Please could I have some assistance in completing the ENA application forms we now have load management equipment for each site, but I am not sure how to correctly complete the values .
From my understanding if the EV charging is under 30% of the supply capacity we can install and notify, if it is above 30% then we need to submit an application.
We submitted an ENA application where the supply capacity was 277KVA with a new maximum demand with all the chargers and the sites existing maximum demand loadings equaling 234kva less than the sites supply capacity.
The ENA application asks us to advise what value in amps what the sites demand would be restricted to, and as our current application is less than the supply capacity, I am unsure what value we could input as we only need to submit the application if greater than the 30%
Obviously we want to maximise the charging capacity for this site. The site has a 277kva 400A supply of which the sites maximum demand is 97A leaving 300A spare capacity. Ev Charging is 242A but can be managed to reduce it to the desired value??
