We as a company install a lot of HID fittings
High Pressure Sodium, Metal Halide, Mercury Vapour, and some low pressure Sodium for car parks,
The thing that puzzels me is the loading and the current draw you are saying, it sounds as though that the installation is incorrect as the approxiamte loading on 230v ac with a loading of 2800watts @ 12.17 amps.
You getting a reading of 50 amps is rather to high, my advice is that you check the following;
cable type, size, and integrity (damage etc)
lamp type,
control gear (ballast, ignitor,capacitor)
wiring of control equipment
integrity of CB (is it suitable for this type of load)
if these all match then check the supply loading,
I am curious to know the outcome so please keep me posted.
