In my area we have only one supply house in the county and they handle ITE loadcenters. A 200A 30-40 ct. copper buss indoor loadcenter runs $147.00. A 150A loadcenter runs $180.00. A 100A 30 ct. loadcenter runs $110.00. They tell me the demand pretty much regulates the prices. They also sell a 5/8" x 8' ground rod for $2.00 less than a 1/2" x 8'. They simply sell more 5/8" rods.
