Hi bomb thrower
Mr S is right. There is a standard key which you can get from any locksmith called an “NMB key” and this is usually sufficient, unless they have been rekeyed after installation.
In most buildings now, Ausgrid, (formerly Energy Australia) are updating the metres to wireless telemetry so they can dial in and read your usage remotely. They’ve done a few of ours already.
For your specific problem you need to clarify.
- Whether the circuit breakers (RCDs) themselves are getting on and may need replacing.
- Whether you can tap in and by pass the current circuit breakers that keep on tripping, and set up your own circuit breakers with your unit.
- Whether this is compliant with the BCA and other fire legislation.
- You may need to engage the services of an electrical engineer and an electrician to carry out the work, as well as a solicitor for setting up the exclusive use by-laws, as well as an EGM/AGM to approve them.
With all this hassle, it sounds like its easier giving the key to all the owners to have just in case power goes off.
Kind regards
