The LEDCO Outdoor Marette with Silicone uses a dielectric silicone compound that fully encapsulates the wire splice inside the connector. This silicone sealant prevents moisture ingress at the connection point, which is critical for maintaining electrical integrity in outdoor and wet-location applications. Unlike standard indoor wire nuts, this connector is specifically engineered to resist the corrosion and oxidation that occur when bare copper is exposed to water or high humidity over time.

This connector carries full cUL and CSA certification, confirming it has been tested and approved for use in Canadian electrical installations. It is rated for wet and damp locations, making it suitable for use in outdoor junction boxes, underground conduit access points, and other exterior wiring scenarios where moisture exposure is unavoidable. Using certified connectors is not only a best practice — it is required by the Canadian Electrical Code for compliant installations.

From a thermal management standpoint, the silicone filling helps dissipate heat generated at the wire junction while simultaneously maintaining a secure mechanical and electrical bond. This reduces the risk of hot spots and loose connections that can develop over time in outdoor environments subject to freeze-thaw cycles and temperature extremes typical across Canada's diverse climate zones.

Installation is straightforward — simply strip the wire ends to the recommended length, insert them into the connector, and twist until secure. The silicone sealant automatically surrounds the splice, eliminating the need for additional waterproofing tape or secondary sealants. This outdoor Marette is compatible with a variety of standard residential wire sizes, making it a practical and code-compliant solution for connecting wiring on LED landscape lights, exterior wall fixtures, post lights, and any other outdoor lighting or electrical project around your home.
