and Tagging

Test and Tag Services

• Test and Tag

• RCD (Safety Switch) Testing

• Emergency and Evacuation Light Testing

• Recommendations for dealing with Failed Appliances

• Geographical regions serviced

• Out of hours service

We carry out a comprehensive test regime on all mains-powered equipment connected by a flexible cord to a power outlet in accordance with AS/NZS 3760. This starts with a detailed visual inspection for visible defects that may compromise the safety of the appliance.

This is followed by a sequence of electrical tests. The test sequence will vary according to the type of appliance but fall into 3 main categories: Earth Circuit Integrity, Insulation Integrity and Polarity.

• Earth Resistance:

  This tests the ability of the earthing circuit of the appliance to carry fault current to earth. Double-Insulated appliances are not subject to this test. This can be either a Bond test or Screen test depending on the type of appliance.

• Insulation Resistance:

  This tests ability of the insulation of the electrical conductors to prevent any current from "leaking" out of the wires. This usually involves both a regular Insulation Resistance test and an Earth Leakage test.

• Polarity:

  This test confirms that the Active, Neutral and Earth conductors are correctly connected at each end of the power cord. This is usually only done on extension cords. detachable power supply cords (as used on computer equipment) and powerboards.

We can carry out these tests on both single phase and 3 phase appliances.

The installation of Residual Current Devices is recommended in all workplaces and homes. Workplaces often use multiple RCD-protected power circuits to prevent an unsafe appliance from blacking out the entire workplace. Powerboards with integrated RCDs are also common in workplaces. Like all machines, these can become faulty or their calibration drift over time.

• Trip Current:

  If the trip current is too high, this can allow excessive fault current to flow to earth, either through the earth wire or worse, through the operator. Alternatively, the RCD may trip at too low a fault current, causing nuisance tripping that disrupts the workplace and reduces productivity.

• Trip Time:

  If the time it takes the RCD to trip is too long, a fault current may flow through the operator long enough to be fatal.

Q-Safe Electrical Testing and Tagging can test the functionality and calibration of all RCDs in the workplace and ensure they are helping to keep your workplace safe from electrical hazards.

Q-Safe Electrical Testing and Tagging can also test the Emergency and Evacuation Lighting system to ensure it is operating in accordance with AS 2293. The 2 main tests performed are: Test with integral switch and testing of backup battery capacity.

• Test with integral switch:

  This test is done by operating the switch integral with the emergency light to ensure that the battery powered lamp functions.

• Test backup battery capacity:

  This test is done by disconnecting mains power to the emergency and evacuation lighting system and confirming that they continue to operate for the duration specified in AS 2293.

Since many businesses rent or lease premises, the responsibility for the correct operation is often the building owner or landlord.

Most appliance failures occur with low value items such as extension cords and power boards. Initially they are labeled as Dangerous and quarantined for either disposal or repair. Typically, these low value items are disposed of and replaced with new items. More expensive items often fail due to a fault in the power supply cord. These can often be economically repaired with a new cord.

For tradespeople who don't want to have their work disrupted by the Test and Tag process, we offer an evening/overnight service. Just drop the electrical equipment off when you finish in the afternoon and they'll be ready to pick up later that evening or first thing the next morning.

For offices and factories, we can test out of hours, either in the evening or weekend.
