How many nm cables does a clamp have?

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 many Romex cables can pass through a connector?

Can you run Romex exposed in garage?

When running Romex through garages, it is important that it is insulated to ensure that the wire doesn’t get damaged. As for the question of whether Romex can touch insulation or not, yes, it can.

Is MC cable better than Romex?

Safety: Compared to Romex, MC cable is safer to install due to its metallic sheath. This sheath helps protect against accidental shearing and penetration, reducing the risk for accidental wire exposure. Romex sheathing is easily penetrated or sheared, making it less safe unless run through protective conduit.
