Abstract
The present disclosure introduces apparatus and related methods pertaining to a first electrical power cable, a second electrical power cable, and a set of breakers. The first and second electrical power cables each extend a variable distance between a static system at a wellsite and a movable system at the wellsite. The breakers are operable to select either of the first and second electrical power cables to couple electrical power from a stationary electrical power source at the static system to a load at the movable system.
