Add new circuit in Electrical Panel
Here is probably a stupid question for those of you who have done this before, but I am installing a couple of 20Amp dedicated NEMA 5-20 outlets about 2 feet directly below my electrical panel in the garage. I will be using ROMEX 12-2 wire.
My question is, do I have to secure the ROMEX anywhere in between the panel and the outlet box? I know I have to use a cable clamp where the wires run out of the panel, but is that all that is required? Can I just have the wire go directly into the box and then onto screws of my outlet without further tie-down?
Another stupid question I have is about the cable clamp at the panel. Everything I've read says to have the clamp screw be OUTSIDE the panel. I can't do that because the panel is mounted inside wall. Is it ok to screw the clamp into the hole from the inside of the panel and also have the clamp screw to clamp the cable on the inside of the panel?
Sorry if this sounds stupid... but I'm a newbie to this and I figured a two foot run from the panel is a DIY job even for me.
