I'm seriously considering buying a Vauxhall Ampera, and I'm doing some planning for home charging. My question concerns earthing requirements for a home charging unit. I see references to people needing an earth spike installing as part of the charging unit installation, with possible digging up of drives, etc. Can anyone explain when a new earth connection is required? I know that if the current house earth is to a gas or water pipe then this is NOT deemed adequate (read this in the Pod Point installation guide I believe). In my house (20 yrs old), I have a thick green and yellow earth wire coming out of the consumer unit along with the two heavy supply cables from my meter, which connects in someway into the supplier side of the meter - it disappears into a plastic housing from which the two thick supply cables enter the meter. I wonder if this means I would have adequate earthing already. What experiences have people had with the earthing arrangements?

I see you have posted this twice on the forum. It is never a good idea to post something twice. Just pick the most appropriate section and post there... people will see it.

The mods may want to remove one of the posts.

Ah - sorry Paul, thought it might be OK as it was on different boards, point taken..

No worries at all. It is the same board... just different sections :)

This is probably the case for most forums... having two posts the same just splits the readership and the replies and makes it difficult to follow the thread.

The earth requirements are complex...

In a nut shell, assuming the charge station is attached to your property, an earth spike probably won't be required.

This shouldn't be confused with earth bonding which needs to be in line with BS7671 wiring regulations when any additions are made to the electrical installation.

If you take photos of the earth connections to your water and gas, plus photos of your consumer unit, import meter and supply cut out fuse I'll be able to tell you if it is.

Hope this helps!
