Section 3: Installation

3.1 Building Survey

• Available voltage, current and frequency
• VersiCharge electric vehicle charging stations can draw up to 30
A at 240 VAC, 60 Hz (7.2kW of power). The complete electrical
structure of the building must be adequately sized to handle the
entire building energy load, under peak conditions, as well as
the charging station load under operation.
• Checking for adequate power includes all the connections from
the utility through the entire circuit structure to the branch circuit
position and connected wiring.
• Utility connection and transformer capacity - check with utility
service provider to ensure enough power is available for the
building and the VersiCharge under full loading.
• Available breaker positions and amperage
• Verify the panel has an open position for a two pole breaker.
• Verify that the 30 A draw from the VersiCharge will not exceed
the loading for the Main Breaker of the structure.
• Breaker selection
• A 2-pole, 40 A dedicated branch breaker is required for both
cord-and-plug installation and hard wired installations.
• Siemens Part numbers: Q240 (plug-in type), B240 (bolt-on
