Really unusual question.....

tonydon
Does anyone know of any  FUSED  16A industrial IP67 plugs......   (blue plugs)


I have tried everywhere.......


really unusual use ... very long story  ......... but need to be fused

    IP67? Blue caravan plugs are only IP44. Please tell all. Can't the supply sockets be fused at 16 Amps? That may be the solution.


    So you are looking for these with an internal fuse.

    Thanks for the reply zoom up


    I work in TV production. 

    It is industry standard that the supplies for temporary sets are fed via 16A Ceeform leads.


    The problem with this is that we are often asked to fit blue plugs to items with small conductor size ... eg a cord grip lamp holder lead set.

    these are often in shot for 10 minutes then removed.  But, obviously their cable is only 3A.......  just one of many examples........


    if I could find fused 16A plugs that would solve the issues in the simplest way.......


    I could install inline fuseholder within the plugs but it would be time consuming.....

    There might not be a real problem there. The fuse in a 13A plug is only there to protect the flex from faults - i.e. fault currents of hundreds if not thousands of amps - it's up to the appliance itself not to overload. A 16A or 20A protective device (supplying the 16A socket) will open almost as quickly as a 3A fuse under those sort of conditions. That's why most of the world doesn't have fuses in their plugs. We only need them to allow us to have 30A+ protective devices on our socket circuits.


    If you really want a fuse then perhaps a 16A plug connected to a 13A trailing socket, so the 13A plug plugged into that can be fused at what you like (even if it is then connected to a 16A trailing socket to match the appliance).

    I agree that a standard non fused 16 amp plug should be fine provided that the lamp or other appliance is relatively modern and is fitted with at least 0.75mm flex. Research has shown that 0.75mm flex can be safely protected against short circuit by a fuse  of up to 15 amps or an MCB of up to 20 amps.


    Remember that the same appliance is almost certainly used in mainland Europe and is connected to an unfused plug on a 20 amp circuit, and that no one worries about that.

    There is no provision for fuses in the standards for the CEE form plugs and sockets - the intention is that you fuse at the origin. 16A sockets should at most be on a 20A breaker.

    As noted no normal  CE marked appliance and cable will blink at being on a 16A C type breaker.

    Two short leads? One with 16A plug and 13A socket, the other with a 13A plug and a 16A socket. Put them in series if you really need the 16A plug on your stage equipment.

    But if anyone ever decides to connect a 16A load to the socket, you can be reasonably sure that the 13A fuse won't blow, but the plug may melt after a few hours.  It's a bit of a flaw in the design of the BS1363A plug.

    So does all the stage lighting fittings have a built in fuse holder and fuse?
