Electrical plug and power cord Standards in Mexico

Mexico primarily uses the following electrical standards for plugs, sockets, and power supply:

1. Voltage: 127 V (volts)
   • Some regions, particularly near the U.S. border, may also use 120 V.
   • Large appliances (e.g., air conditioners, washing machines) sometimes operate at 220 V.
2. Frequency: 60 Hz (hertz)
3. Plug Types:
   • Type A: Two flat parallel pins (ungrounded), compatible with North American outlets.
   • Type B: Two flat parallel pins + a round grounding pin (grounded), also common in North America.
4. Socket Compatibility:
   • Mexican outlets generally accept both Type A and Type B plugs.
   • Devices with Type B plugs can be used in Type A outlets if the grounding pin is not required.
5. Standards:
   • Mexico follows the NOM (Norma Oficial Mexicana) standards for electrical safety. For example, NOM-001-SEDE specifies electrical installations.
6. Adapters and Converters:
   • Travelers from regions using 220–240 V (e.g., Europe, Asia) may need voltage converters for non-dual-voltage devices.
   • Devices from the U.S., Canada, or Japan (110–120 V) typically work without converters, but checking labels is advised.

Key Notes:

• Always verify your device’s voltage range (e.g., “Input: 100–240 V”) to avoid damage.
• Universal travel adapters with Type A/B support are widely available in Mexico.
