Wire Connectors 20-Pack

Use UL‑listed gel‑filled nuts, heat‑shrink butt splices, or sealed lever connectors designed for wet locations and direct burial.

Yes—gel seals exclude moisture and oxygen, preventing corrosion. Standard indoor nuts are not suitable outdoors.

Use heat‑shrink butt splices for inline joins and crimp lugs at terminal bars. Choose tinned copper with adhesive‑lined shrink for sealing.

Strip to clean copper, use the right crimp tool/torque, and tug‑test each conductor. Seal immediately to prevent oxidation.

Yes—connections placed in soil must be listed for direct burial/wet locations. Use junction boxes where multiple runs converge.

Use connectors rated for mixed gauges and strand types, or step down through a terminal block in a junction box to keep clamping secure.

Some connectors are single‑use. Reusing can damage springs or seals; inspect carefully and replace if in doubt.

Keep connections above standing water lines, use gel‑filled devices, and add drip loops. Avoid sprinkler spray where possible.

Poor splices create resistance and voltage drop, causing dimming or early LED failure. Quality connectors maintain consistent voltage.

Open boxes and test a sample of splices seasonally. Re‑terminate any greened or heat‑stressed copper and refresh seals.
