do all circuits need rcd protection 18th edition

Generally all the domestic circuits I install do have that RCD protection, don't get hung up on lights that is just the latest group of domestic circuits that must have RCD protection and normally all of the circuits I installed do so, but up until now you justifiably omit it if you got the circuit … The 18th edition of BS7671 has introduced a requirement to provide RCD protection to circuits supplying lighting fixtures. Todays 18th edition consumer units incorporate an enclosure manufactured from non-combustible material, i.e. I am given to understand that as of Jan 1st 2019 the 18th edition of the Wiring Regs stipulate that *all* electric vehicle charging points (EVSEs) must be protected with a 'Type B RCD" where the 'Type B' relates to the sensitivity of the RCD to ac, pulsating ac *and steady dc leakage currents*. Socket and all bathroom circuits should. The 18th Edition to the Wiring Regulations, due to publish 1st July 2018, has, amongst other areas, resulted in changes in the regulation relating to RCD's. 411.3.4: Again 30 mA RCD additional protection for all lighting circuits. The latest amendment to the IET’s Wiring Regulations reinforces the requirement for using residual current devices (RCDs) in non-domestic environments. In brief, some circuits need not be RCD protected. a full metal enclosure. However, in most instances, general 13A socket outlets need RCD protection, as do any 16A or 32A sockets (whether single or 3 phase). Whilst there was previously no strict requirement to RCD protect light fittings, there was a requirement to provide this protection to cables which … Must be used with MCB for overcurrent and short circuit protection. Ideally, budget allowing, there is a good safety argument for RCD protection of all domestic circuits. Under the new 18 th Edition, all final circuits rated 32A or less need RCD protection to at least 30mA earth leakage. Sockets Rated 32 Amps or less require RCD /RCBO protection to 30mA. General lighting the odd fused spur radial need not. With the 18th Edition of BS 7671 just around the corner, we take a look back at the last amendment to the 17th Edition of BS 7671 and the requirements for using RCDs in non-domestic environments. Final circuits providing 30 mA protection. https://professional-electrician.com/18th-edition/18th-edition-5-key-changes CBR:MCCB + Residual current protection (Non-domestic >100A) AFDD: RCBO* + Arc Fault protection. I would not consider 30mA RCD protection on all final circuits to be a good reason not to have an upfront S-type RCD, not least to provide a level of defence against tails making all earthed metalwork in the installation live. RCBO: MCB + Residual current protection. There is an exception to omit RCD protection where, other than a dwelling, a documented risk assessment determines that RCD protection is not necessary. There is no exclusion for 3 phase circuits, so this will cover all 16-amp, 32 amp, single and three phase sockets. The 18th Edition Regs list the following RCD formats: RCCB:Residual current protection only. Memera full metal consumer units The Eaton range of full metal consumer units provide a suite of products to meet the requirements of BS7671:2018 18th Edition IET wiring regulations. The impact of the 18th Edition (BS 7671:2018) - RCD protection for all socket-outlets The new functionality has been incorporated into the Smarter EI&T® features and work flow. RCD protection.
