New circuit

Good day.

I just discovered this forum and have a feeling its going to help ease the pain of the home ownership.

Thanks in advance to anyone who can help with my basic questions.

I live in Miami and just purchased a home and I am renovating one of the bathrooms. I would like to add a dedicated circuit for the GFI. My panel is outside (not flush mounted) and has what seems to be plastic pipe/conduit that feeds the attic. I know in the attic I can use Romex, what can I use to get from the breaker panel to a J-box in the attic?

Thanks again
Nelson

Thanks Ray. That is exactly whats there now with the other wires. Can I pull Romex through that?

You can't really pull wire through an LB, but you can pull at the LB and leave yourself a long enough length of wire to reach the junction box and then pull that wire from the junction box in the attic. Does that make sense? If you want to pull through a 90 degree fitting you would use a 90 degree elbow instead of the LB condulet fitting. It's best practice to pull individual THHN/THWN conductors rather than pull a cable like romex. If you check the existing conduits, there may be some with available space to add more circuits; you do not have to have a separate conduit for each circuit.

Ray, are you stating that type NM cable is okay OUTSIDE as long as it is inside PVC conduit? That's the way I am reading your posts. I'm pretty sure that type NM is NEVER acceptable outside whether in conduit or not.

After doing some research I think my best bet will be to pull THWN through the short conduit that feeds the attic. My new question is how much "play" do I have once the THWN leaves the conduit in the attic? Meaning how far can I run to get it to the junction box before it has to be protected? Will a few feet be ok?

The individual conductors need to be in conduit for the entire run. That means conduit from the LB through the attic to the junction box.

Just to clarify, NM cannot be used outside even if sleeved in conduit.

No. I was apparently having a brain f*rt or senior moment. My posts have been deleted.
