The ECM INDUSTRIES LLC 10-100 is an insulated, solderless tap splice connector sold in a 25-pack. This type of connector allows a technician to tap into an existing wire run without cutting or interrupting the main conductor. It clamps onto the wire mechanically, displacing the insulation to make contact, which eliminates the need for soldering or heat shrink in most applications. Rated for 18 to 14 AWG wire, it suits a wide range of low-voltage control wiring tasks found in HVAC, electrical, and related trade work. The insulated housing provides protection at the splice point after installation.
These tap splice connectors are suited for residential and light commercial applications where a branch connection must be made to an existing wire without breaking the circuit. Common use cases include adding a secondary device to a thermostat wire run, splicing into control wiring inside an air handler or furnace cabinet, and similar low-voltage branch connections. The clamp-style design makes them practical for use in tight spaces where a traditional splice would be difficult to execute cleanly.
Designed as an OEM-style tap splice connector suitable for insulated wire in the 18 to 14 AWG range, as commonly found in residential and light commercial control wiring applications.
Tap splice connectors of this type are typically installed by licensed electricians or HVAC technicians working on low-voltage control circuits. Always de-energize the circuit before making any splice connection and verify the lock-out tag-out procedure is followed per site requirements. Use the correct plier or crimping tool specified for insulation displacement connectors to ensure full seating of the contact. Do not exceed the rated wire gauge range, as undersized or oversized conductors may result in a poor or unsafe connection.
