A/C Conductors could the face plate rating be wrong on this unit.
I used 10-3 according the face plate rating of the AC condenser. I also installed a surge suppression (homelite phase to natural 22K amps) in the panel. I also figured the locked rotor amp calculation just to be sure about the conductor size for the A/C condenser. 45 amp breaker also installed per the plate rating and my calculations. The factory and my calculation do match.
Here is the problem or is it a problem?
When this unit starts up. There is a slight dimming of lights in the home sometimes, I mean very sight dimming. I never saw that happen before. This is a new home install with a 40 space Square-D. Could there be a capacitor problem in the A/C unit? I did call the A/C Company; they came and checked out the unit and said ?unit is fine and running in top condition? they were not sure about the dimming somtimes.
Would using 8-3 conductors be better to take out this slight dimming of lights? I figured the motor must be pulling a lot of in-rush current at start-up All connections are on spot with my torque. might use my fluke equipment Monday. is this common with some Ac units ?
