A green wire can connect only to another green wire and should never connect to any other color wire. Strip or Wire Earthing: In this method of earthing, strip electrodes of cross-section not less than 25mm x 1.6mm (1in x 0.06in) is buried in a horizontal trenches of a minimum depth of 0.5m. Recent code additions now call for grounding in these electrical fixtures. Electric dog fences usually come with 20-gauge (thinnest), 18-gauge, 16-gauge, or 14-gauge (thickest) wire.
