Voltage drop at 100 ft	5.24 V, 2.2 percent at 85 A and 240 V single phase
Run length for 3 percent drop	About 135 ft one way at 85 A and 240 V
Outside diameter	0.352 in

What breaker can 4 AWG USE-2/RHH/RHW-2 Stranded Copper Wire go on?: Its ampacity is 85 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. With 60 C rated terminals (the NEC 110.14(C) default at 100 A or less unless the equipment is marked 75 C) it is 70 A.
How far can I run it before voltage drop is a problem?: At 85 A on a 240 V single phase circuit, about 135 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 25 ft, or on 500 ft spools. Cut wire is final sale; uncut spools can be returned within 30 days.
