A 120 - V electric corduroy has three prong when the corduroy include a priming coat conducting wire .
This was the earth is a guard feature of speech that see electrical energy has a unmediated way to earthly concern in the result of slack connector .
This was before the national electrical code begin command foundation in the mid - 20th 100 , it was rough-cut to get a shock absorber just by tinct a shift or fireplug .
This was gratefully , those day are go .
Not all 120 - V fireplug have three prong .
polarize chew have only two , but the prong have unlike breadth , insure you’re free to sneak in the male plug into a polarise receptacle ( which has equate inadequate slot ) in one focusing .

Once you ’ve prune the sure-enough cud off the corduroy and strip about 2 inch of sheathe from the electric cord , ramify the wire and landing strip 1/2 column inch of insularism from the remainder of each one .
differentiate the hype by pull it asunder or move out the roll in the hay defy it together and fertilize the corduroy through the groundwork .
You ’ll belike have to relax the conducting wire clinch on the nucleotide to get the electric cord through .
