Electrical enquiry questions

Find the answer for your situation

Use the questions below for a specific answer. For a fuller decision guide, the safety-switch page owns circuit-protection choices and the smoke-alarm page owns dwelling-status timing and alarm options. Keep your actual installation and proposed work in mind rather than assuming a general answer diagnoses the property.

For comparing a proposal, use the quote checklist. Existing records can help but are optional for an initial enquiry. You can start with the problem or outcome you want.

If you receive a shock or tingle from an appliance or metal fitting such as a tap, call Energex on 13 19 62 immediately. Keep clear, warn others and do not touch the switchboard, appliances or metal fittings until the property is made safe. For fire or life-threatening danger, call 000. Seek medical advice after an electric shock.

For choosing between a replacement fitting and a new light position, see the lighting installation guide.

Questions and answers

What does a safety switch do?

A safety switch disconnects the protected circuit when it detects current leaking to earth, reducing electric-shock risk. It does not make damaged equipment or unsafe work safe.

Is a circuit breaker the same as a safety switch?

No. Circuit breakers protect wiring and equipment from overcurrent. Safety switches reduce electric-shock risk. A combined device can perform both functions; the device and circuit coverage matter.

How can I tell whether my switchboard has safety switches?

ESO identifies a test button as a useful feature, but one device does not establish protection on every circuit. You can enquire without inspecting the board; a licensed assessment confirms actual coverage.

Can a home need more than one safety switch?

Yes. Different circuits can have separate protection. Power, lighting and fixed-equipment circuits should be considered individually rather than assuming one safety switch protects the whole house.

Can a homeowner install a safety switch?

No. Installing a safety switch is licensed electrical work. Describe the existing installation and proposed change; you do not need to select or fit the device yourself.

Can I test a safety switch myself?

ESO provides instructions for the device test button. Follow those instructions, allowing for the supply interruption. If it does not trip as intended, arrange licensed help. For a shock or tingle, keep clear and follow Energex’s immediate guidance instead.

What if a safety switch will not reset?

A circuit fault may be present. Do not force the switch to stay on or use repeated resets to diagnose it. A licensed electrician needs to investigate and repair the relevant fault.

How often should a safety switch be tested?

ESO recommends push-button testing every three months. Follow the device instructions and arrange licensed help if the test does not work as intended.

Will a safety switch protect me in every electrical accident?

No. Safety switches are not failsafe and do not protect against every kind of electrical accident. Faulty wiring or equipment still requires appropriate repair.

Can adding a lighting circuit change safety-switch requirements?

Yes. ESO says additional lighting and power-point circuits require safety-switch protection on both. The proposed work and actual existing coverage need assessment; a new light position is not proof that the board needs replacing.

When must an existing Queensland home have interconnected photoelectric smoke alarms?

Existing Queensland private homes, townhouses, units and manufactured homes must meet the interconnected photoelectric requirements by 1 January 2027. Sale, rental and new-dwelling categories have earlier or separate requirements, so identify the dwelling’s actual status.

Where are smoke alarms required in a Queensland home?

Requirements include bedrooms, the hallways connecting them and each storey. Where there is no hallway, an alarm belongs between bedrooms and other parts of that storey. A storey without bedrooms needs an alarm on the likely exit path. Placement also has clearance rules.

Can an existing home use battery-powered photoelectric smoke alarms?

Eligible existing homes can use compliant non-removable ten-year battery alarms. An existing hardwired alarm must be replaced with a hardwired photoelectric alarm. Existing wiring and the dwelling category determine the appropriate arrangement.

Must interconnected smoke alarms all be linked by new cable?

No. Required alarms can be interconnected wirelessly or by cable so they sound together. Electrical work for a hardwired installation requires a licensed electrician.

Who can install a mains-powered smoke alarm?

A licensed electrician installs a hardwired alarm connected to the electricity supply. A battery alarm does not itself need that mains connection; the dwelling and replacement rules still determine which alarm is suitable.

When should an older smoke alarm be replaced?

QFD says a faulty alarm or one more than ten years past its manufacture date needs replacement with a compliant photoelectric alarm. A hardwired alarm must be replaced with a hardwired alarm.

Who is responsible for installing smoke alarms in a Queensland rental?

The landlord is responsible for installing compliant alarms. Testing and cleaning during a tenancy have separate owner and tenant responsibilities. Use the rental status and current RTA guidance when planning work.

Can an ionisation-only smoke alarm meet the new Queensland requirements?

No. The Queensland requirements specify photoelectric alarms without an ionisation sensor, with the required interconnection and power arrangement. Identify which dwelling deadline and replacement rules apply.

Does every smoke-alarm replacement require an electrician?

No. Some compliant wireless battery alarms can be installed without electrical work. Work involving a mains connection requires a licensed electrician; changing a hardwired alarm to a battery-only one is not a general replacement option.

Do I need a licensed tradesperson merely to test and clean a domestic smoke alarm?

No. RTA says a qualified person is not required merely to test and clean a domestic alarm. Follow the manufacturer’s instructions; testing and cleaning are different from electrical installation work.

Can a new power point change safety-switch requirements?

Yes. ESO says safety switches must be fitted to power-point circuits when a new general power outlet is installed. Include existing protection in the assessment rather than assuming the outlet itself is the full scope.

Can I replace a fixed light fitting with a ceiling fan myself?

No. Replacing a fixed light fitting with a ceiling fan involves licensed electrical work. The selected fan, mounting and control arrangement also need assessment.

What should I check when choosing an electrician?

Check the current Queensland electrical contractor licence through the official Electrical Licence Search and discuss the actual written scope. A licence check does not tell you that a proposed product or installation design is suitable for your home.

Who should I speak to about changing a meter before switchboard work?

Start with the electricity retailer on your bill. Energex directs smart-meter requests to the retailer. Keep meter coordination and the planned board work clear, including any known building access arrangements; agree on the sequence for the actual property.

What permission should I arrange before adding a ceiling fan in a Queensland rental?

Obtain written permission before the discretionary fixture alteration proceeds. Applicable body corporate approval may also be needed. You can discuss a quote while permission is being clarified; permission does not establish mounting or product suitability.

Can a ceiling fan use both a wall control and a remote?

Sometimes, depending on the exact fan and approved accessories. Some Beacon models allow both controls; some remote kits replace the speed controller with an isolation switch. Keep the model and desired functions together and use its instructions rather than assuming controls can be combined.

How should I choose a ceiling fan for a low ceiling?

The fan’s installed dimensions, mounting options and manufacturer instructions matter. If you already know the ceiling height, include it; you need not measure before enquiring. Review the selected model and required clearance with the installer before buying.

What should I do if an installed ceiling fan vibrates or wobbles unusually?

Stop using a fan with unusual wobbling or oscillation and seek the manufacturer, service agent or suitably qualified help. Use the instructions for your actual model; do not continue using it or attempt suspension repairs to establish the cause.

What should I expect when an electrician investigates a safety switch that will not stay on?

Clarify the investigation scope and how findings will be explained before choosing a repair. Keep existing observations and known access restrictions with the enquiry. Do not force the switch on, repeat the fault or perform electrical measurements to help the assessment.

How do I decide whether my old switchboard needs an upgrade and room for future work?

Ask for an assessment of the existing installation and the changes you actually plan. Appearance or spare positions alone cannot establish protection, wiring condition or usable capacity. A useful recommendation distinguishes what can stay from what must change and explains why.

How can I compare an electrical quote or ask about a small group of jobs?

List each desired outcome separately and compare supply, installation, assumptions and exclusions. Clarify investigation charges and how extra work would be authorised. At handover, keep the certificate appropriate to the work with the agreed scope; equipment and installation certificates have different purposes.

Can a ceiling fan be installed where there is no accessible ceiling cavity?

An inaccessible ceiling cavity does not by itself establish that a fan is impossible, or that replacing a light is straightforward. The actual support, cable route and selected model need assessment. Describe known access constraints without opening the ceiling to investigate.

Does an unexpected ceiling-fan speed setting mean the wiring is reversed?

Not by itself. An unexpected speed setting does not diagnose reversed wiring. Check the exact model’s instructions and describe the behaviour; do not alter wiring or reverse connections as a test.
