Question

Prove or disprove the solution proposed by the homeowner. Given: A homeowner wants to supply power to a storage shed six hundred feet from the exterior meteripower panel. Loads consist of 120V lighting only. To save money, the homeowner would like to purchase and install only the hot wire. To complete the circuit, the homeowner proposes to drive a 10' long, %" ground rod at the storage shed and connect the neutral conductors from the lighting loads to it Assume - No additional assumptions Find Will the lights come on and produce light? Provide reason(s) supporting your answer. Solution:

Explanation / Answer

The standard specifications for Grounding Rods are generally that the rod must be at least 8' long and the diameter of rod should not be less than 5/8 " .Here the homeowner is using a 10' rod and 3/4 " in diameter.So the rod is meeting the required standards.

As far as flow of power is concerned,it just requires a potential difference to exist between the terminals of a load.The best example is the Electric traction system,which uses only one conductor to power the train and the earth and rails act as return conductor.

So the Lighting loads will glow in this case.Since the loads are lighting loads only,safety will not matter.But in loads with metallic bodies,this must be avoided at all costs,because it may lead to electroluction of personnel working on the load.
