Help ID-ing wire size-pic
This is buriable aluminum wire that goes to my doublewide I'm putting in..this is a piece of the wire that was in it but it's unmarked, I want to replace it exactly--150amps on the breaker. Home Depot couldn't tell me what it is! Size?

If the old cable was unmarked by code it could not have entered the mobile home. It would have had to be transitioned to different wire before entering. Be sure the cable you buy have each conductor marked as to type of wire. Be sure it is four wires. Be sure your mobile home panel has both a bonded ground bar and an isolated neutral bar. Be sure there is at least one ground rod and the water pipes if metal are bonded. Be sure all grounds and neutrals are on the correct bar. Be sure the panel in your MH is rated for at least 150 amps and has a 150 amp main breaker.

You would need some calipers to take a precise measurement of the diameter of the metal of the wire -- not the plastic insulation.
The wikipedia page has the relevant diameters in the leftmost columns inches and millimeters:
https://en.wikipedia.org/wiki/American_wire_gauge
The total ampacity depends on how and where the cable is installed once you find the AWG. For a 150A service it should be either #2/0 or #3/0 depending on some details and age.

Thanks, I'm going to take it to an electrical supply store and get it exact, the printing on the cable is unreadable, whatever printed it on the cable cut the words/numbers in half=unreadable...

There's only 4 ft attached to the box when it was with the previous owner (unknown), I bought it from a "mover' "as is" and this is what was used for the 150 amp service, just a piece of it that had been cut off.

I have to go 135' underground from the pole (200amps) to the trailer (150 amps),
