Standardised Bespoke EV Switchboards for Large EVC Rollout for UK Retail Parks
In a recent project, we have designed and manufactured a bespoke EV switchboard for our client to roll out across multiple retail park locations across the UK. Working closely with our customers ensures that they achieve the exact switchgear arrangement that their installations require.
For this project the customers requirement was to feed 5x 100kW EV fast chargers and provide protection against an open PEN conductor as the supply was derived from a shared transformer with PME earthing. The mains supply was to be rated at 1000A. The challenge for our design & quotations department was to standardise a design to suit these requirements as far as possible, suitable for a 20+ site EV charger roll out installation.
A bespoke board was designed at our Telford based operation and fitted with 2x 1000A, 3 pole, motor operated MCCBs, controlled by a matt:e O-PEN® monitor to provide open PEN protection. The monitor works in conjunction with an interlocking relay system which ensures the correct opening and closing sequence of the 1000A MCCBs. These MCCBs switch the supply to the distribution busbars which supplies 5x Proteus 200A, 4 pole, thermal / mag. MCCBs for the EVC supplies.
The design was detailed in technical drawings for our client to see and approve before the manufacturing commenced. Once approved, the design was processed through the various operations within the factory taking the materials from their raw formats to the designed and tested PRO2000 that is delivered to site.
There was also a width restriction at the installation location, which with the flexibility of the PRO2000 panel system and the in-house design expertise, we were able to easily accommodate.
To provide further protection, the panel was also fitted with Type 2 mains surge protection and thermostatically controlled, anti-condensation heaters. RCBOs fitted for local services and supply to a panel mounted 3 pin socket, all designed and assembled on-site before QC, testing and despatch.
The result, a once bespoke but now standardised for our customer, floor standing panel, with incoming cables top entry and EVC cables bottom exit.
