Hi, I have a MCCB distribution panel (Schneider) and the circuits designed were for three phase circuits, however we have seen that the actual supplies needed will be single phase. Ive tried to obtain SP MCCB's to change these, however, apparently single phase versions aren't available in the UK. So, is it ok to use TP MCCB's or is this a contravention to the regs? Is it bad practice?
