Type B vs Type E Plugs: Voltage & Amperage Differences & Compatibility

Type B is a 3-pin, grounded plug rated 15A at 100-127V, while Type E is a 2-pin, grounded plug rated 16A at 220-240V. The two differ mainly in voltage, amperage and pin design, which is what decides compatibility — whether a Type B plug fits a Type E socket, and vice versa. Also see type I vs type J plug.

Key Differences Between Type B and Type E

Here's how Type B and Type E compare, point by point.

  • Grounding: Both Type B and Type E are grounded.
  • Pin Size and Shape: Type B: Two flat parallel pins plus round grounding pin (4.8mm diameter). Type E: Two round pins (4.8mm diameter) plus hole for socket grounding pin.
  • Application: Type B is typically used for heavy-duty appliances such as hair dryers, kettles, and heaters. Type E is typically used for heavy-duty appliances such as hair dryers, kettles, and heaters.

Type B and Type E Compatibility

Type B in Type E Sockets: Generally no. A Type B plug (Two flat parallel pins plus round grounding pin (4.8mm diameter)) does not fit a Type E socket (Two round pins (4.8mm diameter) plus hole for socket grounding pin) without a travel adapter.

Type E in Type B Sockets: Generally no. A Type E plug (Two round pins (4.8mm diameter) plus hole for socket grounding pin) does not fit a Type B socket (Two flat parallel pins plus round grounding pin (4.8mm diameter)) without a travel adapter. Also see is type F compatible with type L.

Does a Type B plug fit into a Type E socket?

Generally no. A Type B plug (Two flat parallel pins plus round grounding pin (4.8mm diameter)) does not fit a Type E socket (Two round pins (4.8mm diameter) plus hole for socket grounding pin) without a travel adapter. Also see type G vs type K plug.

Are Type B and Type E plugs the same?

No. Type B follows the NEMA 5-15 standard and Type E follows CEE 7/5 — they differ in pin count, voltage rating.

Which countries use Type B and Type E plugs?

Type B plugs are used in 54 countries, including American Samoa, Anguilla, Antigua and Barbuda, Aruba, Azores. Type E plugs are used in 44 countries, including Belgium, Benin, Burkina Faso, Burundi, Cameroon. 1 countries use both, including Laos.

How can you tell a Type B plug from a Type E plug?

A Type B plug has two flat parallel pins plus round grounding pin (4.8mm diameter), and is grounded. A Type E plug has two round pins (4.8mm diameter) plus hole for socket grounding pin, and is grounded. The quickest tell is pin count: 3 vs 2.
