Patent ID: 8476786

Claim:
A system for coupling to conducting paths that include a sheath conducting path, a first conducting path, a second conducting path, and a third conducting path, the system comprising: a first control module configured for coupling to the first conducting path and for being in electrical series with a first well load coupled to the second conducting path; a second control module configured for coupling to the second conducting path and for being in electrical series with a second well load coupled to the first conducting path; a third control module configured for coupling to the first conducting path and for being in electrical series with a third well load coupled to the third conducting path; and a fourth control module configured for coupling to the first conducting path and for being in electrical series with a fourth well load coupled to the sheath conducting path, wherein the second control module, third control module, and fourth control module prevent leak current from flowing to the second well load, third well load, and fourth well load, respectively, when the first control module allows current to flow to the first well load.
