## Questions & Answers

**Q: Will this work on 4/0 wire?**
A: 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?**
A: 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?**
A: 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?**
A: 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.
