ECN Forum Forums General Topics of the Trade General Discussion Area 50HZ vs 60HZ

I am stuck with 208V, 3 Phase, 4 wire WYE.

I do know that voltage and HZ is not what is needed but one of the strange things is that some of the units have been in service for 6+ months and are working fine, and some others are failing over a few days/weeks.

I sent in some pictures of the units, hope they get posted.

Thanks, Roger
