I finally got my inverter hooked up. It came down to only needing about 6 ft. of wire from battery to inverter. I had 2 50 amp breakers that came from a 12v winch that was on my work truck. I have a spade breaker someplace but cannot find now. I am not sure if needed or not as unit has on/off switch on it. I will install anyway when I find it. The sites that workshop gave me were very helpful. It fits perfect in area just under bathroom sink. When in use will leave door open for better air movement. Now I need to see if I can run cord under shower to TV which is next to shower.
