No neutral in Panel board for 3phase pumps that do not require a neutral

Dale Rogers

Hi all, on a recent EICR I have discovered a Panel board with no neutral but it is labelled for 3phase pumps only that do not require a neutral what are your thoughts on this matter?

    A 3-phase 4-wire system can be used to supply a 3-phase 3-wire portion of the installation. 

    It's purely a "nature of supply" issue.

    There is no requirement to distribute a neutral in a three-phase 3-wire system that is earthed at the star point (neutral) of the source.
