Hi
Can someone confirm that the output tethered lead is 5m,
The length of the commando cable?
Is this Ohme commando unit (£199) the same as the Ohme wall charger unit ( £500 ) apart from price and length of the input cable.
I am thinking of replacing a 6yr old tethered Chargemaster charger with the Ohme by removing the commando plug and wiring it in to the old junction box.
This seems like the cheapest way to get my self a new smart charger.
Any comments will be great.
Thanks

Whilst it may work in the sense that it will charge your car, the wiring regulations relating to ev charge points have been significantly updated. I cannot see that a 6 year old installation would fully comply with the latest regulations, by simply disconnecting your old charge point and wiring in a new ohme lead.

Without wishing to sound like a grump, I hope the earthing arrangements are correct for your installation.
If not under fault conditions the body of the car, may become live! o_O

Hi, This is the 6yr old insulation, waiting for a Ohme.
What would I need to make it safe or comply with current regulations.
Some have said since its already installed that its only complete new insulation that have to comply with the new regulations?

Thanks for your reply.
I am just waiting to move over to Octopus so you should get your £50 referral.
I had chargmaster ask for £505 to update my box to a new smart charger {no olev grant} , other company's are asking more.
Just because they are olev approved they are charging whatever they want.
A local electrician said he will fit the ohme £50 and certified.

Thanks for the referral,that's a good price.changing an accessory dosent require an update of regulation I find it strange that you can plug a granny charger in anyware but the problems with pen faults are still the same as they have always been with external power sheds etc.
Regards

Do you have a regulation, which lists an Ev charger as an accessory?

First of perhaps calling it a charger is not the right thing it's a power supply
That's out of the equipotential zone, same as a shed or a green house which under past regulation needed
Different earthing arrangement's on tncs/pme(rarely taken any notice of).
If it's not a new circuit or being altered
replacing a faulty part I think it ok.
After all theres no requirement to remove or upgrade anything installed in the past otherwise we would all be rewiring our house just needs a minor
Works certificate if you want to be squeaky clean
That's my take on it but I've been wrong before thanks for the interest

I’d have to also disagree with “power supply” :p

I completed the ev charging course this week so have a copy of the IET EV guidance note to hand.

I couldn’t find a definitive answer but I expect it will soon become quite common for electricians to be replacing charge points which could be 6-10 years old. Whilst 6-10 years old for an electrical install is not a particularly long time, the rate at which the regulations or equipment has been updated around ev charge points in the last few years could potentially mean a 10 year old install may not be as safe.

I’ll contact the ECA for a definite answer and report back (y)

Was this ever answered i.e. what are the differences between the various Ohme cables/charge points?

Thanks for the confirmation.

As previously stated, I'm thinking of using an Ohme cable as an EVSE by removing the type 2 plug and connecting to the mains. The Ohme manual states that some handshaking goes on between the original charge point and the Ohme cable - obviously not the case with the commando version.

I wonder if the handshaking is just to get the original CP to supply power by telling it that the Ohme is an EV. So will the cable Ohme still function without this handshaking?
