Can you land 2 wires on a breaker?

Yes, you can land two wires on a single circuit breaker, but it depends on the type of breaker. Some breakers are designed to accept two wires (known as "double tap" or "dual tap" breakers), while others are not and may pose safety risks such as overheating. Always check the manufacturer's specifications and local electrical codes before attempting this, and when in doubt, consult a licensed electrician.
