What's the score with using a 32A commando socket with the Ohme commando plug regarding earthing.

New 18th edition wiring regulations expect a dedicated earth rod for new charging installations, not connected to the earth of the house.

Clearly you need to wire up a 32A commando socket with an earth as other devices can be plugged into this socket. How is the ohme charging connector get away this not having an earth rod connected, is it classed as a portable charging device rather than fixed? Is that how they are getting away with it?

I've read it has its own built in RCD to comply with the DC tripping regulations so that bit is covered. Can't find much information online about the commando plug and it's regulations.

This came in the box.

The argument is probably that a 32A commando isn't necessarily a dedicated EV supply - could be for a welder. A portable EVSE like the OHME is probably outside the scope of the wiring regs.
My understanding is that the regs only apply to fixed wiring. Portable equipment is covered by specific standards for that equipment.
Even if a CEE outlet is being provided primarily to supply a portable car charger I doubt the regulations for fixed car chargers could be legally enforced, though some electricians might attempt to.

Hi Dean and all people on this thread.

I am head of strategic partnerships at Ohme and would be pleased to hear more on your feedback and tell more about Ohme if you have any interest.

We also now have an OLEV approved smart wall charger for a retail price of £480 incl. VAT.

Yes, there is a sim card inside all our cables and wall chargers.

Our wall chargers have same functionality as the Ohme cables, the wall charger just comes with a bit longer lead in one end to wire into a junction box/into a wall + holder for gun and cable.

The Ohme cable is a great way to upgrade any dumb chargesockets to be smart.

It also works well with GO tariff or other fixed time period tariffs.

My email is [email protected] and my phone number is +44 7425224146 and it would be great to hear from you.

Best regards,
Stefan

Hi Stefan,

Just wondering if the Wall Charger option is something offered to Octopus customers at all as the other 3 options seem to be there and this would be a nice way to get the OLEV grant applied as well would it not?

Does anyone know of an adapter that can plug into a Commando socket on one side and provide a socket for a normal Type 2 EV cable on the other side? Or is there a good reason why that isn’t possible?

I ask because a holiday cottage we will be staying at has a Commando socket...
I modified my portable EVSE aka granny charger so that the primary plug was a CEE Commando 16A plug. For use at holiday cottages, campsites, farmers barns etc. I then made up an adaptor , CEE socket to 13A plug.

Lots of good reasons to make the primary plug a CEE unit.

You can find a write up on the forum if you search through my initiated posts.

This is an old post but for the record you can buy a commando plug to 13 amp socket adaptor for less that a fiver which will enable you to plug your granny lead in. I carry one because golf clubs often use a commando for charging the buggies so in an emergency I can use one.
