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 SyncEV BG
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.
