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.

What size wire is required for 325 amp service?
A 350 MCM copper conductor with an insulation rating of 90 degree C is rated at 350 amps.
What is the amperage rating of 800 MCM Copper wire?
600amps
Can you run 500mcm to feed 480 volt 400 amp service?
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.
What gauge is 500 amp cable?
A 750 MCM copper conductor with an insulation factor of 90 degrees C is rated at 500 amps.
What size wire is needed for 400 amp 480 volt service?
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.
What is the amp rating of 500mcm?
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.
What size wire is required for 325 amp service?
A 350 MCM copper conductor with an insulation rating of 90 degree C is rated at 350 amps.
What is the amperage rating of 800 MCM Copper wire?
600amps
What is the amperage rating of 500 MCM copper conductor?
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.
What size wire is needed for 1600 amp service?
A 1600 amp service typically requires 500 kcmil copper wire or 750 kcmil aluminum wire. It's important to consult with a qualified electrician to determine the exact size and type of wire needed for your specific installation to ensure safety and compliance with local electrical codes.
Can you run 500mcm to feed 480 volt 400 amp service?
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 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.
400 amp service what size wire?
For a 400 amp service, you would typically use 500 kcmil copper wire or 600 kcmil aluminum wire for the main service conductors. It's important to consult with a licensed electrician and check local electrical codes to ensure the correct wire size is used for your specific installation.
