Here we have 2 x 50A Red 3 Pin Style Anderson Style Sockets Plugs 50 Amp for Caravan and Camping (2pcs).

Non gender style meaning all can connect to each other, no specific male and female connection.

As pictured you will get 2 x 50amp connector and 6x pins which accept up to 6B&S, you can either crimp or solder the connections.

Keeping in mind 6mm automotive cable is suitable for 50amp so there is no need to use a thicker cable like 8B&S or 6B&S cable unless you cable length is extremely long or that you will be drawing more than 50amp and if that was the case then you would be best then using a larger Anderson style connector like a 100amp or 150amp style.

This 50amp style is by far the most common used on 4wd and caravan applications and is compatible with most common 50amp connectors.
