part iii)

Fixing our Electrical System (part iii)

Time to work on the layout of the AC segment of the Electrical Control Panel.

Two major objectives are 1) Update the wiring so that they have the correct terminations, correct wire size, only one terminal connected to the switched side of the Circuit Breakers. 2) Reduce the risk of short or electrical shocks by covering the AC Circuit Breakers.

The Neutral and Ground AC wires are currently positioned on terminal blocks that will be removed. The new terminal blocks will be on the new Terminal Box Bread Board that will be secured to where the existing terminal blocks are located.

The three horizontal 5 port terminal blocks on the left of the panel are for the 110v AC connections.
The top block will be home for the Neutrals (note the jumper that joins all of the 5 terminals)
The lower block will be home for the Earths (similar jumper joining all of the 5 terminals)

The middle block, lower connections will connect to the Circuit Breakers on the control panel. 
The middle block, upper connections will connect to the appropriate devices (Outlets Port & Stbd, Water Heater, Inverter Charger, and the Air Conditioning System.)  

The three 110v Terminal blocks have insulating covers (the existing blocks do not).

Next I need to make sure I have enough Terminals, Wire, Heat Shrink, Labels etc. to start the project. I'm hoping that it will only take a couple of days to complete - but I'll make sure I have plenty of wiggle room as some of the wires will need to be changed from the blocks to their destination device. I would not be surprised to find that the '110v Outlets' have to be completely rewired and I will be installing GFCI's in each circuit (port and starboard). 

Still hoping we can go sailing before we start this - I say 'we' because it will save a lot of time if we can both get our heads around this project.

So, See you on the Water!
