Consumer unit for EV

[davecooper]

I am about to get some quotes for replacing my ancient consumer unit. The chances are I will be considering an EV in the future but will not be getting a charging point fitted until then. Will this have any bearing on the type of consumer unit I have fitted? I imagine this is something I will have to mention to the engineer anyway. Thanks.

Just make sure your specify that any new CU must be capable of adding in an EV circuit later

This means a unit which must accept double pole RCBO’s

Many EV charge points are fitted by the supplier, and often the suppliers rules means the electrician doing the work can't use your existing consumer unit (CU) anyway.

The suppliers like Octopus have been doing such good deals with lower tariffs if they fit the charge point etc, it is really unfair competition for the independents.

I know I am slowly swapping type AC single pole switching uni-directional RCBOs, for type A double pole switching bidirectional RCBOs, but nothing forces you to change.

The new breed of EV can run bidirectional and move off-peak to peak times for the home to use, but this is rather new, and I don't know how many cars allow this?

But it does mean many RCDs will need changing for bidirectional.
