3.1.2 Grounding Requirements
The charger must be connected to a grounded, metal, and permanent wiring system. An equipment-
grounding conductor must be run with circuit conductors and connected to an equipment-grounding
terminal or lead on the charger.
A grounding conductor that complies with applicable codes must be grounded to earth at the service
equipment or, when supplied by a separate system, at the supply transformer.
Neutral is not used to power the charger but must be properly connected to ground, at the panel transformer,
to provide necessary voltage reference relative to ground.
3.2 Preparing for Installation
3.2.1 Location
Install the charger on a flat and vertical surface capable of supporting its weight (e.g., a finished wall or
pedestal). The maximum weight of a MaxiCharger AC residential 10 kW/12 kW is approximately 14.8 lbs.
(6.7 kg).
Install the charger in a location that allows the charging cable to remain within its bending tolerance.
Position the charger in a location where it is not vulnerable to being damaged.
3.2.2 Positioning
1. Determine the desired charging amperage and whether the desired circuit rating requires a hardwired
circuit. Choose based on the electrical capacity in the panel, the desired speed of charging, and whether
the user prefers a NEMA plug-in or hardwired installation.
