What should an RCD test reminder label say?

At minimum the label should state the test interval the site uses and identify which circuits the RCD protects. Workplaces often add space for the last test date and next test due, matched to the site testing program.

Where should RCD labels be placed?

Next to the RCD on the fixed part of the board, not on a removable cover or the door, where the test button is in view. Engraved laminate labels are a common choice because the text is cut into the material, not printed on.

RCD Test Labels & Requirements Australia (AS/NZS 3760)

RCDs (residual current devices) save lives — but only if they work when they're needed. That's why Australian standards require RCDs to be tested regularly, and the test reminder label on the switchboard is a key part of making sure it actually happens.

This guide covers what RCD labels are required under AS/NZS 3000 and AS/NZS 3760, how often RCDs need to be tested, and what your switchboard labels should say.

Why RCDs Need Labels

An RCD only protects you if it is working. Over time, dust, vibration, humidity, and electrical stress can cause the internal mechanism to stick or fail. Regular press-to-test checks confirm the trip mechanism is still operational.

Without a visible test reminder, these checks tend to get skipped — and a stuck RCD is an RCD in name only. The label exists to make sure the occupant or maintenance team knows the test is their responsibility, and how often to do it.

RCD Testing Frequency Requirements

Testing frequency depends on the installation type and is primarily driven by AS/NZS 3760 (in-service safety inspection and testing of electrical equipment) and WHS regulations.

Installation Type	Push-Button Test	Operating Time Test
Residential (owner-occupied)	Every 3 months (recommended)	Every 2 years
Rental property	Every 6–12 months (state-dependent)	At change of tenancy
Commercial office	Every 6 months	Every 2 years
Commercial kitchen / wet area	Every 3 months	Every 12 months
Construction site	Daily visual + monthly push-button	Every 3 months
Hostile environment (hire equipment)	Every 3 months	Every 6 months

State variations apply — Queensland, Victoria, and WA each have specific rental RCD testing rules. Always check your state regulator's requirements in addition to AS/NZS 3760.

What the Label Should Say

Basic Test Reminder Label

The simplest RCD label reminds the user to press the test button regularly. A typical format:

TEST RCD QUARTERLY — for residential
TEST RCD MONTHLY — for commercial
PRESS 'T' BUTTON TO TEST — instructional version

Detailed Test Label

For commercial and industrial boards, a more detailed label is often fitted alongside the RCD:

Device identification (e.g., "RCD 1")
Test frequency ("Test every 3 months")
Last test date field (space for a service sticker or written update)
Next test due date field

RCD Identification Label

On boards with multiple RCDs, each needs its own identification label showing which circuits it protects. Example: "RCD 1 — LIGHTS & GPOs LEVEL 1".

Label Placement

RCD labels should be fitted:

Directly adjacent to the RCD — not on the door, not on the panel. The label must be visible when the user is looking at the RCD itself.
Where the test button is visible — the label and the button should be in the same glance.
On permanent engraved material — paper labels fall off, handwriting fades, and Dymo tape peels. Engraved traffolyte is the standard.

Common RCD Labelling Mistakes

No Test Frequency Specified

A label that just says "TEST RCD" doesn't tell the user how often. Specify the interval.

Missing RCD Identification

On multi-RCD boards, if each device isn't individually identified, the user can't tell which circuits lose power when they hit the test button — so they don't test it.

Confusion Between Main Switch and RCD

On RCD main switches (where one device serves both functions), the label should make clear that it is an RCD and needs periodic testing, not just a main switch.

Labels on the Front Panel Only

If the label is on the removable front cover and the cover is off, the user loses the reminder. Labels should be on the fixed panel or directly on the DIN rail cover.

RCD Labels for Rental and Hire Equipment

If you are labelling hire equipment or rental switchboards, AS/NZS 3760 requires:

A test tag or label showing the date of last test
The tester's name or company
The next test due date

These are usually separate service tags, not engraved labels — but the permanent RCD identification and test-reminder labels still need to be present on the equipment.
