Buchanan WT2-B Twist-On Connectors

The Buchanan WT2-B twist-on wire connectors join copper conductors in residential and light commercial wiring. Each blue polypropylene shell accepts solid or stranded wire from 22 AWG to 14 AWG. A pack of 500 pieces supports electricians and maintenance teams handling high-volume terminations.

Thermals and electrical ratings

The connectors carry a maximum operating temperature of 221 degrees F and a 300 V rating. Zinc-plated steel springs maintain contact pressure without a separate torque tool. UL 94 V-2 flammability rating and CSA certification confirm compliance with standard safety requirements.

Installation fit and capacity

Minimum combination starts at three 20 AWG wires; maximum combination reaches three 16 AWG wires with up to five conductors per connector. The 0.70 inch length fits inside standard junction boxes. Steel springs and polypropylene insulation require no fill material, keeping the termination compact for crowded enclosures.

Questions about this item

How do I install the Buchanan WT2-B twist-on connector and what step is often missed?

Strip each copper conductor to the correct length, insert up to five wires sized 22 to 14 AWG, then twist the connector clockwise until the steel-zinc contact grips firmly. The step often missed is verifying that no bare wire remains exposed outside the polypropylene shell.

What maintenance or replacement will the WT2-B connector need over time?

The connector itself is maintenance-free, but inspect the joint if the circuit sees vibration or temperatures approaching the 221 °F rating; replace the unit if the polypropylene insulation shows cracking, discoloration, or if the spring contact loses tension.

What limit appears first when the WT2-B connector runs continuously at high load?

The 221 °F maximum operating temperature is the first limit reached under sustained current; exceeding it can degrade the polypropylene insulation and the V-2 flammability rating before the 300 V voltage rating becomes a concern.
