      Q:How many 14/2 can I put in the 3/4" connector?

      Answer This Question

      A:  For 14/2 you need to use the 3/8" fitting- #90510. The 3/4" can be used with 12/3 or 8/3.

      by|Oct 5, 2022

        A:  I pulled four 12 gauge wires through the connector. If you are pulling 14-2 with ground I would say one. I would recommend buying individual wires and pull that. Easier and cheaper .

                  Great clamp because they can be used for one wire or multiples due to the upper clamp having A bump. It is able to grip the wires without crushing them.

                  I just bought a bag of 5 of these at my local Home Depot. Part# 20512. I am doing an electrical project and the knockout on the junction box is 3/4". These connectors are actually 7/8" and do not fit. The bag says 3/4", but don't fall for it!
