(1)Based on a 10 min. period.

(2)Input voltage must be within ±10% of rated value.

(3)For 1 phase use on 208 or 230 VAC input with output usage above 175A/60% or 200A/35%, the #10 input line cord supplied with the unit should be changed to a

#8 or larger conductor cord.

(†) 200 & 208VAC input may not meet NEMA/IEC specifications at 250 Amps.
