Maximum Demand / ENA / EV Help!

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 :)

    I think that the next big shock will be the level of tax for electric vehicles once they become a significant proportion of vehicles. Interesting times ahead!


    Well they did it in the late 80's early 90's when petrol was £1.75 a gallon but diesel was only £1.50 a gallon. As the revenue fell due to less petrol being sold, the price of diesel increased to be where we ae today with diesel being dearer than petrol. The same happened with LPG and as David indicated, the loss of fuel revenue will no doubt come from the alternative source/use of energy...........Unless St Greta can make up the lost revenue.................
