Reading 300 volts at condenser fan

WebJun 30, 2016 · Since NEMA’s +/- 10% tolerance for 230 volt rating would extend down to 207 volts (230 x .90 =207), that appears safe. The problem is that the actual voltage from a 208 volt source could dip well below 207 volts. In addition, ordering a motor rated 480 volts for use on a 480 volt circuit, while allowable, isn’t recommended. WebFeb 13, 2024 · In a three-wire connection, the white/yellow wire connects the condenser fan motor to one side of power on the contactor (the terminal side doesn’t matter). It’s also jumped to one side of the fan capacitor. The connection occurs at T1. The black wire connects the condenser fan motor to the other side of power on the contactor (T2).

WebMar 20, 2014 · Typically, motors have an operating tolerance of 10%± of the rated voltage on the nameplate (consult your manual). This means that a motor designed to run on 230V can run at 208V (or 240V). Motors should not run outside their designated voltage range, doing so will damage your motor and or equipment. WebOct 1, 2007 · By installing a VFD on a condenser, fans now can run at a lower speed, reducing startup noise. Also, the whine that is produced as fans start and climb rapidly to full speed also is reduced because the fans are ramped up to the required speed gradually.
