[fxdave]

Nothing wrong with that, except that it is aluminum wire and needs to be connected with due regard for AL-CU interactions if copper wires or outlets are used. It is suitable for direct burial or use in raceways and is normally at least 2 gauge, so plenty large for a long run at 50A/240V.

Be sure to use antioxidant compound at all connections.

Annually check torque of connections as they tend to loosen.

If you want a true 50 amp service, make sure you run two hots, a insulated ground and a insulated neutral.

# 6 copper is your best bet for that distance. You can buy cable that has what you need. Three strands of # 6 with one strand of # 8 for the ground.

Also, make sure that your neutral and ground run all the way back to the Main panel where they are bonded together.

No other grounds are acceptable.

If you are planning to keep a full load on that wire, you might think about upgrading to # 4.
