Answer for USA, Canada and countries running a 60 Hz supply service.
500 mcm wire is a stranded wire with the equivalent of 500,000 circular mils in cross-sectional area.
A circular mil is a circle with a diameter of 1 mil, or 1/1000th of an inch.
500 kcmil means the same thing.
In common practice this size conductor is capable of handling 400 amps.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

A 350 MCM copper conductor with an insulation rating of 90 degree C is rated at 350 amps.
600amps
500 mcm (or 500kcmil) conductors are used for 400 amp 480v single phase or 3 phase systems. The wire AND THE TERMINALS must be rated for 90o Celsius.
A 750 MCM copper conductor with an insulation factor of 90 degrees C is rated at 500 amps.
A 500 MCM wire with an insulation factor of 90 degrees C is rated at 430. Most 400 amp services will use parallel wires on each leg to feed the circuit. A 3/0 wire with an insulation factor of 75 and 90 degrees C is rated at 200 and 225 amps respectively. The insulation rating of these conductors will be 600 volts.
500 MCM can carry 380 Amps at 75 degrees C.
A 350 MCM copper conductor with an insulation rating of 90 degree C is rated at 350 amps.
600amps
500 mcm
It depends on a lot of factors. Generally speaking, if the insulation is THHN then the rating is 350 amps. If the insulation is THWN then the rating is 310 amps. The ampere rating for wire depends on the temperature of the environment it will be used in, the insulation rating and the number of circuits installed in a conduit. There are also other factors to consider... like voltage drop in long runs.

4 sets of 750 mcm aluminum. Or four parallel runs of 600 MCM copper.
500 mcm (or 500kcmil) conductors are used for 400 amp 480v single phase or 3 phase systems. The wire AND THE TERMINALS must be rated for 90o Celsius.
yeah sure ill have 1
