What breaker do you use for 10-2 wire?

Answer 1

Assuming a 120V circuit then a 30A Single Pole. For a 240V circuit an 30A two pole. Of course anything smaller that a 30A is acceptable. 30A is the maximum allowed.

Answer 2

For 10-2 wire, you would typically use a 30-amp breaker. This size breaker is commonly used for 10-gauge wire in residential electrical installations. Make sure to check your local electrical codes and the manufacturer's recommendations for the specific application.

Answer 3

30 amp duplex breaker...and you should use 10/3 wire, not 10/2. 10/2 is for water heaters.
