Customer Question

Can I use Black 6-3 Romex NM-B W/G Wire to provide power from an interior subpanel to a SPA GFCI disconnect?
It will be run under the house attached to the joists and the GFCI will be mounted on the outside wall. From there we will run 6AWG THHN in conduit to the spa.

What is the best way to hang the 6awg 3 w/g NM romex to the joist? Staple? How large does it need to be if it is...
Expert:  Kevin replied 1 year ago.

Personally, I don't like using staples as they can accidentally puncture or skin the cable insulation. On larger NM Romex cable such as 6/3 type, I use either a 3/8" or a 1/2" one hole strap and then I slightly squeeze the clamp together to secure the able in place. NM Romex cable must be supported a maximum of 4'-6" intervals and within 12" of a box or a conduit body.
