is it ok for a 32mm square THHN wire
wow,if this is the question,no offense,you need to hire a electrician also you can not use 90c rating unless lugs or breaker has a 90c rating.
For THHN wire (90*c/194*F), you would need: #3 Copper Wire Gauge Size 110 amp rating (doesn't account for voltage drop for distance) #2 for aluminum wire. #3/0 Copper Wire Gauge Size 225 amp rating (doesn't account for voltage drop for distance) #4/0 for aluminum wire. Note: A licensed electrician should be consulted in you area as local codes may differ.
