EV charging point installation within buildings involves running heavy-duty electrical cables, mounting charger units on walls or posts, and connecting to the building's electrical distribution system. This work often takes place in occupied car parks where public vehicles and pedestrians are present. Electricians must manage the dual risks of electrical work and working in public access areas. This talk covers the safety requirements for EV charger installation inside buildings.
Key Hazards
Electric shock during cable connection and charger commissioning
Pedestrians and vehicles in occupied car parks entering the work zone
Cable damage from vehicles driving over unprotected trailing cables
Manual handling injuries from heavy charger units and cable drums
Control Measures
Isolate and lock off the relevant distribution board before starting any electrical work.
Establish a safe working zone in the car park using barriers, signage, and traffic cones.
Route cables in protected trunking or conduit to prevent vehicle damage and trip hazards.
Use mechanical aids to lift and position heavy charger units and cable drums safely.
Ensure all electrical installation work is carried out by qualified electricians to BS 7671.
Test and commission each charger fully before removing barriers and opening to public use.
Verify earthing, bonding, and RCD protection meet the design specification before energising.
Brief building occupants or site users on the temporary work zone and alternative parking.
Coordinate with the building management to schedule work during low-occupancy periods.
Remember
Isolate and lock off the distribution board before any electrical connection work begins
Establish a safe working zone with barriers and signage in occupied car park areas
Route all cables in protected trunking or conduit to prevent vehicle damage and trips
Test and commission every charger fully before removing barriers and opening to the public
All installation work must be carried out by qualified electricians to BS 7671 standards
