Unexpected high current on 3 ph induction hob.

hertzal123
Have to run a supply for a 3ph 14kw induction hob.Without considering power factor,

I calculated 14000/3 divided by 230v to give 20.28A/phase.Looking at the data sheet

the rated current is 38.9A/phase,indicating a pf of 0.52.Is this normal for this type of kit?

Thanks for any advice,

                              Regards,Hz

    You'll sometimes find a switch or jumper inside things with compressors such as window a/c units to switch between 208 and 240.  277 single phase is almost never used for loads on its own with the exception of lights. (many light fixtures such as emergency lights come with a multitapped transformer). When run off 120v, the 277v tail is capable of giving you a fairly nasty whack if you don't have it capped off!
