It is stressed that the exception may only be applied for a socket-outlet that has been provided for the connection of a particular item of equipment. In order for the omission of RCD protection to any socket-outlet on the basis of risk assessment to be permitted by Regulation 411.3.3, the risk assessment must determine that the RCD protection is not necessary. 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). Excessive DC current on an RCD-protecting AC supply could result in the failure to trip when an AC fault occurs. A new, revised version of Regulation 411.3.3, relating to RCD protection of socket-outlets, forms part of BS 7671:2008+A3:2015 (IET Wiring Regulations Seventeenth Edition), which was published in January 2015 and comes into effect on 1 July. Its not an uncommon occurrence to find incorrect type RCDs installed during testing. For compliance with Regulation 531.2.4, a socket-outlet should be connected to an RCD that serves a sufficiently small number of other socket-outlets or items of equipment, so that any protective conductor current that may be expected in normal service will be unlikely to cause unwanted tripping of the RCD. 1) In part 2 of the AMD2 Wiring, Theories, Regulations, Certification, Electrical Wiring, Theories and Regulations. *, Daikin Industries launches low GWP refrigerant, IOR updates guidance for non-flammable low toxicity refrigerants.

An RCD tester monitors the current flow through one or more circuits. Additional protection is required by RCDs if circuit protection on a switchboard has been removed. Each RCD type has different operating characteristics to suit particular applications - including those where DC components and varying frequencies are present. In some industrial environments 10kA RCDs or more are installed as 6kA arent sufficient enough for particular circuits. Unlike the current version of Regulation 411.3.3, the new version does not permit the omission of RCD protection to a socket-outlet just because the socket-outlet is for use under the supervision of skilled or instructed persons. The intent of this category is to simplify management of electrical safety based on the principles that electrical equipment is safe already (i.e . - Any circuits which serve lights within a domestic property must have RCD protection.
