    Could anyone advise wether the cbus wireless rf plug pack RELAYS are able to hold the inrush current from a 400 watt Metal Halide hibay fitting?

    I know that the 10A rating is derated to 2A for "fan start" but would this be able to hold up to a hibay inrush / start up current?????

    thanx in advance all :) :)

    A plug adaptor should have no problems whatsoever with a 400W hi-bay.

    As long as the warm-up current doesn't exceed the 10A product rating it will work just fine. The in-rush current at turn-on into a hi-bay is not as harsh as the in-rush into a typical 240V motor load.

    Info on Atco OG-style ballasts which are the most common in Australia - Here is Line Start Current at Power Factor of 0.9 and Mains Input of 240V :

    400w AMERICAN lamp = 3.0 to 3.4 A

    400w EUROPEAN lamp = 2.4 to 2.8 A

    The "American" or "European" refers to the electrical characteristics of the lamp, not the country of origin.

    European lamps operate on Sodium gear and have 100V 4.6A arc tube

    American lamps operate on Mercury gear (+ an Ignitor) and have 135V 3.25A arc tube.

    American lamps can also operate on Contant Wattage gear, in which case the start current is only 1.2A (which is lower than the run current).

    Other brands & types of ballasts have different characteristics, but will be within about 10% of the Atco info above. Note that the Power Factor capacitor is important - without the capactitor (LPF) the start current will be doubled

    Cheers, John
