Hello all,
This evenings issue relates to an EV charger install.
The supply cut out is labelled 60/80 amp so I called the DNO and asked if this could be uprated to 100 amp.
They have sent me the ENA EV application form which asks for the Maximum Demand including the new equipment.
The problem I have is the existing circuits are:
32A - 7.2 kW shower
40A - 8.2 kW shower
32A - Ring main
32A - 7.9 kw cooker
6A - lighting
6A - lighting
6A - security
Additional 32A for EV charger
So even with diversity I'm way over 100A, obviously in reality the diversity calculations are not appropriate as the client has never blown the cut out.
The smaller shower is not currently in use although they want to replace it for another one, I have told them this may not be possible.
The EV charger will have load management but I still need to put a figure on the ENA form....
Help appriciated :)
