Which risk increases when repeatedly resetting a tripped circuit breaker?

💡 Explanation

Repeatedly resetting a tripped breaker raises the risk of contact welding because the inrush current upon closure pits the contacts and overheats them; therefore, increased weld probability, rather than grid effects may occur at individual residential circuits.
