Not good at all. I have used the Anderson Power Pole 30A for a while to all my equipment. This connector is so called unisex, it means you cant turnthem wrong if they are mounted correctly to their standard. I have done an info sheet about this. You can
find it here. It is done for the Swedish market but you can understad it by the pictures, or use Google translate.
Also many in the club found it good, now we can use the power system on the neighbour if out of power.
Lycka till.
