Neutral Point of Heater Bank

FornhamSpark
Hi,

I have an application to control a bank of resistive heating elements (52Kw) in a Star configuration from a Eurotherm Power Management unit to control heat output.

Is it standard practice to connect the Neutral Point to Neutral ?

    Sorry Geoff, I don't think that a lamp and a resistive heater element are comparable either.

    A lamp has a very different current/temperature/resistance characteristic to a big resistor, which is basically all most of these heating elements are.


    Apart from that, it's a bit of a mute point anyway because likely the Eurotherm unit will have in its instructions what is required, so you'll have to follow that otherwise it will throw a freaky fit.

    They are often SSR based.
