Carnegie has a mix of older brick units and renovated weatherboards where DIY changes and ageing switchboards can leave outlets miswired. A polarity check helps confirm power points and circuits are wired safely before you move in or rent out.

Our comprehensive service includes everything you need to make an informed decision about your property.
We test accessible outlets to confirm active, neutral and earth are correctly connected. Incorrect polarity can make appliances and light fittings unsafe even if they appear to work normally, increasing shock risk and reducing protection from safety devices.
We visually assess the switchboard for signs of overheating, ageing components, poor labelling, missing blanks, or unsafe modifications. Switchboards are a common pinch point in older Carnegie homes that have added higher-load appliances over time.
We check whether safety switches are installed for relevant circuits and perform basic checks (where safe and accessible) to see if they operate via the test function. RCDs are critical for reducing electric shock risk, particularly in wet areas and outdoor circuits.
We inspect visible wiring where accessible (for example, near the switchboard, under-house areas where safe, and surface-mounted cabling) to identify damage, unsupported runs, heat exposure, or DIY-style connections that warrant an electrician’s follow-up.
We confirm smoke alarms are present and note installation and placement considerations based on accessible areas. Smoke alarms are a key safety layer, and older Carnegie properties can still have outdated units that should be assessed for replacement by the owner/electrician.
Where we identify safety concerns, we explain what the issue means, where it’s located, and what type of licensed electrical work is typically required. This makes it easier to request accurate quotes and prioritise urgent hazards before settlement or tenancy.

Our assessment focuses on practical electrical safety risks. We perform polarity testing at accessible power points, visually review the switchboard for hazard indicators, check safety switch (RCD) presence and basic operation where safe, and note accessible wiring concerns. We also check smoke alarm presence and general positioning. Any issues found are documented with clear recommendations for follow-up by a licensed electrician.
Yes. A circuit can appear normal while still being wired incorrectly. Reversed polarity can leave parts of appliances or fittings energised in ways you don’t expect, increasing shock risk and undermining safety protection. A polarity test is a quick way to confirm the active and neutral are correctly connected at outlets, which is especially important after renovations or when you don’t know who completed past electrical work.
We carry out a non-invasive safety assessment based on safe access and visibility. We visually inspect the switchboard and may open the external cover where safe to do so, but we don’t perform electrician-only works or dismantle components that require a licensed electrician. If we see signs of overheating, damage, poor workmanship, or missing protection, we’ll document it and recommend appropriate electrical rectification.
Carnegie’s mix of older brick apartments and renovated houses means we often see partial upgrades—new kitchens and added outlets paired with older switchboards or mixed wiring methods. This can lead to inconsistent safety switch coverage, unclear circuit labelling, and outlets that have been altered over time. A polarity-focused assessment helps pick up wiring errors that can sit unnoticed behind modern fittings.
Ensure we can access the switchboard, garage or side passage, and any accessible outdoor power points. If the property is tenanted, let occupants know we may test the RCD button and check a selection of outlets, which can briefly interrupt power on a circuit. Share any known issues like nuisance tripping, flickering lights, recent renovation details, or areas with a burning smell so we can target checks.
