Extech Instruments 480400 Phase Sequence Tester

Extech Instruments 480400 Phase Sequence Tester

Q: Will this work on 4/0 wire?

Yes I personally used it on 750MCM which is 5 times the diameter of 4/0. This is a great phase rotation meter.

Q: Does it work on 480-V delta and wye systems?

Yes. It has worked perfectly on all systems and all voltages up to and including 480 for us. Excellent tool and much safer.

Q: Will this work on the output of a VFD?

It should as long as the VFD is running (being commanded to go a direction at 50-60 HZ)

Q: Can this be used on single phase 240 volt service?

Hi, phase sequence is only used to determine the correct phasing of the 3 phase supply. You need not use this device for single phase at all. You only need a volt meter to ensure that the supply is in order in terms of L N E.
