ECN Forum Forums General Topics of the Trade General Discussion Area 230 Volt machinery on 208 volts

Hello All,

I'm doing a major machine shop move.The old building was a 240 volt service,the new one is 208 volts.

I have four older CNC machines designed to run on 230 Volts.I'm right on the 10% voltage threshold (207 volts)

According to the Manufactuer's of the machines 208 is ok.

I'm wondering what the long term effects will have on the motors and what experience you guys have encountered with this situation.

Thanks in advance
