I purchased the 4 pole 63 amp blue 4P63A. Construction quality appears good but will find out more once I install it. Lots of YouTube videos of similar products. I used a VOM continuity mode to map out connections including the control/sense block.For the numbers left and right they are exactly as one would expect. When arrow is left then left 135N is connected to left 246N respectively, and when arrow is right, ditto. There are no cross-connections on the 246n left and right so if the load for arrow left and arrow right are to be the same load then you would need to cross-connect 246n on the left to 246n on the right.The only thing that I'm not sure about is the green control/sense block, whatever it is. The best that I could do is to map out the pins/terminals. I'll call then ABCD. See photo. Also the pin mapping below was put into a pin-matrix, see photo.If anyone can help me to understand what these 4 pins on the green block are for then please let me know somehow! It seems like I can just skip them based on the YouTube videos of similar products.Just FYI, Ground isn't mentioned anywhere afaik. I wanted the 4-pole so that I can at least isolate the two 110 volt wires (for 220 volt switchover), the neutral, and the ground. Just made sense to me but I AM NOT AN ELECTRICIAN and I have never quite grasp how to best ground things so that they are not grounded in two places -- that seems to be a bad thing to do.Here is the mapping of the 4 pins on the green terminal. It doesn't make sense to me. I don't think that I need to use them at all. I'll update this review after I install it.ON MANUAL:When direction (arrow pointing downward) is pointing to the LEFT:Control:A to nothingB to BOTH N and N on LEFTC to nothingD to N on the TOP-RIGHT ONLYWhen direction arrow pointing to right:Control:A to nothingB to nothingC to BOTH 1 AND 2 on RIGHTD to BOTH N and N on RIGHTON AUTO:When direction (arrow pointing downward) is pointing to the LEFT:Control:A to nothingB to BOTH N and N on LEFTC to nothingD to N on the TOP-RIGHT ONLYWhen direction arrow pointing to right:Control:A to nothingB to N on the TOP-LEFT ONLYC to BOTH 1 AND 2 on RIGHTD to BOTH N and N on RIGHT

4.0 out of 5 stars Works as expected, operation is a bit loud.
Reviewed in the United States on March 20, 2024
Install was not that difficult. Could have been much easier if the instructions were better. To say they are lacking is an understatement. Used switch to provide inverter power to general recepticals when switching from shore/generator power to inverter power.

5.0 out of 5 stars It works like a charm
Reviewed in the United States on March 18, 2024
I installed it in my Scamp trailer to switch between inverter or external power with no function issue. It is also a good size to install in a compact area.

5.0 out of 5 stars what the green terminals are used for
Reviewed in the United States on February 16, 2024
The green terminals at the bottom of the unit are used if you want to connect external indicator lights which tell you if the main or backup circuit is energized.
