Martindales PC15250 continuity indicator will quickly and simply prove continuity of all three lines (or identify which are faulty) and shows the sequence of phase rotation.
It gives a fast, effective method of identifying worn or unmarked cables and ensures 3-phase outlets and machines are wired correctly.
The retractable GS38 probe shields give a choice between long exposed tips for reaching inaccessible contacts and safer, shorter lengths for increased safety.
