Regulation 514.12 (Notices: periodic inspection and testing) now contains an exception for domestic (household) premises in certain situations.
Regulation 411.3.3 has been redrafted and now has three indents. There is still an exception to omit RCD protection where, other than BA1, BA3 or children (BA2, BA3) and mobile equipment (not exceeding 32 A) for use outdoors, a suitably documented risk assessment determines that RCD protection is not necessary.
About the IET Wiring Regulations
Ultimately preventing a collision is the single most important thing. So, if the action of the give way vessel alone isn’t sufficient to prevent a collision or it takes no action at all, the stand on vessel must also take action. If a collision does occur, then both vessels may be found to be at fault to a certain extent. Get to grips with the rules of the road CEF's Head of Technical Solutions Darren Staniforth and electrical legend Dave Austin will give you the lowdown: Modifications have been made to Regulation Group 543.7 concerning earthing requirements for the installation of equipment having high protective conductor currents.
There have been some structure changes, including the introduction of a new chapter (chapter 46) and a rework of chapter 53. The first step to answering a real life problem or any exam question for that matter is to ask yourself. ‘What part of the book does this relate to?’ The following paragraphs review how a specific ‘part’ of the book may materialise in an examination question format. We’ll be using section 6 for this, which alludes to the inspection and testing of electrical installations.Regulation 443.5 (Risk assessment method) has been deleted and Annex A443 (examples of calculated risk level CRL for use of SPDs) has also been deleted. Section 514 - Identification and notices There are 38 separate rules within the COLREGS although some of the regulations are only mandatory for larger vessel, in principle they do apply to all vessels. Changes include the addition of new regulations (relocated from Chapter 53) covering the impact and the installation of heating cables. Chapter 82 - Prosumer’s low-voltage electrical installations
Chapters 8.1 to 8.3 - amended in readiness for the carbon reduction requirements expected in the Future Homes Standard. New guidance on heat pump design and specification/certification requirements; solar thermal systems; space heating systems

With appropriate preparation, study, and following the tips in this post, you will be well prepared to pass the 18th Edition exam.
