The ECM INDUSTRIES LLC 20-100 is a blue tap splice connector designed to create secure mid-wire branch connections without stripping the existing wire. Each connector accepts 18 to 14 AWG wire and is rated for up to 300 volts maximum, with a temperature rating of 221 degrees F (105 degrees C). These connectors use an insulation-displacement design that cuts installation time on low-voltage wiring runs. Electricians, HVAC technicians, and panel installers reach for this type of connector when tapping into an existing circuit without breaking continuity. The pack includes 5 connectors, suitable for small service jobs or stocking a service van.
Tap splice connectors like the 20-100 are used in residential and light commercial wiring applications where a branch connection must be made to an existing wire run. Common install scenarios include thermostat wiring, control circuit taps, low-voltage lighting branches, and accessory connections on HVAC equipment. The blue color coding corresponds to the 18 to 14 AWG wire range, helping technicians select the correct connector size at a glance on the job.
Designed for use with 18 to 14 AWG insulated copper wire in low-voltage control and branch wiring applications.
Installation is performed by licensed electricians or qualified HVAC technicians following applicable NEC guidelines for branch circuit taps. De-energize the circuit before installing any splice connector. Seat the connector fully with the appropriate crimping or snap-close tool to ensure proper insulation displacement and a secure electrical contact. Do not exceed the 300-volt or 105 degrees C ratings.
