Questions about this size

What breaker can 4/0-4/0-4/0-2/0 URD Aluminum Cable go on?
Its ampacity is 180 A (75 C column of NEC Table 310.16). The breaker can be that size, or the next standard size up where NEC 240.4(B) allows it. Derate first for more than three current-carrying conductors or high ambient heat.
How far can I run it before voltage drop is a problem?
At 180 A on a 240 V single phase circuit, about 195 ft one way keeps the drop at 3 percent, the figure an informational note to NEC 210.19(A) suggests for branch circuits. Try other loads in the voltage drop calculator.
Can it be buried directly in the ground?
Yes. It is rated for direct burial; the minimum cover is in NEC Table 300.5 (24 in. for direct burial under the general condition).
Can I buy it by the foot?
Yes, cut to length in whole feet from 50 ft, or on 500 ft spools. Cut wire is final sale; uncut spools can be returned within 30 days.
