Tags: See more , See less 8 Answer Add Tags Answer Interview Answer 2 Answers ▲ 0 ▼ any1 know an answer to this one. is abit though? Anonymous on Nov 17, 2010 ▲ 1 ▼ It's a trick question that should take you one second to answer. Power consumption is in watts/watt hrs etc. The voltage required is constant and is either 120V/480V.Power consumption in watts on the other hand will depend on the type of rig, how deep they are drilling (which determines horsepower/torque blah blah blah). engr guy on Feb 14, 2012 Add Answers or Comments To comment on this, Sign In or Sign Up.
