Thanks for the reply do they sell a consumer unit with earthing arrangement? As i think i will opt for that also? Many thanks for the helpThey will probably fit an additional consumer unit if no space. TBH that is preferable anyhow - keeps prolonged high current out of an existing consumer unit.
Gen 3 TWC already has the DC protection built in so no need for B type RCD.
Earth protection is dependent on your current earthing arrangement. Electrician will tell you what additional protection is needed if any.
hi steve, any chance of a picture of your install or the o-pen device you have fitted? I wonder if i can get a open device with earth protection as i dont have earth rods as its also located in a garage. @scdoubleuGen3 still needs supplemental earthing if the supply is PME, usually in the form of a rod. Had a Gen3 fitted in the (detached) garage last week, along with O-PEN protection in a separate box adjacent to the garage sub-panel. Fortunately, I had an earth rod fitted already as part of the PowerWall installation last month.
