NEMA-1-15P-plugs-old-new-electric-toy.jpg

Summary

Description
English: Four NEMA 1–15P electric plugs. The right middle plug is newer than the left middle plug and has a wider face near the prongs. This design may reduce the risk of electric shock. The rightmost plug is for a model railroad power pack and has a noticeably wide face; electrically-operated toys sold in the US are subject to regulations that include a minimum size for the plug face. Early electric plugs (leftmost) also had this wider face. ( US 16 CFR §§ 1505.5(e)(3) .)
