What surge level should a primary distribution box use
3 of GB 50057-2012: A surge protector of Class I test should be installed at the main distribution box where the power supply is introduced. The voltage protection level value of the surge protector should be ≤2. Connecting cables that are too long often lead to problems. Depending on the application and protection. When installing a surge suppressor, it is important to mount it as close to the electrical equipment as possible in order to keep the wiring (lead length) between the electrical equipment and the suppressor as short as possible. A Type 1 SPD meets the criteria if it can handle an impulse current.

Does a primary distribution box need a power meter
Many large industrial/commercial customers request primary voltage for their service -- utilizing their own transformers to step-down the voltage for their requirements. A feeder usually begins with a feeder breaker at the distribution substation. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV. Since primary metering installs its equipment on the primary, the metering equipment is rated for this higher voltage. Primary metering installations are typically. A meter box is an electrical enclosure designed to house the electricity meter and related service connections. It acts as the formal interface between the utility power supply and the consumer's internal electrical system.
