Connecting Electrical Power
Step 1
Once the Boost Charger has been bolted to the concrete pad and torqued, open the front access
door of the charger using the provided keys.
Step 2
Prepare the service wiring by making sure it has been pulled through the conduit to the installation
pad.
Note:
The terminal block on the Boost Charger accepts 2 AWG wires only. If using a larger gauge
wire to accommodate a long run, reduce the wire size at the disconnect.
Step 3
For 208 V 3-phase, use Phases A, Phase B, Phase C, Ground, and Neutral as shown in the photo
below. For 240 V split phase, use Phases A and B plus Neutral as identified in the photo below.
Step 4
Verify the length of the wire needed to connect to the Boost Charger terminal block as shown in the
photo below. Trim any excess wire.
Note:
Make sure the wire can reach the terminal block and ground location first, then trim any
excess.
Step 5
Strip each wire 1” (25mm).
Step 6
Connect the wires to the appropriate phase, neutral, and ground based on the supply voltage. To
connect the wires, loosen up the bolts on the terminal blocks and insert the appropriate wire into its
equivalent terminal.
Step 7
Torque the bolts to 50 in-lbs.
Step 8
Confirm each wire is held securely inside the connector by trying to pull the wire downward.
