I cut the old connector out and put but connectors on the new wire. My connector had larger wire going from the connector to the power adapter.
The fridge uses slightly less than 4 amps on 12 volts. That is what the original inverter is rated at.
The wiring in theory should have been able to handle 4 amps.
The initial surge is the problem. The turn on surge drops the voltage down below the minimum input voltage and the inverter shuts down.
I changed to 10 gauge wire and ran to the main ships power breaker at the back of the boat. Everything was on that side and made life a lot easier to run the wires.
If it only draws 4 amps, I am surprised the #16 didn't work that short of a distance,
doing the math (2x10.4x4x20') then divided by .36 = 4622 cm
14 awg is 4107....
12 awg is 6530.....
so yes, 16 would work if the length was about 11'..... I think 20' is a little more reasonable,could be 15' which would be #14...
i would;d say #10 is safe, #12 is probably enough...
interesting stuff here.... i wonder what the exact amp draw is, that would effect it a little. i use 10.4 as the K (constant) some use 11....
sorry, this is the electrician in me
btw, thanks for the site Gary, great info there!
