This small device is generally called a terminal block or connector, more specifically a copper-aluminum transition terminal block, copper-aluminum transition clamp, or copper-aluminum transition connector.
It can connect both copper and aluminum wires, but do not twist them directly together.
Why use a transition piece?
Direct contact between copper and aluminum can easily lead to electrochemical corrosion, which over time can cause poor contact, overheating, and in severe cases, a fire risk.
Therefore, specialized copper-aluminum transition fittings should be used for connection to ensure greater safety and reliability.
You can find connectors for connecting wires by using names like these.
- Copper-aluminum transition terminal block.
- Copper-aluminum transition clamp.
- Copper-aluminum transition connector.
- Copper-aluminum lug.
Selection Recommendations
- For low-current, thin-wire household use: copper-aluminum transition terminals are commonly used.
- A more standardized approach: Choose products clearly labeled as suitable for copper/aluminum connections.
- Not recommended: Simply twisting the wires together and wrapping them with tape.
