This plug and receptacle are technically known as NEMA 5-15 (North American 15 A/125 V grounded)
The type B plug has two flat parallel blades like type A, but has a round ground or earth pin. It is rated for 15 amperes at 125 volts. The ground pin is longer than the live and neutral blades, so the device is grounded before the power is connected. The neutral blade in the Type B socket is wider than the live one to prevent polarized Type A plugs being inserted incorrectly. Type B plugs often have both pins narrow since the ground pin enforces polarity.
Looking directly at a type B outlet with the ground at the bottom, the neutral slot is on the left, and the live slot is on the right. They may be installed with the ground at the top or on either side. In new residential construction since about 1992, a 20-amp receptacle with a T-slot for the neutral blade allows either 15-ampere parallel blade plugs or 20-ampere plugs to be used.
Japan also uses a Type B plug similar to the North American one. However, it is less common than its Type A equivalent.
