I have an earth grounding pin outside my house and an earth wire running from it to my distribution board, however the wire is not connected to the earth rail (ground rail?) In the DB.
(The house is already earthed but a new earth pin was installed as part of a recent upgrade but never connected up for some reason)
I'd like to connect it. I'm thinking I can simply connect the earth wire to the existing earth rail and be done with it.
Does that sound ok?, or does there need to be a circuit breaker between the earth wire and the earth rail in the DB?
This is in New Zealand, btw.
