The New Macey 300 Amp Phase Rotation Plug is engineered to improve safety and efficiency when testing high-current circuits in underground mining environments. Designed for use on 660V, 1100V and 3300V systems, it provides reliable phase sequence indication before equipment is energised.

Traditional phase testing methods can expose operators to awkward working positions or unclear indication points. The New Macey design positions the LED display panel for improved visibility, allowing operators to confirm phase rotation safely and confidently without unnecessary strain.

This product enhances safety by enabling high-voltage phase confirmation without energising equipment, reducing risk while supporting efficient commissioning and maintenance procedures underground.
