What wire size should you use for 600 amps?

Answer 1

The wire size for 600 amps on a single wire 1250 MCM. A 1250 MCM copper conductor is rated for 645 amps with an insulation rating of 90 degrees C. This size of wire is too large to handle easily when it comes to the terminations. A service requiring 600 amps is usually paralleled or tripled which reduces the wire size which makes the wire much easier to handle. For a parallel service two 350 MCM cables are used and for a triple parallel run three 2/0 conductors are used. These conductors all have an insulation rating of 90 degrees C.

Answer 2

For 600 amps, you would typically need at least a 250 MCM wire size to safely handle the current without overheating. It's recommended to consult with a professional electrician to determine the specific wire size needed based on the application and local electrical codes.

Answer 3

A 1250 MCM copper wire with an insulation factor of 90 degrees C is rated at 645 amps.

A 1500 MCM copper wire with an insulation factor of 75 degrees C is rated at 625 amps.

Answer 4

It depends on a few things:

1. What type of conductor e.g aluminium, copper etc

2. Length of conductor required

3. Aloowable voltage drop. usually 4%
