RYB is identification of three phases by colour - Red, Yellow and Blue.
the comanies that use the ABC system.
That doesn't make any sense. Try re-phasing the question.

The ABC's are rudimentary :)
The Abc
Of the three conductors the combination is irrelevant except with respect to phasing and rotation. If the equipment requires proper phasing ( motors need to turn a specific direction), wire it up and "bump" a contactor. If the direction of rotation is not correct, swap 2 of the conductors. Do the swap at the lineside of the disconnect/ breaker, etc. In the case of an HVAC/R non-scroll compressor, rotation is not an issue. One exception would be if the control system were to use one phase to neutral. This should not be the case as you specified 4 wire three phase, which implies the fourth conductor by code, is a ground and control is provided by two of the three conductors providing control voltage. Check the schematic and/ or contact the manufacturer of the equip. lc
In a company name such as "ABC Corp," do not use a comma. However, use a comma in the formulation, "ABC, Inc."
Use what is called bell wire or thermostat wire.
Use the 4 wire if possible. You would only use a 3 wire for an old appliance.You shouldn't if possible. The 3 wire has no neutral wire as the 4 wire does. Som applications require the use of a 3 wire and some don't.

The ABC's
The recommended gauge of wire to use for a 12 or 14 gauge wire is typically 10 gauge wire.
