Our RCD testing team performs each test in accordance with current legislation. Last financial yearProlux Electrical Contractorstested over 250,000 RCDs in Victoria and Queensland. As such, children were put at risk and exposed to socket outlets without residual current protection. Generally, used where normal current is more than 100 Amps. Where all circuits would be fitted with RCDs following a switchboard replacement, this can quite often cause nuisance tripping. 10kA RCDs would be typically found on protected sub mains or underground circuits where the fault current may be much higher under fault conditions.

If a particular circuit is critical for safety services or business functions, surely socket-outlets would not be the preferred option, to prevent accidental "unplugging". Your making your report to current regulations "If they are installed to a previous edition of regulations then that's ok' ( I know my quote is not word for word). Thats why its important that electricians who specialise in such maintenance are engaged for Planned Preventative Maintenance (PPM). These types of RCDs protect the circuit from overload, as well as earth leakage faults; therefore called an RCBO. We have added in a battery with isolation switch and fuse box. I've got a job where I'm installing dado trunking on the floor of an office for sockets and data. The important question is whether commercial premises should haveRCDprotection.

An RCD, or residual current device, is an electrical life-saving device which is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare wire. RCDs must also protect power-outlets in an alteration (according to the requirements for new circuits in the area where they are located). Additionally, protection must be provided in the event of a failure in basic protection or carelessness by the user. Such omission is not permitted for an installation in a dwelling; it is permitted only for an installation in some other type of location (see indent (a) of the new version of Regulation 411.3.3). e. May I suggest that you read BS7671 411.3.4 that states that all circuits supplying luminares will be protected by 30mA RCDs. Under the new 18 th Edition, all final circuits rated 32A or less need RCD protection to at least 30mA earth leakage. This will undoubtedly make the workplace a safer place.. Also, the added feature for sprinkler protection to commercial classifications does not provide appropriate minimum or comparative levels of protection to that of LPC rules and BS EN 12845. To determine the increased risk of electroshock, as electrical contractors in Perth, we consider electrical equipment (e.g.,is the electrical apparatus Class 1, exposed conductor parts), and external influences (e.g., exposure to elements, vibrations, production line, and the connection with the supply). cheers mate, is that a REQUIREMENT tho or preference? Prior to 2018 residential RCDs did not always have the same fault current rating (fault current rating is measured in kA) as industrial and commercial RCDs. Electrical Safety Advice | ElectriciansForums.net. Quite frankly, the choice of RCDs and their application has become nothing short of confusing.
