If you plug it in, it gets test and tagged.
That’s a broad rule-of-thumb you can use as a starting point for any test and tag program.
We are taking about are extension leads, computers, power tools, heaters, floor polishers, lamps, battery chargers, laminators, flood lights and more… the range of appliances is wide and varied. (see note below for a more technical explanation)
Some appliances, such as plug-in adaptors and portable safety switches, do not have a flexible supply lead but are still required to be test and tagged.
Appliances that are in a fixed location are also included ie those bolted to a work bench or floor but have a flexible supply lead and connect to the supply via a power point.
RCDs, also known as safety switches, in fixed locations such as switch boards, or installed in power board, lead or supply cord also need to be test and tagged on a regular basis. RCD testing also includes checking the The trip time is the measurement of the time taken for a Residual Current Device (RCD) to trip (break the circuit) when a value greater than the rated tripping current of the RCD is detected. The measurement is recorded in milli-seconds. to ensure it is reacting within the prescribed limits.
Test and tagging is required to be performed on appliances used in workplaces regardless of type or size. This not only includes workplaces were people are engaged in paid employment but also volunteer organisations, not for profit organisations, meeting places such as community centres and club rooms, public places and so on.
Test and tagging can only be performed by a suitably trained and qualified person.
Note: Test and tagging is performed on Low voltage operates within the range of 51V - 1,000V AC or 120V - 1500V DC For test and tagging purposes these appliances present a risk of electric shock. single phase and poly phase (typically) three phase appliances that connect to the power supply by a flexible cord or connecting device.
