Civil and Mechanical Design

Use the guidance below to design the civil and mechanical aspects of the site.

The station can be installed attached to a wall, or on a concrete pedestal. The pedestal can be a newly poured pad or an existing concrete surface.

Component Dimensions and Weights

Each CT4000 charging station can be mounted on a pedestal or on a wall with a Cable Management Kit (CMK Cable Management Kit). The station is a vertical enclosure with the weights and dimensions shown as follows.

Charging Station Weights by Mounting Type
Station Configuration	Approximate Weight
Single port, wall	62 kg (136 lb)
Dual port, wall	68 kg (150 lb)
Single port, pedestal	71 kg (155 lb)
Dual port, pedestal	76 kg (168 lb)

Wall Mount Stations

For wall mounted stations, the wall must be smooth, stable, and plumb. The minimum height of the wall must be 1250 mm (49 in). Place wheel stops (a) 90 mm (3 ft) from the wall. The arc shows the usable reach of the two charging cable lengths available, 5.5 m (18 ft) (b) and 7 m (23 ft) (c).

Ensure that the wall supports the station. If mounting to a hollow wall, bridge at least two studs using a 41 mm (1 5/8 in) channel strut.

If not installed correctly, the ChargePoint charging station may pose a fall hazard, leading to death, personal injury, or property damage. Always use the provided Concrete Mounting Template shown preinstalled here, or a ChargePoint approved surface mounting solution, to install the ChargePoint charging station. Always install in accordance with applicable codes and standards using licensed professionals. Non approved installation methods are performed at the risk of the contractor and void the Limited One-Year Parts Exchange Warranty.

Pedestal Mount Stations

For newly poured pedestal mounted installations, the mounting surface must be smooth and cannot exceed a slope of 6 mm per 300 mm (0.25 in per ft). The concrete base must measure at least 600 mm (2 ft) on all sides. For installations in existing concrete, epoxy anchors can be used. Consult a civil engineer to ensure sufficient volume and strength of concrete.

There are three basic pedestal base designs:

In front of a curb (a) 900 mm (3 ft) x 2 (b)

Area: 0.42 m² (4.5 ft²)

Volume: 0.26 m³ (9 ft³)

Behind a curb (a) in a planter or berm 600 mm (2 ft) on each side

Area: 0.37 m² (4 ft²)

Volume: 0.23 m³ (8 ft³)

Use a retaining wall as needed to prevent dirt from accumulating on the pad.

Two stations back-to-back, centered between four spaces

900 mm (3 ft) on each side Area: 0.84 m² (9 ft²)

Volume: 0.51 m³ (18 ft³)

The pedestal base design can be configured in a variety of ways to serve different parking arrangements. Ensure a sufficient volume of concrete to provide anchoring for the charging station.

Place the station in a planter or berm between spaces with wheel stops 900 mm (3 ft) from the front of each stall (a).

Place the station against the curb between spaces with wheel stops 900 mm (3 ft) from the front of each stall. The base of the charging station can be flush with the parking spaces or at curb level.

Place two stations back-to-back centered on four spaces with wheel stops 900 mm (3 ft) from the front of each stall. The base of the charging station can be flush with the parking spaces or at curb level.

Place a dual holster station centered on the right space. The charging cables reach two vehicles. Place a wheel stop (a) 1220 mm (4 ft) from the center of the charging station. The arc shows the usable reach of the two charging cable lengths available: 5.5 m (18 ft) (b) and 7 m (23 ft) (c). The 7 m (23 ft) cord option is recommended for this configuration. The base of the charging station can be flush with the parking spaces or at curb level. Be sure to install EV Electric Vehicle Charging Station signs on both spaces.

Place a dual holster station centered between two parallel parking spaces, each 6 m (20 ft) long. Place the station (a) 450 mm (18 in) from the curb. A 7 m (23 ft) charging cable is recommended.
Place a single holster station for a single parallel parking space 6 m (20 ft) long. Place the station (a) 450 mm (18 in) from the curb, and 1.8 m (6 ft) from the front of the parking space (b).

Ensure any site slopes, walls, or fencing do not trap water around the charging station installation site. The system is only built to withstand water to the height of the conduit stub-up.

Exposing the ChargePoint® charging station to water above the height of the conduit stub-up could create an electrocution, shock, or fire hazard. Cut power to the charging station if it has been exposed to standing water and contact ChargePoint before the charging station is powered on.

For pedestal installations, the conduit stub-up must be a minimum of 230 mm (9 in) from any obstructions to the rear. This includes other charging stations. Check applicable codes for any additional clearance requirements.

Electrical Specifications

For electrical specifications, refer to the CT4000 Installation guide.

CT4000 can run on 208/240 V circuits from 20 A to 40 A and will deliver a maximum of 30 A to a vehicle. Since CT4000 supports lugs up to 16 mm2 (6 AWG

American Wire Gauge), we recommend running 16 mm2 (6 AWG

American Wire Gauge) wire for potential upgrade to higher power chargers in the future.

Accessibility

To meet the accessibility requirements, the CT4000 charging cables are no more than 1220 mm (48 in) above ground and no more than 254 mm (10 in) away.

This complies with American Disability Act (ADA) requirements if the station is installed at grade. If your installation must comply with ADA standards, or the disability access regulations for other regions, consider this when designing the height of the pad or when planning a wall-mounted installation.

This complies with Europe disability requirements, if the station is installed at grade. If your installation must comply with disability access regulations, consider this when designing the height of the pad or when planning a wall-mounted installation.
