When you have a 208 3 phase panel why across two legs do you only get 210v but across each phase you get 122 V. So the problem is 240 V Clothes dryer is not coming to full heat because of the low-voltage.
Please fill out your profile.Yes 25 years never ran into this problem yet.
Everything always worked fine I’ve never had this problem before but for some reason the dryer is not drying the clothes and the manufacturer is telling me because the voltage is not high enough.Forget about trying to boost that voltage. 120/208 is as common as dirt and most 240V appliances are happy to run on 208. I wire restaurants and most appliances are 240 running on 208. Where have you been for 25 years that you have never worked on 3 phase?
