What is the wire for 100A and 200A?

Question

is it ok for a 32mm square THHN wire

Answer 1

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.

Answer 2

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.
