That's 277 volts of alternating current.
This is typically one phase of a 480v 3 phase system. Don't worry that 3 x 277 adds up to more than 480v.
A 277v line is typically one phase of a 480v 3 phase system.
It depends on what 277 volt device you are trying to connect.
v = volts a = alternating c = current vac is what the lights and appliances in your house use. Your TV uses 120VAC. 120vac is the accepted standard of electric current commonly used through out the U>S>. Vac speaks of ac or alternating current voltage.
Yes, generally, all other things being the same. By all other things I mean the capacitance, the type of capacitor for the application, etc.
vac stands for AC voltage
The difference is that the 440 vac capacitor has a 70 volt-amp-current higher output than the 370. Capacitors must always be replaced with the same size micro-farads or you'll damage the device, such as a motor. The vac rating can be changed with a capacitor with a higher rating but not lower. Example: 15mfd at 370vac can be replaced by a 15mfd at 440vac, but not the opposite.

In WYE 480 VAC each leg to neutral is equal to 277 volts. 480 / 1.73 (sq root of 3) = 277.
empty
The answer to this is country-specific. In the United States: Residential 120 VAC. Commercial also uses 277 VAC Elsewhere in the world: 220 volts to 260 volts, most frequently 230-240 volts AC.
115 volts alternating current
Some meanings for VAC could be short for vacation or vacuum. VAC can also mean Veteran affairs Canada or even Variety artists club or virtual audio cable.
The latin root vac means empty
7% of 277 = 7% * 277 = 0.07 * 277 = 19.39
125% of 277 = 125% * 277 = 1.25 * 277 = 346.25
48% of 277= 48% * 277= 0.48 * 277= 132.96
11.9% of 277= 11.9% * 277= 0.119 * 277= 32.963
You can convert 24 vac to 5 vac with a transformer with windings in the turns ratio of 24 to 5.
