Steel Square-Cut Spring Winged & Non-Winged Fixed Spring Features Easy recognition of wire ranges with 5 distinct colors The different colors of electrical wire nuts (also called twist-on wire connectors) indicate the size and capacity of the connector, meaning the number and gauge of wires they can securely connect. Each color typically corresponds to a specific range of wire sizes and combinations. Here’s a general guide: Common Wire Nut Colors and Their Usage: Gray Typically used for very small wire connections. Works with 22 to 16 gauge (AWG) wires, ideal for low-voltage wiring. Blue: Used for small connections, often for light-duty applications. Suitable for 22 to 14 gauge wires. Orange: One of the most common for residential wiring. Can handle 18 to 14 gauge wi
