Extruder wiring upgrade - connectors

I’m adding connectors to the extruder to make it easier to work on away from the printer. I have installed them on the motor and thermostat wiring, but my connector wiring is much smaller than the wires for the heating element. I don’t want to risk using wiring or a connector that is too small for the power to the heating element.

For others that have done this, what gauge connector have you used for the heating element wiring?

Thank you,
