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 ?

    Also if they're electronically (e.g. thyristor) controlled, you might find that a N connection is necessary even for normal operation - as the altered waveforms might not quite sum to zero in the way that a nice sine wave does.
