Cathodic protection systems
If your business is planning to install a registrable cathodic protection system you must give at least 60 days notice to the Electrical Safety Office before installation commences.
Regulations are in place to ensure cathodic protection systems are installed safely and maintained appropriately.
You must arrange to have all cathodic systems tested, even those that do not need to be registered.
This guide explains how your business can legally operate a cathodic protection system.
Testing your cathodic protection system
Systems that require registration must be tested within 90 days of lodging an application through Cathodic Protection Registrations Online. All systems must comply with Part 13, Division 5, System requirements as outlined in the Electrical Safety Regulation 2013.
Tests must include:
- interference tests on all foreign structures for the system
- maximum voltage checks on water based or marine environment systems
- checks on maximum current discharged into a marine environment or ground.
Testing should be done on the maximum operating current values stated in your application to the Electrical Safety Office.
It is your responsibility to:
- notify owners of all nearby foreign structures
- arrange testing
- provide all the facilities
- pay all costs associated with testing.
For more information on testing cathodic protection systems before operation, read the Electrical Safety Regulation 2013.
Testing as part of regular maintenance
Interference tests need to be repeated when:
- a request is received from the Electrical Safety Office
- the system or method of operation is changed
- an anode forming part of the system is replaced
- a system is re-registered.
Testing by the regulator
If required by the Electrical Safety Office, you must give access to the system and provide facilities to further test it.
If the system does not comply with the requirements, you must pay all indirect and overhead costs the Electrical Safety Office made while testing.
Recordkeeping requirements
You must keep test records for 10 years if:
- the system is an impressed current cathodic system
- the system is a sacrificial system that has a total anode mass of more than 25kg.
These records must be available within 14 days, if requested by the Electrical Safety Office.

Registering your cathodic protection system
Impressed cathodic protection systems capable of delivering a current greater than 0.25 must be registered through the Electrical Safety Office Cathodic Protection Registrations Online system.
The owner is responsible for ensuring the system is:
- not operated unless registered
- operated according to the requirements of the cathodic protection standard
- tested according to the testing requirements of the Electrical Safety Regulation 2013.
Registrations are valid for 5 years unless cancelled during this time. You must re-register before the expiry date if the system is still in operation. The system must be retested before each re-registration in accordance with section 244 of the Regulation.
The owner must immediately advise the Electrical Safety Office of any changes to the registered cathodic protection system's operation by making an application via the Cathodic Protection Registrations Online system.
The owner must advise the Electrical Safety Office within 30 days via Cathodic Protection Registrations Online if:
- their address changes
- or
- the system is removed or made inoperable.
The owner may engage specialist consultants to conduct this work on their behalf.
