m = 1000 c = 100 d = 500 MCMD doesn't make sense MCM = 1900 MD = 1500 CM = 900 so it would be MCM + D = 1900 + 500 = 2400, but that would be written MMCD

MCM is 1900
MCM
MCM = 1900
MCM stands for 1000's circular mils. Broken down MCM means 1000's (M) of (C)ircular (M)ils. A Circular Mil means the area of a circle 1/1000 inch in diameter. 1000 MCM conductors are 1 inch in diameter.
The amp rating of a 500 MCM (thousand circular mil) cable can vary depending on the insulation type and installation conditions. Generally, a rough estimate for a 500 MCM cable with THHN insulation in a typical installation would be around 380-400 amps. However, it is recommended to consult the manufacturer's specifications or a qualified electrician to determine the exact ampacity for a specific application.
For a 4000 amp service, a grounding system with at least 2/0 AWG copper or 4/0 AWG aluminum wire is typically required. The exact size of the grounding system will depend on factors such as the type of soil, moisture levels, and fault current calculations. It is recommended to consult with a licensed electrician or engineer to determine the specific size needed for your installation.
The diameter of an insulated 750 MCM copper wire is 1.25 inches. The insulated 750 MCM copper wiring has 61 strands and has a weight of 2.7 pounds per foot.
500 mcm
1 MCM means 1000 circular mils, and a circular mil is the area of a circle with diameter 1 mil ( that is 1/1000 of one inch). In metric terms, 1 MCM = 0.5067 sq mm
The required size of a conduit raceway for a 3-5000 mcm wire is 300 kcmil. It maximizes the limits on the wire fill for raceways.

A 750 MCM copper conductor with an insulation factor of 90 degrees C is rated at 500 amps.
About 4.5 acres for a 500-foot diameter circle.
A 228 sq mm conductor equates to 450 MCM. A conductor of 450 MCM is not a standard AWG wire size. A standard 400 MCM will carry 380 amps. A standard 500 MCM will carry 430 amps. Difference between 400 and 500 MCM amperage's is 50 amps. Transposing between the two amperage's of 50 amps will be 380 + 25 = 405 or 430 - 25 = 405 amps. This is a very rough calculated answer for the question.
