What size wire can these accept?

The maximum diameter of the wire is OD3.5mm. It is recommended to use 14AWG soft silica gel wire for assembly

What are the ratings on these? i need something rated for at least 125vac/dc

These on their own would handle at least 15A at 125V just fine as long as you're not plugging in under power. Voltage rating is likely much higher hands-free, but probably 60VDC max for handheld use. It's just a simple hollow barrel though, so the ultimate rating would depend on the plug you use with it (spring force, materials etc). I'm using them for 12V at up to 8 amps without issue.
