Frequently Asked Questions
Q: Are these brass terminal block connectors truly waterproof?
A: Yes! Each connector comes with a heat-shrink sleeve that, when applied with heat, forms a tight waterproof seal around the wire joint — protecting it from moisture, dust, and corrosion. This makes them well-suited for outdoor, automotive, and marine wiring applications.
Q: What wire sizes and current ratings are compatible with these connectors?
A: These brass terminal block wire connectors are available in 10A, 20A, and 60A current ratings at a rated voltage of 250V. Please select the appropriate rating based on your circuit's requirements to ensure a safe and reliable connection.
Q: How do I install the heat-shrink butt splice connectors?
A: Simply insert the stripped wire ends into each side of the terminal block (1-in / 1-out), secure the connection, then apply heat (using a heat gun or lighter) to the shrink sleeve until it contracts snugly around the joint. No special tools are required beyond a standard heat source.
Q: Can these connectors be used for both Round and Square style preferences?
A: Yes — these connectors are available in both Round and Square styles. You can select your preferred shape when ordering, making them flexible for various installation setups and enclosure types.
