Public Consultation: PAS 63100 Electrical installations – Protection against fire of battery energy storage systems for use in dwellings – Specification

gkenyon

The Draft of the new PAS 63100 standard for protection against fire of battery energy storage systems for use in dwellings is now available for public comment on BSI’s Standards Development web-site.

The public commenting period commences 26 June 2023, and on closes on 24 July 2023.

This topic is directly related to domestic storage installations accordance with BS 7671 and the IET Code of Practice for Electrical Energy Storage Systems.

  • No need for this, just a requirement for a bunded reinforced seperate building at the side of the house for battery storage. Keep it well way from the main dwelling and there's no need for a separate wiring standard.

    That would mean that a lot of people wouldn't be able to have it though. Not everyone has the space for a separate building. I have seen a couple locally where the batteries has been put in the roof space. I only know that as i was asked to install a mains linked smoke detector in there so i presume that is already a requirement.

    It's not a "wiring standard". BS 7671 is referred to as the main electrical installation standard.

    Worth a read as to what the draft provides for.

    Some I've seen, are actually just monobloc batteries (equivalent to a car battery, perhaps with shrouded connectors, but all the same ...)  placed in the loft or on the floor of a garage, with a simple gG-type fuse carrier on the wall under the inverter (no real adequate overcurrent protection within the "free to move" monoblocs close by).

    Just imagine an inquisitive child opening a gG fuseholder on-load (and drawing a beautiful DC arc), for example.

    To be fair the ones i have seen were in big metal cabinets so looked a pretty good install.

    I don't think the take-up of such will become mainstream any time soon, the costs are too high for most folk. Same with EVs, whose market is now stalling as the chickens come home to roost.

    Might not be an option. With the latest update to the SAP calcs, we're finding some residential developments require storage alongside the PV array to get a satisfactory result. At least the cost occurs during the construction and can/should be accounted for by developers (albeit this will undoubtedly be passed on in house prices) but ongoing maintenance and replacement will be another 'new technology' for homeowners to wrestle with. Main struggle is getting adequately sized utility spaces within the dwellings to house everything.
    As for EV uptake, our hands will be forced eventually unless we give up driving for public transport.
