Maximum Demand / ENA / EV Help!

D4G
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 :)

    By the way, my January claim on the EVHS side has not been paid. WCS was fine but I suspect there is extreme pressure on the paper shufflers on the domestic end. I will be doing no more domestic EVSE installs, far too much hassle! 


    Seriously!

    I take it that you have been claiming before January with no issues? So you have had no grant money since then, how many have you fitted?

    Do you charge the customer and then refund them when the claim comes through or deduct it from the invoice straight away?
