Commando Plugs Explained: Blue vs Red
If you're looking at portable EV chargers, you've probably come across Commando plugs.
These industrial plugs are commonly used in workshops, campsites, commercial premises and agricultural settings because they're durable, weather-resistant and designed to handle higher electrical loads than standard household sockets.
This guide explains the differences between Blue & Red Commando plugs and helps you understand which type is suitable for your charging setup.
What Is a Commando Plug?
A Commando plug is a heavy-duty industrial connector designed for safe power delivery in demanding environments.
Compared to a standard 3-pin plug, Commando plugs offer:
- Higher power capacity
- Improved durability
- Better weather resistance
- More secure connections
This makes them ideal for EV charging applications.
Blue Commando Plugs
Blue Commando plugs are the most common type used for EV charging.
Key Features
- Single-phase power
- Available in 16A and 32A versions
- Commonly found at campsites, marinas and workshops
Typical Uses
For many EV owners, a Blue Commando socket provides a faster and more robust charging solution than a standard household plug.
Red Commando Plugs
Red Commando plugs are used for three-phase power supplies.
Key Features
- Three-phase electricity
- Available in 16A, 32A and higher ratings
- Higher power capability
Typical Uses
Where three-phase power is available, Red Commando chargers can support significantly faster charging than standard single-phase connections.
Single-Phase vs Three-Phase Power
Single-Phase (Blue)
- Most UK homes
- Common for residential charging
- Suitable for most EV drivers
Three-Phase (Red)
- Commercial and industrial properties

- Supports faster charging where compatible
If you're unsure which supply you have, a qualified electrician can confirm your installation.
Which Commando Plug Do I Need?
The correct plug depends entirely on the socket available at your location.
Before purchasing a charger, check:
- Socket colour
- Amp rating (16A or 32A)
- Single-phase or three-phase supply
Matching your charger to the correct socket ensures safe and reliable charging.
