What are NM connectors?
NM Connectors – Nonmetallic Cable and Portable Cord Fittings.
How do you connect NM cable connectors?
Simply push the NM cable through and it is grabbed firmly. Being plastic, they protect the cable from chafing, or cutting. I think they are great and worth the money. I highly recommend these.
What is the maximum number of NM cables in a connector?
Most NM-connectors are UL-approved for securing only one NM-cable to a panel box. But some are rated for two #14 or #12 cables, and we know of one 3/4” connector that is rated for three. Check the box for the number approved by the manufacturer, but it’s definitely not more than three.

How often should NM cable be supported?
every 4 ½ ft.
NM cable must be supported and secured every 4 ½ ft. and within 12 inches of every outlet box, junction box, cabinet, or fitting. Secure and support.
