Caution: In a +40 °C ambient, 100 A circuit breakers can be used without a space provided the continuous current in
each device does not exceed 64 A. 100 A fuses, 150 A and 250 A circuit breakers do not require a space
adjacent to it.
At or above +65°C, the maximum size circuit breaker used shall be 125 A. The maximum size fuse used shall
be 70 A. Devices rated at 50 A or greater shall have an empty mounting position between it and any other
overcurrent protective device.
