AC Type RCD No PV or Car Charger C3 or C2

Davies Gareth

For a standard domestic Install, split board with 2x Type AC main switches.

No PV or Car Chargers should this be a C3 or C2?

Thanks in advance

    Yesterday's announcement from the Government: https://www.gov.uk/government/news/government-to-go-further-and-faster-in-becoming-energy-secure

    If plug-in PV is being pushed as a way forward, and these are to have a UK standard plug (although BS 1363-1:2023 Clause 5 states that the UK plug shall not be used for connecting generators) then certainly in rented homes, and in flats (rented or otherwise), for the installation to be considered safe, surely:

    1. RCDs (RCCBs and RCBOs) for socket-outlet circuits (and upstream distribution circuits if applicable) would have to be at least Type A (because of the way inverters operate, but also for the existing PV inverter standard BS EN 62109-1, this is stated as a requirement for 'pluggable type A' equipment (i.e.. with a standard plug) to be compatible with Type A RCDs; and

    2. RCDs (RCCBs and RCBOs) for socket-outlet circuits (and upstream distribution circuits if applicable) would have to be bidirectional (Regulation 530.3.201 introduced in Amendment 3); and

    3. RCDs (RCCBs and RCBOs) for socket-outlet circuits would have to disconnect all live conductors (see Regulation 551.7.1)?

    The average consumer will have no idea what sort of RCDs they have.

    They will buy a balcony solar kit and hang it up. They will plug it in and it will work. Nobody will be electrocuted and the house won't burn down and they will be happy with that.

    They will be happy until something does happen, it's put forward that the RCD didn't operate and that might have saved a life ... and then all hell will break loose; and it will, of course, be our fault !

    Agreed

    They know even less about BS7671 or BS1363

    Agreed

    Therefore Product specification and/or requirement need to deal with it for the UK.  Very rare that a consumer will consult BS7671 or BS1363 while to shop on Amazon (other retailers are available)

    Not sure how the product standard could sort out some of the issues (e.g. incorrect type of RCD/RCBO, unidirectional RCD/RCBO, and single-pole RCBO)?

    product standard for balcony solar could mandate an RCD plug for example.
