Electrical Test and Tag in Southern Adelaide, Fleurieu Peninsula & Surrounds

Cozco Electrical Contractors use licensed electricians to carry out electrical Test & Tag work for our clients. This means we can also repair most items whilst on site if required.

Our testers use a Portable Appliance Tester (PAT) and work in accordance with the current Australian Standard, AS/NZS 3760:2003 that specifies the tests required to be conducted in order to confirm the electrical safety of an item.

Whilst the Australian Standard does not mandate a PAT should be used to conduct these tests, the use of a PAT remains one of the most comprehensive and efficient methods of ensuring an item’s electrical safety.

Australian Standard test checks

Insulation Resistance

This test checks for the integrity of the insulation that is protecting users from the live parts within the appliance.

Leakage Current Testing

This test involves "powering up" the appliance and measuring any current leakage.

Polarity

A polarity test is conducted on a flexible supply cord with a rewireable plug or socket to ensure the active and neutral wires are connected to the correct terminals.

Earth Resistance

An earth resistance test will confirm whether the earth connection of the equipment, between the plug and exposed external metal parts, or the plug and the socket, is no greater than 1 ohm. One method of testing this is to conduct an earth continuity test. The test can be conducted using a PAT, multimeter or insulation resistance tester; however it does not take into account any damage to the earth connection or conductor and hence could be considered less effective than other methods of measuring earth resistance.

We would recommend an earth bond test be conducted by a PAT that is capable of applying a higher current to determine whether in the event of a fault, the equipment can handle that fault current correctly, and to measure earth resistance.

Visual Testing

Approximately 90% of faults are identified from visual inspection prior to the completion of the required electrical tests. It is important to note that a true visual inspection is not a quick look at an appliance or even the application of a pass tag without even looking at the appliance.

A visual inspection conducted by a reputable service provider involves a comprehensive inspection of flexible supply cord, plug, appliance and socket. Covers and guards are checked to ensure they are attached, appliances are checked for rattles indicating the presence of small foreign objects that may interfere with the safety of the appliance, and Class II appliances are checked for deep engraving which may impact on the insulation of the appliance.

Cozco Electrical Contractors will keep your test and tag register up-to-date for you and provide you with a copy after each service.
