You look at your cable table. 29A means you need a (approx AWG 10) copper cable for the thermal rating. ( \frac{19
When in doubt, go one size larger. The cost of copper today is trivial compared to the cost of a trench re-dig, a fire investigation, or a day of factory downtime. a fire investigation
