Electrium sheds light on 18th Edition RCDs E
Regulation 531.3.3, for example, is new to the
regs book but the principle of this regulation is not new at all. For example, regulation 132.8 (17th and 18th editions) requires protective devices to operate at values of current, voltage and time that are suitably related to the characteristic of the circuits and possibilities of danger. Four types of RCD are mentioned in
regulation 531.3.3 which also requires the appropriate RCD to be selected from those four options - Type AC, Type A, Type F, or Type B. Each RCD type has different operating characteristics to suit particular applications - including those where DC components and varying frequencies are present. The requirements here are clearly stated. Designers and installers must select and specify the correct device for each circuit or item of equipment being protected, and that choice must be made through a proper technical assessment.
lectrium has recently come across reports that an RCD company is encouraging its customers to standardise on one
type of RCD. This type of advice doesn’t actually follow the requirements within the wiring regulations and it may prevent designers from carrying out proper electrical design assessments. Even worse, it could lead to the use of inappropriate devices that are not suitable for the intended purpose.
SELECT highlights safety risks of counterfeit manuals T
he industry body for Scotland's electrical
sector professionals, SELECT, has once again highlighted the ongoing threat of poor and potentially dangerous electrical work, as it is revealed that counterfeit copies of vital wiring regulations are being offered for sale.
The bogus PDF copies of BS7671:2018, the IET (Institution of Engineering and Technology) Wiring Regulations, could be devastating for electrical professionals, with missing or corrupted information potentially leading to unsafe work and risking fire, electric shock or even death. The latest counterfeiting activity reinforces the message that SELECT has been
Dave Forrester, Head of Technical Services at SELECT
promoting in the Scottish Parliament in its campaign, backed by the Scottish Joint Industry Board and Unite the Union, for recognition of electricians as a profession. SELECT’s case was pressed recently (October) in a Holyrood debate in which evidence was presented of unqualified and under-qualified people who masquerade as electricians endangering public safety by carrying out work across Scotland. The IET is now taking action to combat the counterfeiters by inserting a
hologram in its Regulations, commonly known as the 18th Edition, to help users identify genuine copies. It contains the IET logo and the word “Genuine”.
