I believe that it is a 50 amp breaker with 8 wire at the cabin panel. But if I were to go that route why not just tap off the positive post under the dash panel? I could go from the positive post right to the switch panel.
This is where I get start to get confused.
and when confusion sets in, I tend error on the side of caution.
To measure the length of the circuit for the voltage drop don't I need to factor in the run from the batteries to the cabin breaker panel as well as the distance to the helm and back to the batteries to correctly size the wire for the voltage drop? Or can I just measure the voltage at the panel with a digital multimeter to ensure I have adequate voltage?
Currently everything is connected to the helm breaker,
Fore and aft ceiling lights
2 windshield wipers and I am planning to add one for the center window
Raw water wash down pump
Trim Tab Controls
12 volt receptacle
Vhf radio (max draw 6 amps)
Autopilot (according to Raymarine 15 amps)
9" display 2 amps
7" display 1 amp
Radar 2 amps
Have not hooked up a stereo as of yet
All of this is why I figured on running another circuit. I would rather be safe then sorry,
Your thoughts on this David or anyone else reading this?
