Isolation for EV charger

[jpadie]

Dear all

Is an isolation switch a regs requirement for maintenance on an EV charger?  

 

The charger is supplied from a secondary cu that has dual pole isolation. The secondary cu serves a garden room.  The charger is attached to its wall.  

 

The main supply has the usual isolation switch in the CU and an isolation switch after the meter and before the CU.  The secondary CU is supplied from the main CU via an MCB.  

 

This is a self install on a circuit that has already been signed off.  

 

Thanks in advance.
