    I’ve bought some ip57 outdoor mains voltage festoon lights. They are made with two core flex with a plug on one end and a connector on the other end to join another set if required, this has a screw on lid to make it water proof. I would like to cut the run in half and use two separate runs wired in to water proof junction boxes. The problem is that this would leave exposed ends of cable. What would be the best way to terminate the open ends of this flex to make it waterproof?
    Thanks folks.

    Heat shrink sleeving that is lined with hot melt adhesive is one option.

    In the 'pro' environment 16A Ceeform plug and socket are fitted, that way the 2 halves can be joined when used elsewhere.

    I know that it is commonly done that way but it has always seemed to me to be extremely bad practice to do so because festoon is nearly always 2 core cable and therefore leaves the socket without a CPC.

    Lawn mover plugs and sockets seem a better idea upload_2021-7-3_2-28-7.png only two pin so unlikely for errors, the Telco IP68 Plug & Socket
    Waterproof Connector seems better upload_2021-7-3_2-31-1.png but they are three pin, however if never going to join again @bernardgreen has given best method.

    I had some Christmas lights festoon idea, and I was never really happy about leaving outside for an extended time, over Christmas OK but not really spider proof, would want RCD protection and not were if it does trip loose other items in the house.

    I'm inclined to agree with robin on this one, "manage the site" doesn't seem like a good excuse for leaving a socket of a relatively common type (not as common as a 13A socket but not exactly rare either) lying around with a missing earth.

    Managing the site is what every temp power supplier does in my experience and yes they are a common connector which is exactly why they are fitted at both ends of hundreds, if not thousands, of miles of festoons held in stock by temp power providers, plant hire companies and event/exhibition providers the length and breadth of britain.

    The subjcts has been discussed ad infinitum by many people over the year and the final consensus is always CeeForms and manage the risk.
    My preferred idea was to use the European standard but then we have to add an unnecessary layer of thousands of miles of extention lead hire stock to the system.

    Well the 2 pin are not weather resistant and the waterproof type you show are not relaible as has been proved by those who have thied them for this purpose.

    Thanks for all the tips guys, it looks like adhesive lined heat shrink is the way to go. Unless I feed it in to the shed with a IP rated junction box at the end of the run and fit a light in my shed. Its only a small tool shed so only very occasional use and I can live with having to have the festoon lights on to use the shed light. Not perfect but better than no shed light at all?

    Which would contravene the Regs as you should not supply a light fitting in that way with 2 core cable.
    Personally i would just fit an Ip rated box on the end with 2 connecters inside

    What do you mean? All junction boxes are IP rated even if the rating is zero.

    In that case he should say so and quote the IP rating he wants.
