Connecting Aluminum and Copper Conductors

Copper (Cu) or aluminum (Al): For electrical cables, it’s not a question of faith, but usually an issue of price. Both have their advantages and disadvantages, but when they come together, things can get dicey. However, electricians don’t necessarily need a specialty Al/Cu connector for building installations. With WAGO Alu-Plus Contact Paste, they can connect aluminum and copper conductors using WAGO connectors – quickly, easily and reliably.
