Can I run 12-2 NM-B wire from my 20 amp dedicated breaker under my house and then using a four by four box splice 12-2 UF wire to run underground to my water pump house?

Running the wire would be in a dry crawl space, and the 4 x 4 box that the splice will be will also be in the dry crawl space mounted to a floor beam.

  • When you say "under my house". Do you mean in a dry basement/crawlspace, or under a slab/damp crawlspace?

    When you say 'under my house', do you mean like running through a crawlspace? And would the junction box be under the house too, mounted to the wall outside, or buried?

You can splice the NM above ground in a box above ground then run the UF to your pump. The depth for UF cable to be buried as you exit the foundation is 24” per NEC table 300.5.

    You can splice the NM in a box above ground, in a dry location.
