What is an R.C.D.?
R.C.D. is an acronym for Residual Current Device, or sometimes better know as a Safety Switch. All buildings have RCD's and most building have many of them. RCD's are very important, as they are the last line of defense & can turn off the power, if someone was in risk of getting electrocuted.
Why do RCD's require testing?
RCD Testing is the process of testing and tagging your RCD's (Safety Switches). This is done through two testing processes:
- Push button Testing (every 6 months) - Push button testing is important because RCD's are quite often stored in dusty/dirty back rooms or warehouses. RCD's need to work in one hundredth of a second, so it's important to ensure that they can trip freely.
- Operating Time Testing (every 12 months) - Time Testing is done by plugging our Portable Appliance Testing into electrical outlets throughout your premise and measuring the time it takes to trip your RCD. If the mesured time falls inline with Australian Standards the RCD will pass the test.
Is RCD required by Legislation?
Yes, your RCD's are required to be tested every 6 months under Australian Standard AS/NZ 3760:2010.
