Under what set of circumstances would the 'other' box be ticked in the section of a certificate headed 'Number and Type of Live Conductors'? Does this have to be specified on any other part pf the paperwork?

The old "twin phase" was common in churches a long time ago, one phase was used for power and lighting while the other was solely for the electric heating due it being tubular heaters under all the pews.

Tick.
