Electrical Condition Report
All electrical installations deteriorate with age and use. They should, therefore, be inspected and tested at regular intervals to check whether they are in a satisfactory condition for continued use. We call these safety checks an Electrical Periodic Inspection Report. Faulty and old wiring is one of the main causes of electrical fires in the home. By checking the condition of your wiring, sockets, switches and other accessories you can reduce the risk of an electrical fire. Below are some of the items covered in the Electrical Periodic Inspection Report.
The inspection will:
- Reveal if any of your electrical circuits or equipment are overloaded.
- Find any potential electric shock risks and fire hazards.
- Identify any defective electrical work.
- Highlight any lack of earthing or bonding.
- The condition of your wiring
- Highlight items that don’t comply with the wiring rules

An earth loop impedance test will be done on each circuit and the readings provided in the report. A circuit should be provided with an RCBO and for this RCBO to work correctly the earth loop impedance has to be a satisfactory reading as outlined in table 8.1 of the Australian Wiring Rules 3000.2007. A standard power circuit would have a 16 amp RCBO. The maximum earth fault loop impedance reading of that circuit should be no more than 1.92 ohms. If the earth fault loop impedance is more than 1.92 ohm the RCBO will not work quickly enough and could result in an electric shock under fault conditions.

Who should carry out the periodic inspection and what happens?
The inspection takes into account all the relevant circumstances and checks on:
- The adequacy of earthing and bonding.
- The suitability of the switchgear and control gear. For example, an old fusebox with an asbestos back board, ceramic fuses, or a mixture of both will need replacing.
- The serviceability of switches, sockets and lighting fittings. Items that may need replacing include: older round-pin sockets, round light switches, cables with fabric coating hanging from ceiling roses to light fittings, black switches and sockets mounted in skirting boards.
- The type of wiring system and its condition. For example, cables coated in black rubber were phased out in the 1960s. Likewise cables coated in lead or fabric are even older and may well need replacing (modern cables use longer-lasting pvc insulation).
- Sockets that may be used to supply portable electrical equipment for use outdoors, making sure they are protected by a suitable residual current device (RCD).
- The presence of adequate identification and notices.
- The extent of any wear and tear, damage or other deterioration.
- Any changes in the use of the premises that have led to, or may lead to, unsafe conditions. The competent person will then issue an Electrical Safety Report detailing any observed damage, deterioration, defects, dangerous conditions and any non-compliances with the present-day safety standard that might give rise to danger. If anything dangerous or potentially dangerous is found, the overall condition of the electrical installation will be declared to be `unsatisfactory`, meaning that remedial action is required without delay to remove the risks to those in the premises.
Portable Appliance Testing
We can also carry out Earth fault loop impedance testing and RCD testing at the same time to ensure complete safety in the work place.
