Help please. Putting in a 50 amp service at home.

Whoever said they had #10 wire with a dual 50 amp breaker, you need to replace it with the dual 30 amp breaker. You risk lighting up the #10 wire with 50 amps. Everything will work the same, except if you draw more than 30 amps you trip the breaker vs burning up #10 wire and maybe your home. Do it, switch to the lower rated dual breaker asp.
