2.2 Service Wiring

2.2.1 Ground Connection
Always connect the Neutral at the service to Earth Ground.
If ground is not provided by the electrical service, you must
install a grounding stake nearby. The grounding stake must
be connected to the ground bar in the main breaker panel,
and Neutral connected to Ground at that point.
2.2.2 200V / 208V / 240V Single-Phase
WARNING! If the DC Wallbox is a single-
phase device, do not connect all three
phases of a three-phase feed.
CAUTION The two phases used must each
measure 120V to Neutral. Earth ground must
be connected to Neutral at only one point,
usually at the breaker panel.
2.2.3 277V Single-Phase
CAUTION The 277V is feed from the
Y-connection power grid. The DC Wallbox can
connect to L1, L2 or L3, and Neutral. Earth
ground must be connected to Neutral at only
one point, usually at the breaker panel.
