How many amps required to run a single phase 4 ton air conditioner?
Every piece of equipment is different depending on the age and size of the equipment. Older machines usually require more electricity than a comparable unit that is new of the same size. Example; I had a 1and 1/2 ton condensing unit that was here when I bought my house which required a minimum circuit ampacity of 2pole 30amp breaker. I purchased a new 3 ton unit that only requires a 2pole 25amp breaker and when in use the compressor is only pulling about 17 amps by my clamp on amp meters reading.( That is on each leg) So the newer equipment is much more efficient than older equipment and a lot less costly to

Why is Rittinger constant dimensionless?
The Rittinger constant is dimensionless because it represents the energy required to reduce a unit mass of material from an infinitely large particle size to a specific particle size. Since it is a specific energy value, it does not have any units and is expressed as the work required per unit mass.
