Installation Requirements
SAFETY INFORMATION
Warning: The supplied BG SyncEV charger is manufactured
to be safe without risk provide they are installed correctly,
used, and maintained in accordance with the manufacturers
recommendations and installed by a competent electrical
installer in accordance with national and local regulations
and legislation applicable at the time of installation,
e.g. BS7671:2018 amendment 2.
The single phase EV charger should be connected to a
230V/240V nominal AC supply. The supply should run from
a dedicated 40A circuit breaker. We recommend the use of
a Type B curve circuit breakers. The EV charger features an
integral 30mA type-A RCD with 6mA DC leakage detection and
therefore an external RCD is not usually required:
1. For cables without earthed metallic covering installed in
walls or partitions at a depth of less than 50mm and also within
walls and partitions with metal parts, and not protected by
steel conduit or similar then RCD protection is required. This
can be achieved by using the BG IP65 EV protection enclosure
(CFEV1A) when mounted next to the existing consumer unit
as it includes a double pole 40A 30mA Type A RCD device
to protect the circuit. This can be used if the cable has no
mechanical protection where it passes through walls and
partitions and if the cable is buried within the ground before
reaching the EV charger. This will be in compliance with the
current BS7671 Amendment 2 Wiring Regulations.
2. If the cable is clipped directly to the surface of a wall and
does not pass through a wall or partition to the EV charger then
a standard B type 40A MCB may be installed into the Consumer
unit, however RCD protection may be required for other reasons
such as if it forms part of a TT system and the earth fault loop
impedance values cannot be met. This will be in compliance
with the current BS7671 Amendment 2 Wiring Regulations.
To conform with BS 7671, on occasions a double pole
MCB/RCD or other means of isolation may be required.
Important note: A DC Leakage fault in the vehicle may “blind”
a type “AC” RCD and render it ineective, never feed any EVSE
From an upstream Type “AC” RCD.
The EV Charger is pre-wired with 7.5M of cable, this should
not be extended with the use of adapters and only used with
the cable provided.
EARTHING REQUIREMENTS
The supplied EV charger features an on-board safety monitoring
system to detect low or high voltage supplies and potential
earth-neutral faults, this in accordance with regulation
722.411.4.1 (iv) of BS7671 2018 (Compliant on single phase
supplies only). If such a condition is encountered the charge
cycle is ended or prevented and the EV charger indicator goes
red and eectively becomes a double insulated (class II) device.
The vehicle becomes isolated from incoming supply and poses
no risk to touch. This feature removes the requirement for an
earth electrode where it may be ineective or introduce
further risk.
The EV charger may be connected directly to a TN-C-S (PME)
earthing system without any special arrangements. It remains
the responsibility of the installer to conduct a risk assessment of
the immediate area to a range of 10 meters (equipotential zone)
to ensure no other conductive metal xings pose risks (mixture
of TT/TN-S and TN-C-S), this is important where cable length
may enable charging inside or outside of a building/garage
where the vehicle is within touch distance. Where certain
conditions dictate an earth electrode must be used it shall be
independent from the distributors earth system with no direct
interconnection (the incoming supply SWA protective earth
should be isolated from the housing and/ or earth electrode).
The electrical installer shall install a suitable electrode complete
with termination housing and covers where appropriate,
warning labels should be visible and close to the unconnected
SWA protective earth, e.g. inside the charger.
The earth connection shall be made from the electrode to the
charger via copper conductor earth wire of an appropriate CSA
for the installation. The earth wire shall be installed in conduit
where there is a risk of mechanical damage or UV exposure.
Additional note: BG SyncEV recommend Earth electrode
impedance to be <100 ohms.
SURGE PROTECTION
Guidance on requirements for surge protection devices given In
BS7671: section 443.
The EV charger is protected against transient over voltages
(+/-2kV Line-Earth and +/-1kV Line-Line as a requirement of
EN 61000-6-1), a direct lightning strike carries a current of 30~
200kA the EV charger’s internal protection would provide little or
no protection in such an event, likewise nor would an SPD rated
less than 30kA. If life support equipment or business operations
could be aected by a lightning strike central SPD protection is
advised if it does not already exist.
The guidance on risk calculation in section 443.5 of BS7671 in
most cases is not possible due to unknown location of any SPD
already tted, length of cables to calculate LP etc, it is therefore
recommended a common sense approach is used on choice of
SPD (or if required).
ISOLATION AND SWITCHING FOR SAFETY
AND MAINTENANCE
To ensure the EV charger can be “turned o” to enhance
security and enable maintenance activities, a double pole
isolator (or DP RCD or RCBO) suitably rated must be
installed within the customer’s property. An isolator switch is
a mandatory requirement for “new builds”, but optional for
existing dwellings (at customer’s request), the switch should be
mounted between 500mm and 1500mm above nished oor
level to comply with regulations. The switch should be rated at
45 Amps. All installations must comply to BS7671: 2018.

Installation Requirements
INSTALLATION
The EV charger is suitable for installation inside and outside on
a solid wall or structure. The installer should consult with the
building owner to establish their preferred installation location.
This should take into consideration the length of charging cable
and risk of vehicle impact etc.
It is recommended the charger is installed at a height of
500mm-1500mm as per building regulations BS8300:2018.
If no suitable permanent structure is available, the EV charger
can be mounted to a stand. We recommend of the BG SyncEV
stand, EVASTAND12S (single) or EVASTAND12T (twin).
Ensure suitable xings are used depending on the mounting
surface. To avoid unnecessary dust inside the enclosure, it is
recommended to use the included xing hole template drill the
surface, before tting the enclosure.
Ensure installation wall has been checked for electric cabling or
pipework with a suitable detector.
NOTE: if any groundworks are required e.g. cable trenching or
earth electrode tment, it is advisable to check if underground
services could be present before commencement. Plans may
be available at: www.linesearchbeforeudig.co.uk (free to
domestic users).
The EV charger is suitable for bottom or rear cable entry, if
using rear cable entry ensure the blanking plug supplied is
tted to the open bottom cable entry hole. If using SWA cable
the included 25mm compression gland is NOT suitable, and an
alternative gland will be required. Do not drill alternative cable
entries into the charger housing, except marked cable entry
location for rear entry.
BG SyncEV recommends using EV-Ultra™ – Power & Data
Combined cable on installs that require a CT clamp to use the
chargers dynamic load management capabilities. Please see:
www.doncastercables.com/uploads/EV-Ultra_Datasheet.pdf
All of the cables that are to be connected into the supply
connector should have their insulation striped back 18-20mm.
Connectors supplied are suitable for cables of 4-6mm2and
suitable for solid and stranded cores.
LOAD BALANCING
If Load Balancing is required, we suggest of the BG SyncEV CT
clamp, EVA120CT1. This should be tted around the incoming
power to the main fuse and the correct max load (A) to be
entered during setup and installation steps.
FINAL ELECTRICAL TESTING
To meet the BS7671:2018 (18th edition) requirements for testing
of an electrical installation, the following tests and checks shall
be performed by a competent electrical installer before during
and after a BG SyncEV charger is installed:
• A visual inspection of the installation including the existing
electrical installation.
• Verication of the characteristics of the electrical supply at
the origin of the installation to conrm the supply is suitable
for the additional load.
• A test to conrm the continuity of the circuit protective
conductors.
• A test to conrm the integrity of the circuit insulation
resistance.
• A test to conrm the polarity of the installation is correct.
• Where applicable a test to conrm the earth electrode
resistance is within acceptable tolerances.
(or)
• An earth loop impedance test.
• A test of the mechanical operation of residual current
devices (RCD’s).
• A test to conrm the operation of residual current devices
(RCD’s)
is within stipulated time scales (at the rated current and at
ve times the rated current operating current).
• A test or calculated measurement of the prospective fault
current.
• A verication of the functional operation of the EV charger.
