What is 14/1 thhn wire?

Either option is fine. No reason not to use Nm cable instead of conduit unless you have kids hanging out down there. hahaha

This is what I was planning to get except pay by the foot. 14/1 is just how I've seen it online on different sites.

 

That is the neutral wire. You need at least a black and white wire plus a green ground if the pipe is PVC. You may think bout running NM cable thru the pipe and not mess with the solid wire.

What size pipe are you running?

 

I planned on getting white, green and black. I posted only one link to show which wire I planned on getting. Thanks for pointing it out though, you never know. 3/4in PVC was the plan, that way if i can use the same conduit and j box if i decide to add an outlet to my garage for a fridge.

I've read you cannot run romex in conduit, especially going outside.

 

For that exterior pipe it would need to be UF, not Romex.

 

I advise having the GFCI protection at or near the panel. A lot easier to access for resetting, especially if you have to go outside to access the crawl space in a storm.
Also, get a power failure alarm. You don't want to wait until you flood before realizing it has tripped.

 

I like the idea of a power failure alarm. Any suggestions? The crawl space access is inside of my house and easily accessible, although outside might be preferred anyway. I'll look in to it!

 

They make plug-in alarms for a receptacle. Does not have to be at the receptacle the pump is on, just the same circuit at or after the GFCI.

 

Well it is all done. I got a 15amp breaker, ran 14 thhn wire to junction box and connected those to 14/2 romex with Wago connectors. Then ran 14/2 romex to an afci/gfci 15amp receptacle.

Any thoughts are appreciated. The white arrows are the things I added.

Overall looks good to me. The conductors on the Romex in the last picture looks shorter than code requires (I'd have to look up what the rule is), I think the slack you're supposed to have is measured starting from where outer jacket is stripped off.

First strap for Romex is not in the picture, that needs to be within 12". (You probably have one, jfyi)

 

If I'm doing this, I run 12 gauge on a 20 amp breaker
in case the next pump that gets installs requires it.

 

I appreciate the input! I did not think of that, most sump pumps I looked at only needed 15amp so it never crossed my mind to go bigger.

 

Additional conductor could be spliced on to meet the 6 inch if needed. I would leave it alone.

 

Oh really? The point of the rule is to have enough slack to make connections. That includes making the connection of putting on additional wire.

 

I agree with Jim. What happens on an old install where the wire is 3 inches from the back of the box? You splice on a longer piece so that you are working with enough wire to install the devices properly.

 

I understand and agree to splice on a piece when at a device. In this instance the splicing is to another wire in a junction box, no device. Therefore connecting a piece of wire to connect to another wire is superfluous.
