Electrical tape is an insulating tape used to protect, bundle, and identify electrical wires and connections.

Electrical tape is a pressure-sensitive tape designed to insulate electrical wires and connections. It helps prevent short circuits, protects conductors from moisture and abrasion, and provides an additional layer of safety around electrical splices and terminations.

In construction and electrical work, electrical tape is commonly made from vinyl, rubber, or specialized synthetic materials. Different colors are used for phase identification, grounding, and circuit marking, allowing electricians to quickly identify wiring systems. Electrical tape is often used alongside wire nuts, connectors, and heat-shrink products—not as a primary means of connection.

Proper application of electrical tape is important for durability and code compliance. Tape must be rated for the voltage, temperature, and environment in which it is used. While electrical tape is a useful accessory, building codes typically prohibit using tape alone as a permanent wire connection.

Electricians often carry multiple colors of electrical tape not just for safety—but also to mark circuits quickly during troubleshooting.
