Appendix: Wire Specifications (Europe)
The requirements and specifications in this section reflect what is supported by Power Block 2000. When Power Block 2000 is connected to another ChargePoint product, such as a Power Link charging dispenser or battery, conductor characteristics may be further constrained by the connected product. Refer to the site design guide for each connected product and follow the most stringent requirements.
The following table summarizes the conductor requirements for each circuit.

IMPORTANT: Following are wire design specifications for Power Block 2000, including the maximum quantity and size that the wire terminals can accommodate. All sizing assumes a maximum ambient temperature of 50 °C (122 °F). Where the maximum wire size is listed, the actual wire quantity and size must be chosen based on site-specific wiring requirements and in accordance with the maximum allowed conduit filling rate per local code.

(*) The required number of 48 V DC wire pairs depends on the distance between Power Block 2000 and Power Link. See Ethernet Cable Type and Configuration section in the Site Design Guide. (**) The required Ethernet cable type depends upon the cable run length. See Ethernet Cable Type and Configuration section in the Site Design Guide. (***)Safety Hub is required only for certain models of Power Link. Refer to the installation guide of the Power Link model specific to your project to determine if Safety Hub twisted wire connection is required.
Plan for lugs and terminations using the following information:
-
Use copper lugs for copper conductors and aluminum lugs for aluminum conductors. The lugs must be nickel-, tin-, or silver-plated compression lugs (not mechanical lugs). Nickel-plated lugs installed with dielectric grease are recommended.
-
When using aluminum lugs, ChargePoint recommends applying an appropriate antioxidant compound to aluminum conductors when terminating into tin-, nickel-, or silver-plated lugs, where required by code or specified by the lug manufacturer.
