The 3M 7000133222 is a Performance Plus Wire Connector designed for use in residential and commercial electrical wiring applications. Known as the O/B+ connector, it combines a compact shell with an expanded wire range, accepting from two 22 AWG wires up to three 12 AWG solid wires or four 14 AWG wires. The improved spring mechanism bites wire quickly and with less hand effort than standard connectors. The small shell profile fits into tight junction boxes and enclosures, and the flexible skirt provides a barrier against contact with overstripped wire ends. Licensed electricians and electrical contractors are the primary installers.
This connector is suited for a wide range of residential and commercial wiring jobs where multiple wire gauges are encountered in a single service call or installation. The O/B+ is designed to replace orange, blue, and gray spring connector style connectors, as well as approximately 70 percent of yellow spring connector and wing style connectors. Sold in a 500-count jug, it is well-suited for stocking service vehicles or shop inventory where connector variety and volume are daily concerns. The broad wire range reduces the number of connector SKUs an electrician needs to carry on the job.
The O/B+ connector replaces orange, blue, and gray spring connector style connectors, as well as approximately 70 percent of yellow spring connector and wing style connectors across a wide range of general wiring applications.
Installation is performed by licensed electricians in accordance with applicable NEC requirements. De-energize the circuit at the breaker and verify with a voltage tester before making wire connections. Strip wire ends to the appropriate length per the connector manufacturer guidance and insert wires fully before engaging the spring. Do not exceed the stated wire range of the connector, as overfilling can result in an unreliable connection.
