Quick question about Anderson style connectors

[Dadnatron]

Can a 1ga wire connector be mated to a 4ga connector? The 4ga is 50amp.

I've only used the 4ga size, and was going to hook up a connector from my truck batter to the back of the truck for a direct dump trailer feed. I thought I would also use it to power my 12v fuel transfer pump on the tank for the farm. However, I realized the tank has a 4ga connector and I had planned on using 1ga from the battery to the back of the truck.

Basically, are there different physical sizes of connectors for different gauge wires?

You can get different sizes of the contacts.
But you need a bigger shell probably.

Thanks for the link. I called that company and they said that in all likelihood, I need a different shell. And it will work. Just pop out the connectors and put them in a new shell.

Thanks

As you can see in the link, the SB350 series housing will take connectors ranging from 1/0g to 4/0g. Those are gigantic! Good for up to 350 amps! It sounds like you may currently have the SB175 or PP180 series housings and terminals, as these will take terminals from 1/0 through 6g.

You just need to get the correct size terminal for your wire. Anderson/Powerwerx also sell reducing bushings if needed to fit smaller wire in the larger terminals.
